Chart of the Week: Why Congress Needs to Act on the Zika VirusAPRIL 6, 2016 AT 3:02 PM ET BY TANYA SOMANADERTWITTER FACEBOOK EMAIL Summary: Here's a map that estimates where the mosquitos that carry the Zika virus could potentially reach in the U.S.For months now, Americans who have been traveling or reading news reports have heard about the risk posed by the Zika virus, particularly those posed to pregnant women. In early January, President Obama convened his top advisors to formulate a proactive response to this epidemic -- including working closely with state and local elected officials, non-profits, health experts, and disease experts -- to contain and prevent the spread of the virus. In February, he asked Congress to support these efforts by providing $1.9 billion in emergency funding to combat Zika by supporting mosquito control, disease detection and testing, vaccine development, and support for maternal women's health. And since the President made that request, we've learned more concerning facts about this disease: Sexual transmission of the virus is more common than initially believedThe impact on fetal brain development is likely starker and more serious than first understoodIn the U.S., the geographical range of the particular mosquito that transmits Zika far exceeds our initial estimationThe Center for Disease Control has laid out an estimated range of the mosquitos that carry this disease in the United States this year. And while this map is not meant to represent risk for spread of the Zika virus, it shows where people may come into contact with the kinds of mosquitos that could be carrying this disease. We find ourselves in a rare moment where we have advance warning on a disease, and the likely birth defects that are associated with it, will be arriving in the U.S. Governors, state and local leaders are already working with us to get ahead of this threat. However, Congress continues to do nothing about the emergency funding. Because we cannot continue to fund a robust response to this disease without adequate resources, particularly for our partners in state and local government who will bear much of this burden, we are re-programming nearly $600 million of existing funds to address Ebola to help support our Zika response. This is not nearly enough to protect us from the significant threat posed by Zika. It’s a temporary fix, and not a long-term solution. As our Director of Management and Budget Shaun Donovan said this morning: As it gets warmer, the reach of these mosquitos will increase, and the need for a robust response will be more and more urgent. We have the opportunity to do get ahead of this epidemic, but Congress needs to do its part.

Taking Every Step Necessary, As Quickly As Possible, to Protect the American People from ZikaAPRIL 6, 2016 AT 11:00 AM ET BY SHAUN DONOVANTWITTER FACEBOOK EMAIL Summary: Nearly two months have passed since we submitted a request for emergency supplemental funding to combat the Zika virus. Congress has yet to act.The Administration is committed to taking every step necessary, as quickly as possible, to protect the American people from the Zika virus. That’s why we submitted to Congress a request for emergency supplemental funding in February to fortify our efforts to combat and stay ahead of the disease. But Congress has yet to act. Nearly two months have passed and the situation continues to grow more critical. Since we submitted the supplemental request to Congress, we have learned that sexual transmission of the virus is more common than believed; that the potential impact on fetal brain development is starker and more serious than first understood; and that within the United States the geographical range of the Aedis aegypti mosquito far exceeds our initial estimation. The Zika virus is spreading in Puerto Rico, the U.S. Virgin Islands, American Samoa, and abroad -- and there will likely be local mosquito-borne transmission in the continental United States in the upcoming spring and summer months. The World Health Organization (WHO) has stated there is a strong scientific consensus that the Zika virus is a cause of microcephaly and other poor pregnancy outcomes, Guillain-Barré Syndrome, and other neurological disorders. There is a confirmed case of a baby born with Zika-related microcephaly in Hawaii and there are additional microcephaly cases under investigation. As of last week, 33 countries and territories in the Americas reported active Zika transmission. We continue to call on Congress to take immediate action to provide the full requested amount for the emergency supplemental, but in the absence of Congressional action, we must scale up Zika preparedness and response activities now. Faced with this urgent need, we have identified $589 million – including $510 million of existing Ebola resources within the Department of Health and Human Services and Department of State/USAID – that can quickly be redirected and spent on immediate, time-critical activities such as mosquito control, lab capacity, development of diagnostics and vaccines, supporting affected expectant mothers and babies, tracking and mapping the spread and effects of Zika infections in humans, and other prevention and response efforts in the continental United States, Puerto Rico, other U.S. Territories, and abroad, especially within the Americas. We have always said that we were open to using a portion of the existing Ebola balances for Zika, but that this alone would not provide a sufficient enough response to the significant threat posed by Zika. This remains true. As such, the redirected funds are not enough to support a comprehensive Zika response and can only temporarily address what is needed until Congress acts on the Administration's emergency supplemental request. Emergency supplemental funding continues to be urgently needed to support the full range of activities needed to prevent, detect, and respond to further transmission of the Zika virus, including: Fortifying domestic and international public health systems; Accelerating vaccine research and development to provide a long-term strategy to limit the Zika virus;Enabling the development of better diagnostic tests, including tests that can be implemented in resource poor settings, and expanded laboratory capacity in both public health laboratories and in the private sector in the United States and abroad, particularly to meet the demand for Zika testing that we anticipate will dramatically increase; Conducting mosquito surveillance and deploying mosquito control tools, such as outdoor and indoor residual spraying, source reduction and larviciding, and widespread space spraying. In particular, as the rainy season gets underway in Central America and the Caribbean, these mosquito control efforts will be important internationally as well as domestically;Educating health care providers, pregnant women, and their partners;Supporting ongoing research efforts to improve our understanding of the Zika virus and its adverse health outcomes;Developing pathogen-reduction technology to help ensure the safety of the blood supply;Improving health services and support for low-income pregnant women; andEnhancing the ability of Zika-affected countries to better combat mosquitoes, control transmission, and support affected populations.Without the full amount of requested emergency supplemental funding, many activities that need to start now would have to be delayed, or curtailed or stopped, within months. For example, without supplemental funding, testing and manufacturing of vaccine candidates beyond the earliest stages of clinical trials would not be possible. In addition, lack of supplemental funding would prevent us from developing platform technologies for vaccine candidates for this Zika response and from accelerating the response to emerging infectious diseases in the future. Absent supplemental funding, we will need to delay contracting with manufacturers for the development of faster and more accurate diagnostic tests, which are needed to ensure that those who think they have been exposed to Zika can get tested. In particular, there is a critical need for point-of-care diagnostics that are faster and do not require laboratory capacity. Similarly, starting mosquito surveillance and control activities now, prior to the summer months which are peak season for mosquitoes, and prior to the start of the rainy season in Central America and the Caribbean, is prudent. Lack of funds could result in having to halt these efforts within months, which would increase the risk of more Americans contracting the Zika virus. Without supplemental funding, CDC would not be able to fully fund planned state grants for public health emergency preparedness, which would impede the ability for states to fully implement risk-based Zika preparedness and response plans. The full supplemental request is also needed to replenish the amounts that we are now spending from our Ebola accounts to fund Zika-related activities. The threat of Ebola remains front and center, as evidenced by the recent cases in Guinea and Liberia, and there is still critical work that is ongoing to make sure that we follow through on our Ebola response. There are currently 12 cases across Guinea and Liberia with nearly 1000 contacts under observation. Given the high-risk exposure of many of these contacts, we expect the case numbers to go up in the coming days. Replenishing the Ebola accounts will ensure we have sufficient contingency funds to address unanticipated needs related to both Zika and Ebola. As we have seen with both Ebola and Zika, there are still many unknowns about the science and scale of the outbreak and how it will impact mothers, babies, and health systems domestically and abroad. We urge Congress to act quickly on the emergency request for Zika to ensure we have funds to stay ahead of this disease, as well as Ebola, and do everything we can to protect the American people.

Washoe County reports first confirmed Zika case Symptoms consistent with Zika virus developed after returning from travel to El Salvador. Media ReleaseFor Immediate Releasewww.washoecounty.us/health Contact: Phil [email protected] or 775.772.1659 RENO, NV - A female adult with recent travel history to a Zika-affected country is the first confirmed Zika case in Washoe County according to health officials. The woman developed symptoms consistent with Zika virus after returning from travel to El Salvador. Those symptoms included joint pain, body ache, fever, conjunctivitis, chills, abdominal pain, headache and rash. Her symptoms resolved within a week. The woman is one of twelve individuals in Washoe County who have been tested in recent weeks. No other positive results have been received to date. "We will continue to monitor the lab tests we have submitted to the Centers for Disease Control and Prevention," said Washoe County District Health Officer Kevin Dick. "We know that the general public is concerned about the rise in the number of Zika cases, so this serves as a reminder that people going to Zika-affected countries, particularly those that are pregnant or intending to become pregnant, should take precautions to avoid being bitten by mosquitoes while traveling." Zika virus can be spread from a pregnant woman to her fetus and has been linked to a serious birth defect of the brain called microcephaly in babies of mothers who had Zika virus while pregnant. Zika virus is spread to people primarily through the bite of an infected Aedes species mosquito (Ae. aegyptiand Ae. albopictus). To date, Zika has not been spread by mosquitoes in the continental United States. However, lab tests have confirmed Zika virus in travelers returning to the United States from areas with Zika. Zika virus can also be spread during sex by a man infected with Zika to his partners. Some non-travelers in the United States have become infected with Zika through sex with a traveler. According to local health officials, the mosquitoes known to carry Zika virus are not indigenous to our area. While the mosquito may find its way to northern Nevada, it is not known whether the insect can survive in our climate. The best way to prevent diseases spread by mosquitoes is to protect yourself and your family from mosquito bites. Wear long-sleeved shirts and long pants.Stay in places with air conditioning and window and door screens to keep mosquitoes outside.Treat your clothing and gear with DEET or permethrin or buy pre-treated items.Use Environmental Protection Agency (EPA)-registered insect repellents. https://www.epa.gov/insect-repellents Sleep under a mosquito bed net if air conditioned or screened rooms are not available or if sleeping outdoors.To learn more, please visit CDC's Zika virus page at http://www.cdc.gov/zika/index.html.

April 11, 2016 DEPARTMENT OF HEALTH DAILY ZIKA UPDATE: ONE NEW TRAVEL-RELATED CASE IN LEE COUNTY Contact:Communications [email protected](850) 245-4111 Tallahassee, Fla.—In an effort to keep Florida residents and visitors safe and aware about the status of the Zika virus, the Florida Department of Health will issue a Zika virus update each week day at 2 p.m. Updates will include a CDC-confirmed Zika case count by county and information to better keep Floridians prepared. There is one new travel-related case in Lee County today.Of the cases confirmed in Florida, six cases are still exhibiting symptoms. According to the CDC, symptoms associated with the Zika virus last between seven to 10 days. Based on CDC guidance, several pregnant women who have traveled to countries with local-transmission of Zika have received antibody testing, and of those, five have tested positive for the Zika virus. The CDC recommends that a pregnant woman with a history of Zika virus and her provider should consider additional ultrasounds. It is recommended that women who are pregnant or thinking of becoming pregnant postpone travel to Zika affected areas. County Number of Cases (all travel related) Alachua 4 Brevard 2 Broward 13 Clay 1 Collier 1 Hillsborough 3 Lee 4 Miami-Dade 33 Orange 5 Osceola 4 Palm Beach 4 Polk 3 Santa Rosa 1 Seminole 1 St. Johns 1 Cases involving pregnant women* 5 Total 85 *Counties of pregnant women will not be shared. On Feb. 12, Governor Scott directed the State Surgeon General to activate a Zika Virus Information Hotline for current Florida residents and visitors, as well as anyone planning on traveling to Florida in the near future. The hotline, managed by the Department of Health, has assisted 1,333 callers since it launched. The number for the Zika Virus Information Hotline is 1-855-622-6735. All cases are travel-associated. There have been no locally-acquired cases of Zika in Florida. For more information on the Zika virus, click here. The department urges Floridians to drain standing water weekly, no matter how seemingly small. A couple drops of water in a bottle cap can be a breeding location for mosquitoes. Residents and visitors also need to use repellents when enjoying the Florida outdoors. More Information on DOH action on Zika: On Feb. 3, Governor Scott directed the State Surgeon General to issue a Declaration of Public Health Emergency for the counties of residents with travel-associated cases of Zika.The Declaration currently includes the 15 affected counties – Alachua, Brevard, Broward, Clay, Collier, Hillsborough, Lee, Miami-Dade, Orange, Osceola, Palm Beach, Polk, Santa Rosa, Seminole and St. Johns – and will be updated as needed. DOH encourages Florida residents and visitors to protect themselves from all mosquito-borne illnesses by draining standing water; covering their skin with repellent and clothing; and covering windows with screens.DOH has a robust mosquito-borne illness surveillance system and is working with the CDC, the Florida Department of Agriculture and Consumer Services and local county mosquito control boards to ensure that the proper precautions are being taken to protect Florida residents and visitors.On April 6, Governor Rick Scott and Interim State Surgeon General Dr. Celeste Philip hosted a conference call with Florida Mosquito Control Districts to discuss ongoing preparations to fight the possible spread of the Zika virus in Florida. There were 74 attendees on the call.Florida currently has the capacity to test 6,821 people for active Zika virus and 1,603 for Zika antibodies.Federal Guidance on Zika: According to the CDC, Zika illness is generally mild with a rash, fever and joint pain. CDC researchers are examining a possible link between the virus and harm to unborn babies exposed during pregnancy.The FDA released guidance regarding donor screening, deferral and product management to reduce the risk of transfusion-transmission of Zika virus. Additional information is available on the FDA website here.The CDC has put out guidance related to the sexual transmission of the Zika virus. This includes the CDC recommendation that if you have traveled to a country with local transmission of Zika you should abstain from unprotected sex.For more information on Zika virus, click here.

Zika impairs growth in human neurospheres & brain organoids - Science
niman replied to niman's topic in Zika Virus
Aedes aegypti mosquitoes Paulo Whitaker / Reuters SHARE Two studies published this week show that the Zika virus seems to prefer brain cells — and that it can cause many different types of damage to those cells. One of the studies shows that Zika — but not its close cousin, the dengue virus — destroys developing nerve cells. Another describes the cases of two Zika patients who developed nerve damage similar to that caused by multiple sclerosis. Confocal microscopy of human neural stem cell culture infected with Zika virus (red). Cell nuclei are shown in blue. Credit: Erick Loiola, PhD and Rodrigo Madeiro, PhD - IDOR / ScienceBoth add to the growing body of evidence that Zika virus, once virtually ignored as a rather harmless infection, is causing severe and sometimes deadly birth defects and other types of damage to victims of all ages. And because it's spreading so fast among so many people, it's adding up to thousands of victims. Patricia Garcez of the Federal University of Rio de Janeiro in Brazil and colleagues used human induced pluripotent stem (iPS) cells — lab-created stem cells — which they coaxed into become immature brain cells. Zika virus infected and killed them, they report in the journal Science. When they directed these iPS cells to become little batches of brain cells, the virus slowed their growth and development by 40 percent. But when Garcez's team tried the same thing with dengue virus, they did not see the same effects. The virus, which is very closely related to Zika, infected the nerve and brain cells but did not kill them. "THOUGH OUR STUDY IS SMALL, IT MAY PROVIDE EVIDENCE THAT IN THIS CASE THE VIRUS HAS DIFFERENT EFFECTS ON THE BRAIN THAN THOSE IDENTIFIED IN CURRENT STUDIES."This helps explain why Zika's effects were so unexpected. Viruses such as rubella and those in the herpes family are well known to cause birth defects and sometimes severe neurological effects in adults and children. But not so-called flaviviruses such as Zika and its cousin dengue. Zika was once believed to cause little more than a rash and some achiness - and even then only in a small percentage of people infected. Now it's known it can have serious effects on developing fetuses and adults as well. A second study shows more startling neurological effects. Dr. Maria Lucia Brito Ferreira of Restoration Hospital in Recife, Brazil and colleagues described the cases of two Zika patients who developed a condition called acute disseminated encephalomyelitis. It's an inflammation of the brain and spinal cord that damages the protective fatty myelin layer that covers nerve cells. That's similar to what multiple sclerosis does, but it's usually temporary - although the recovery can take months. Four more patients developed Guillain-Barre syndrome, a paralyzing condition hat's also caused by nerve damage, Ferreira's team said in remarks released ahead of an annual meeting of the American Academy of Neurology. "Though our study is small, it may provide evidence that in this case the virus has different effects on the brain than those identified in current studies," said Ferreira. When they left the hospital, five of the six people still had problems with movement and coordination and one had memory problems. "This doesn't mean that all people infected with Zika will experience these brain problems. Of those who have nervous system problems, most do not have brain symptoms," said Ferreira. "However, our study may shed light on possible lingering effects the virus may be associated with in the brain." Zika's spreading in both Latin America and the South Pacific. The mosquito-borne virus is blamed for thousands of birth defects, notably one called microcephaly, marked by an underdeveloped brain and head. The World Health Organization and the Centers for Disease Control and Prevention both warn travelers going to Zika-affected regions to do what they can to avoid mosquito bites. They're telling pregnant women to stay away completely if they can. Both also warn travelers who may bring Zika back home to avoid infecting loved ones sexually and to watch out not to get bitten by mosquitoes at home. The CDC predicts small, localized outbreaks in the U.S. as warmer weather fuels the breeding of the mosquitoes that spread Zika. http://www.nbcnews.com/health/health-news/there-s-more-evidence-zika-goes-straight-brain-n554041 -

Zika impairs growth in human neurospheres & brain organoids - Science
niman replied to niman's topic in Zika Virus
Primary microcephaly is a severe brain malformation characterized by the reduction of the head circumference. Patients display a heterogeneous range of brain impairments, compromising motor, visual, hearing and cognitive functions (1). Microcephaly is associated with decreased neuronal production as a consequence of proliferative defects and death of cortical progenitor cells (2). During pregnancy, the primary etiology of microcephaly varies from genetic mutations to external insults. The so-called TORCHS factors (Toxoplasmosis, Rubella, Cytomegalovirus, Herpes virus, Syphilis) are the main congenital infections that compromise brain development in utero (3). The increase in the rate of microcephaly in Brazil has been associated with the recent outbreak of Zika virus (ZIKV) (4, 5), a flavivirus that is transmitted by mosquitoes (6) and sexually (7–9). So far, ZIKV has been described in the placenta and amniotic fluid of microcephalic fetuses (10–13), and in the blood of microcephalic newborns (11, 14). ZIKV had also been detected within the brain of a microcephalic fetus (13, 14), and recently, there is direct evidence that ZIKV is able to infect and cause death of neural stem cells (15). Here, we used human induced pluripotent stem (iPS) cells cultured as neural stem cells (NSC), neurospheres and brain organoids to explore the consequences of ZIKV infection during neurogenesis and growth with 3D culture models. Human iPS-derived NSCs were exposed to ZIKV (MOI 0.25 to 0.0025). After 24 hours, ZIKV was detected in NSCs (Fig. 1, A to D), when viral envelope protein was shown in 10.10% (MOI 0.025) and 21.7% (MOI 0.25) of cells exposed to ZIKV (Fig. 1E). Viral RNA was also detected in the supernatant of infected NSCs (MOI 0.0025) by qRT-PCR (Fig. 1F), supporting productive infection.

To investigate the effects of ZIKV during neural differentiation, mock- and ZIKV-infected NSCs were cultured as neurospheres. After 3 days in vitro, mock NSCs generated round neurospheres. However, ZIKV-infected NSCs generated neurospheres with morphological abnormalities and cell detachment (Fig. 2B). After 6 days in vitro (DIV), hundreds of neurospheres grew under mock conditions (Fig. 2, C and E). Strikingly, in ZIKV-infected NSCs (MOI 2.5 to 0.025) only a few neurospheres survived (Fig. 2, D and E).

Mock neurospheres presented expected ultrastructural morphology of nucleus and mitochondria (Fig. 3A). ZIKV-infected neurospheres revealed the presence of viral particles, similarly to those observed in murine glial and neuronal cells (16). ZIKV was bound to the membranes and observed in mitochondria and vesicles of cells within infected neurospheres (Fig. 3, B and F, arrows). Apoptotic nuclei, a hallmark of cell death, were observed in all ZIKV-infected neurospheres analyzed (Fig. 3B). Of note, ZIKV-infected cells in neurospheres presented smooth membrane structures (SMS) (Fig. 3, B and F), similarly to those previously described in other cell types infected with dengue virus (17). These results suggest that ZIKV induces cell death in human neural stem cells and thus impairs the formation of neurospheres.

To further investigate the impact of ZIKV infection during neurogenesis, human iPS-derived brain organoids (18) were exposed with ZIKV, and followed for 11 days in vitro (Fig. 4). The growth rate of 12 individual organoids (6 per condition) was measured during this period (Fig. 4, A and D). As a result of ZIKV infection, the average growth area of ZIKV-exposed organoids was reduced by 40% when compared to brain organoids under mock conditions (0.624 mm2 ± 0.064 ZIKV-exposed organoids versus 1.051 mm2 ± 0.1084 mock-infected organoids normalized, Fig. 4E).

In addition to MOCK infection, we used dengue virus 2 (DENV2), a flavivirus with genetic similarities to ZIKV (11, 19), as an additional control group. One day after viral exposure, DENV2 infected human NSCs with a similar rate as ZIKV (fig. S1, A and B). However, after 3 days in vitro, there was no increase in caspase 3/7 mediated cell death induced by DENV2 with the same 0.025 MOI adopted for ZIKV infection (fig. S1, C and D). On the other hand, ZIKV induced caspase 3/7 mediated cell death in NSCs, similarly to the results described by Tang and colleagues (15). After 6 days in vitro, there is a significant difference in cell viability between ZIKV-exposed NSCs compared to DENV2-exposed NSCs (fig. S1, E and F). In addition, neurospheres exposed to DENV2 display a round morphology such as uninfected neurospheres after 6 days in vitro (fig. S1G). Finally, there was no reduction of growth in brain organoids exposed to DENV2 for 11 days compared to MOCK (1.023 mm2 ± 0.1308 DENV2-infected organoids versus 1.011 mm2 ± 0.2471 mock-infected organoids normalized, fig. S1, H and I). These results suggest that the deleterious consequences of ZIKV infection in human NSCs, neurospheres and brain organoids are not a general feature of the flavivirus family. Neurospheres and brain organoids are complementary models to study embryonic brain development in vitro (20, 21). While neurospheres present the very early characteristics of neurogenesis, brain organoids recapitulate the orchestrated cellular and molecular early events comparable to the first trimester fetal neocortex, including gene expression and cortical layering (18, 22). Our results demonstrate that ZIKV induces cell death in human iPS-derived neural stem cells, disrupts the formation of neurospheres and reduces the growth of organoids (fig. S2), indicating that ZIKV infection in models that mimics the first trimester of brain development may result in severe damage. Other studies are necessary to further characterize the consequences of ZIKV infection during different stages of fetal development. Cell death impairing brain enlargement, calcification and microcephaly is well described in congenital infections with TORCHS (3, 23, 24). Our results, together with recent reports showing brain calcification in microcephalic fetuses and newborns infected with ZIKV (10, 14) reinforce the growing body of evidence connecting congenital ZIKV outbreak to the increased number of reports of brain malformations in Brazil.

Zika impairs growth in human neurospheres & brain organoids - Science
niman replied to niman's topic in Zika Virus
AbstractSince the emergence of Zika virus (ZIKV), reports of microcephaly have increased significantly in Brazil; however, causality between the viral epidemic and malformations in fetal brains needs further confirmation. Here, we examine the effects of ZIKV infection in human neural stem cells growing as neurospheres and brain organoids. Using immunocytochemistry and electron microscopy, we show that ZIKV targets human brain cells, reducing their viability and growth as neurospheres and brain organoids. These results suggest that ZIKV abrogates neurogenesis during human brain development. -

Apr 11, 2016Zika Virus Tied to MS-like Brain DisorderScientists report that the Zika virus may be associated with an autoimmune disorder that attacks the brain's myelin similar to multiple sclerosis. The investigators will discuss the results of their research at the upcoming American Academy of Neurology's 68th Annual Meeting in Vancouver, Canada. "Though our study is small, it may provide evidence that in this case the virus has different effects on the brain than those identified in current studies," said study author Maria Lucia Brito Ferreira, MD, with Restoration Hospital in Recife, Brazil. "Much more research will need to be done to explore whether there is a causal link between Zika and these brain problems." For the study, researchers followed people who came to the hospital in Recife from December 2014 to June 2015 with symptoms compatible with arboviruses, the family of viruses that includes Zika, dengue and chikungunya. Six people then developed neurologic symptoms that were consistent with autoimmune disorders and underwent exams and blood tests. The authors saw 151 cases with neurological manifestations during a period of December 2014 to December 2015. All of the people came to the hospital with fever followed by a rash. Some also had severe itching, muscle and joint pain and red eyes. The neurologic symptoms started right away for some people and up to 15 days later for others. Of the six people who had neurologic problems, two of the people developed acute disseminated encephalomyelitis (ADEM), an attack of swelling of the brain and spinal cord that attacks the myelin. In both cases, brain scans showed signs of damage to the brain's white matter. Unlike MS, acute disseminated encephalomyelitis usually consists of a single attack that most people recover from within six months. In some cases, the disease can reoccur. Four of the people developed Guillain-Barré syndrome (GBS), a syndrome that involves myelin of the peripheral nervous system and has a previously reported association with the Zika virus. When they were discharged from the hospital, five of the six people still had problems with motor functioning. One person had vision problems and one had problems with memory and thinking skills. Tests showed that the participants all had Zika virus. Tests for dengue and chikungunya were negative. "This doesn't mean that all people infected with Zika will experience these brain problems. Of those who have nervous system problems, most do not have brain symptoms," said Dr. Ferreira. "However, our study may shed light on possible lingering effects the virus may be associated with in the brain." "At present, it does not seem that ADEM cases are occurring at a similarly high incidence as the GBS cases, but these findings from Brazil suggest that clinicians should be vigilant for the possible occurrence of ADEM and other immune-mediated illnesses of the central nervous system," noted James Sejvar, MD, with the Centers for Disease Control and Prevention in Atlanta and a member of the American Academy of Neurology. "Of course, the remaining question is 'why'-why does Zika virus appear to have this strong association with GBS and potentially other immune/inflammatory diseases of the nervous system? Hopefully, ongoing investigations of Zika virus and immune-mediated neurologic disease will shed additional light on this important question." http://www.genengnews.com/gen-news-highlights/zika-virus-tied-to-ms-like-brain-disorder/81252591/

Scientists already suspect the mosquito and sex-spread virus causes fetal brain disorder and temporary paralysis. Analysis Zika virus: its effects, how it is spread, and the possible threat to womenThe disease is believed to have infected 1.5 million people since its outbreak in Brazil and dramatic spread around the world Read moreThe study followed patients with symptoms of arboviruses, the family of infectious agents that includes Zika and dengue, who came to a hospital in Recife, Brazil, between December 2014 and June 2015. Six people developed neurological symptoms and two suffered attacks that swelled the brain and damaged its myelin, the fatty material that protects nerves there and at the spinal cord. The research was presented on Sunday at the annual conference for the American Academy of Neurology in Vancouver. Its abstract concluded that “there is strong evidence that this epidemic has different neurological manifestations” than those already documented. All the people arrived in the hospital with a fever, then a rash, and some suffered red eyes, itching and aching muscles and joints – the known symptoms of the Zika virus. The neurological symptoms sometimes began immediately, or as long as 15 days after patients first sought treatment. All six people tested positive for the Zika virus, and negative for dengue fever and chikungunya. After they left hospital, five reported problems with motor functioning; one reported trouble with vision and memory. “Though our study is small, it may provide evidence that in this case the virus has different effects on the brain than those identified in current studies,” said the study’s author, Dr Maria Lucia Brito Ferreira of the Restoration hospital in Recife, Brazil. Brito Ferreira repeated a common refrain of Zika research: the research is early and still inconclusive, and meant to add to the growing investigation to discover what the virus actually does. In all, her team documented 151 cases with neurological symptoms. “This doesn’t mean that all people infected with Zika will experience these brain problems,” Ferreira said. “Of those who have nervous system problems, most do not have brain symptoms. Advertisement“However, our study may shed light on possible lingering effects the virus may be associated with in the brain.” The brain swelling, called acute disseminated encephalomyelitis (ADEM), resembles multiple sclerosis in some symptoms but is not a permanent condition. ADEM usually consists of a single or occasional attack, from which most people can recover over several months. Four of the people followed for Ferreira’s research developed Guillain-Barré syndrome (GBS), a serious brain condition that enervates muscles, and can leave people temporarily paralyzed and breathing through ventilators. Like ADEM, the condition attacks myelin, and many people also recover from GBS after several months. Earlier this year, scientists published strong evidence that Zika is linked to GBS through a study on 42 cases in French Polynesia. Dr James Sejvar, a neurologist with the US Centers for Disease Control and Prevention, said that cases of ADEM do not appear to afflict people with Zika as often as cases of GBS. “But these findings from Brazil suggest that clinicians should be vigilant,” he said, for signs of ADEM and other central nervous system diseases. “Of course, the remaining question is ‘why,’” Sejvar said. “Why does Zika virus appear to have this strong association with GBS and potentially other immune-inflammatory diseases of the nervous system?” Experts at the World Health Organization also “implicated” Zika in a disorder called microcephaly, which causes babies to suffer brain damage and abnormally small heads. In February, a few days after experts warned that the virus could be a greater threat than Ebola, the organization declared a global public health emergency. Scientists have yet to confirm what conditions the virus actually causes, although research has raced to study the once rare pathogen, which emerged from a remote forest in Uganda. That the evidence is still inconclusive has many scientists cautioning the public and leaders not to fuel hysteria around it. http://www.theguardian.com/world/2016/apr/10/zika-virus-brain-disorders-brazil-study

Zika may be associated with other neurological diseaseBy: Robério SáMonday | 11.04.2016 at 09:23 error_outlinecommunicate error Estadão In addition to the microcephaly and Guillain-Barré syndrome, Zika virus may be associated with another neurological disease: acute disseminated encephalomyelitis (ADEM, in its English acronym), autoimmune syndrome that causes inflammation in the central nervous system. A study in Recife, which will be released on Friday at the annual meeting of the American Academy of Neurology, in Vancouver, Canada, found evidence of association between the virus and the ADEM in at least two cases. Scientists have suspected a connection between zika and ADEM, as shown by the newspaper O Estado de S. Paulo in February. But only now will present the scientific results of the study led by Maria Lucia Ferreira Brito, head of the Restoration Hospital Neurology Service in Recife. "Although it is a small study, it can provide evidence that the virus causes brain effects different from those that had been identified in the ongoing studies. But a lot of research still needs to be done to explore whether there is a causal relationship between zika and these brain problems, "said Maria Lucia. In the study, scientists followed between December 2014 and June 2015, all cases brought to the Restoration Hospital with symptoms of infection by arboviruses - the family of viruses that includes zika, dengue and chikungunya. All patients arrived at the hospital with fever and rash. Some also had itches, pains in muscles and joints, and red eyes. Some had neurological symptoms soon after and the other had about 15 days later. The authors recorded 151 cases with some type of neurological manifestation, but six of them developed typical neurological symptoms of autoimmune diseases - those in which the patient's immune system attacks and destroys healthy tissue cells of your own body. The six patients underwent blood tests and tests. Four had Guillain-Barré syndrome, as well as microcephaly, has been linked to infection zika. The other two were diagnosed with ADEM. The tests revealed that the six had been infected zika, but none of chikungunya or dengue. In patients with ADEM, according to experts, the defense cells of the body in the brain and spinal cord attack the myelin sheath a fat covering that surrounds nerve fibers and has function similar to the cover of a wire conductor of electricity. Guillain-Barré syndrome is also autoimmune and involves damage to the myelin sheath. damage In both reported cases, the brain scans showed that patients with ADEM had signs of damage in brain white matter. According to scientists, they are similar to the symptoms of a multiple sclerosis ADEM but in general causes a single attack which most patients recover in about six months. When discharged from hospital, five of the six patients continued with motor problems. One had vision problems and another had problems with memory and thinking ability. "This does not mean that all people infected with zika have this type of brain problem. Of those who had nervous system problems, most do not have cerebral symptoms. However, our study may help clarify possible lasting effects with which the virus can be associated in the brain, "said Maria Lucia. "Right now, it does not seem that cases of ADEM are occurring with an incidence as large as the cases of Guillain-Barré, but these findings in Brazil suggest that physicians should be vigilant about the possible occurrence of ADEM and other diseases autoimmune related to the central nervous system, "said James Sejvar, the Center for Disease Control and Prevention (CDC, its acronym in English) in Atlanta, USA. "The question is: why zika virus seems to have this strong association with Guillain-Barré syndrome and potentially other autoimmune and inflammatory diseases of the nervous system," questioned Sejvar.
