Update: Domestic H5 Outbreak in BirdsInvestigation into initial human exposures to H5-infected birds suggests risk of human infection is low Language:EnglishEspañolRecommend on FacebookTweetJuly 24, 2015 - - A report published in Emerging Infectious Diseases (EID) today sheds light on the human health risk posed by newly detected highly pathogenic avian influenza H5 viruses in birds in the United States. The investigation identified 164 people exposed to domestic H5 viruses in the United States from December 15, 2014, to March 31, 2015. While some of these exposures included contact with infected birds none have resulted in human infection. These findings support CDC’s cu…

New CDC Laboratory Study Suggests U.S. H5 Bird Flu Viruses Currently Pose Low Risk to PeopleLanguage:EnglishEspañolRecommend on FacebookTweetA new CDC study describes findings from a series of CDC laboratory experiments designed to improve understanding of the human health risk posed by two H5 bird flu viruses detected in birds in the United States: H5N2 and H5N8. Findings of this study indicate that the H5N2 and H5N8 bird flu viruses detected in the United States were less lethal in mammals and replicated (made copies of themselves during infection) at a lower level than the H5 bird flu viruses from Asia that have caused infections, serious illness and deaths in people. …
