MCPH is working with California Department of Public Health (CDPH) and the Center for Disease Control (CDC) on additional testing to confirm if this infection was bird flu or seasonal flu. The child has recovered and no other family members became sick, indicating no person-to-person transmission. People rarely get bird flu, but those who interact with infected dairy cows, poultry, or wildlife have a greater risk of infection. The current risk to the public remains low. Health Care Providers: On December 6th, CDPH released an alert(link is external) advising healthcare providers to consider avian flu in symptomatic persons who consumed raw milk products. Contact Marin County Public Health to coordinate testing for suspected avian influenza A (H5N1) in persons with signs and symptoms consistent with acute respiratory tract or gastrointestinal infection and/or conjunctivitis with history of consuming raw milk in the past 10 days. During business hours, call 415-473-4163 to coordinate testing. Dairies & Cattle Farms: Call 1-866-922-2473 to report an unusual number of sick livestock or if you suspect Bird Flu in your livestock.

H5N1 bird flu is a specific strain or type of influenza virus. H5N1 bird flu is also called highly pathogenic avian influenza (HPAI). H5N1 bird flu can infect wild birds, poultry, and mammals such as cows. Human infections with H5N1 bird flu are rare, but spread of the virus may lead to changes that make it more likely to infect humans. Public Health Recommendations CDC has indicated that the current risk to the general public from H5N1 bird flu is low. People should: Wash your hands regularly, especially before eating and after interacting with animals. Avoid unprotected exposures to sick or dead animals including wild birds, poultry, and other domesticated birds. Handling sick or dead animals safely requires personal protective equipment and training. Do not drink or eat unpasteurized (raw) milk or raw cheese. Raw milk and cheese have not gone through a process called pasteurization that kills disease-causing germs. The milk of cows infected with H5N1 carries live virus. For more information about how raw milk can make you sick, visit the CDC’s Raw Milk web page(link is external). Recommendations for Agricultural Workers People who have job-related or recreational exposure to infected animals, including wild birds, poultry, and dairy cows, are at greater risk of being exposed to H5N1 bird flu. People at higher risk should: Follow all CDC recommendations(link is external) for worker protection to reduce the risk of infection Call your health care provider if you feel sick. Symptoms of H5N1 bird flu can include red or watery eyes, cough, sore throat, and fever. The California Department of Public Health has also created an educational flyer for agricultural workers about H5N1 bird flu.

The child went to a local emergency department in November with fever and vomiting after drinking raw milk and tested positive for influenza A, the county said. More testing is underway to determine whether the child had H5N1 bird flu. The child recovered and no family members became ill.

While pasteurized milk goes through a heating process that kills harmful pathogens, raw milk is not pasteurized and can carry listeria, campylobacter, salmonella, E. coli and bird flu virus. Distribution from Fresno-based Raw Farm was halted in November after bird flu was identified in milk products from store shelves, dairy storage and bottling sites. Raw Farm has said it has paused production while its herd is under quarantine. Bird flu has continued to spread in wild birds, poultry and dairy cattle around the United States since spring. There’s no evidence of person-to-person spread but scientists worry the virus can mutate to spread more easily among people. The US Department of Agriculture announced last week a plan to expand testing of milk bound for pasteurization in order to better track the spread of bird flu.

Fifty-eight bird flu cases have been confirmed in humans in the United States so far this year, including 32 in California. Most are linked to farm workers who have been in contact with sick animals. California also reported last month the first US case identified in a child; the US Centers for Disease Control and Prevention said Tuesday that the virus from that case resembled those previously detected in humans, cattle and poultry in California but it’s not clear how the child was exposed. In an alert to health-care providers last week, the California Department of Health said doctors should consider bird flu in people with acute respiratory symptoms or conjunctivitis who’ve had recent exposure to animals with bird flu or who have recently consumed raw dairy products. Bird flu symptoms in humans include typical flu-like symptoms such as eye redness, sore throat, runny nose, cough, diarrhea, vomiting, body aches, fatigue, trouble swallowing or fever. https://www.cnn.com/2024/12/11/health/california-bird-flu-child-raw-milk-marin/index.html
