Current Bird Flu Situation

Updated January 15, 2025​

-- ​​​​The current risk to the public remains low.  ​​

-- No person-to-person spread of bird flu has been detected in California. 

-- People rarely get bird flu, but those who interact​ with infected dairy cows, poultry, or wildlife ​have a greater risk of infection.​​

-- Pasteurized milk and dairy products are safe to consume. Pasteurization inactivates the bird flu virus.​​

-- CDPH is working to protect public health related to bird flu. We monitor infection data, evolving science, and the people affected. Our knowledge will change as we learn more. We are committed to reducing the impact to those at highest risk.

#PuertoRico - High pathogenicity avian #influenza #H5N1 viruses (#poultry) (Inf. with) - Immediate notification

Highly pathogenic avian influenza (HPAI) H5N1 clade 2.3.4.4b was confirmed on one poultry premises in Culebra Municipality, Puerto Rico . This is the first confirmed case of HPAI in poultry from Puerto Rico. Full genotyping confirms the virus as a reassortant of the A3 genotype with North American wild bird lineage viruses ( AM PB2, PA, NP ). Comparisons of the virus to other recent detections from wild birds and North America reports are in progress. The USDA Animal and Plant Health Inspection Service (APHIS), in conjunction with State Animal Health and Wildlife Officials, are conducting comprehensive epidemiological investigations and enhanced surveillance in response to the HPAI H5N1 related events.
