CDC Confirms First Human Case of Bird Flu in Oregon

 On November 15, the U.S. Centers for Disease Control and Prevention (CDC) announced Oregon's first confirmed human case of highly pathogenic avian influenza (HPAI). The case is linked to a prior outbreak at a commercial poultry facility in the state, where approximately 150,000 birds were affected, according to the state health department.

So far this year, 52 individuals across eight states in the U.S. have tested positive for the virus. Most cases involve farm workers with direct exposure to infected animals, except for one case in Missouri.

Health officials have not disclosed detailed information about the individual in Oregon but emphasized that there is no evidence of human-to-human transmission, and the overall public health risk remains low.

In a related event last month, the H5N1 strain was detected in a pig on a small farm in Oregon, marking the first instance of the virus being found in swine within the U.S.

The CDC advises farm workers who come into contact with infected animals to undergo testing, even if they do not exhibit symptoms. Since the outbreak began in 2022, over 100 million poultry birds have been lost, making it the largest bird flu outbreak in U.S. history.
