The Latest on Bird Flu in Humans, Cats and Chickens
Briefly

As of January 23, 2024, the ongoing bird flu outbreak in the U.S. has seen 67 confirmed human cases, with the first death reported earlier this month. While the CDC indicates no human-to-human transmission, infections primarily stem from exposure to sick cattle and poultry, which can shed the H5N1 virus, especially in dairy milk. The outbreak has severely impacted poultry, with over 140 million birds infected or culled since February 2022, and recent clusters of infection reported among commercial farms in Georgia, Maryland, and Virginia.
The first U.S. death from bird flu was announced earlier this month in Louisiana, but most human cases in the country have remained quite mild.
The CDC maintains that there is no evidence of spread between humans; most people with avian influenza have been infected through exposure to sick dairy cows or poultry.
As of January 23, the U.S. Department of Agriculture reported that there were 98 infected flocks within the past 30 days, with more than 15 million birds affected.
Since the bird flu outbreak began in February 2022, more than 140 million birds have been infected or proactively culled.
