Bird Flu May Spread Through the Air, Study Finds

THURSDAY, Feb. 20, 2025 (HealthDay News) -- The highly contagious H5N1 bird flu virus may be spreading through the air under certain conditions, according to a new study from the Czech Republic.

Government veterinarians made the discovery while investigating a mysterious outbreak at a highly secured chicken farm last February.

The farm had strict biosecurity measures -- filtered well water, one-way airflow fans and fencing to keep wild animals out. Yet, the virus still infected the flock, causing thousands of bird deaths.

The likely culprit? Wind.
