Avian Influenza
Avian Influenza Playbook
Avian Influenza is a disease caused by infection with avian influenza A virus. Avian Influenza can sicken and kill wild and domesticated birds. Although bird flu viruses do not normally infect people, rare cases of illness in humans from bird flu virus infections have occurred

About Avian Flu
- Avian Influenza is caused by infection with avian influenza A viruses (such as H5N1, H7N9)
- The disease primarily affects wild and domesticated birds, often causing severe illness and death
- Although bird flu viruses do not typically infect humans, rare cases of illness in humans have occurred after direct or indirect exposure to infected birds, animals, or contaminated environments
- Human H5N1 cases historically have had a high mortality rate (50-60% worldwide)
- Most human cases are linked to direct contact with infected poultry, dairy cattle, or wild birds (animal-to-human)
- Contact with contaminated surfaces, raw or undercooked poultry, meat, or unpasteurized milk can result in (environmental exposure)
- Sustained person-to-person transmission has not been observed. However, isolated mutations in virus samples from humans show potential for adaptation (human-to-human)
- Incubation Period: 2 to 8 days, but can extend to 17 days
- Influenza-like illness
- First identified in the late 1990s outbreak in poultry and humans in Asia
- H5N1 has since become enzootic in wild birds, causing reated poultry outbreaks across Asia, Africa, Europe, and North America
- The United States last detected Avian Influenza in 2022. Where H5N1 was detected in wild birds, commercial poultry flocks, dairy herds, and some mammalian species across multiple states
- Avian influenza remains widespread in wild birds globally
- Avian Influenza A viruses have been found in raw milk and raw meat products in the United States, creating additional exposure risks
