- Contaminated air. In areas with high concentrations of infected birds, the virus may be present in dust and air particles, increasing the risk of inhaling the virus.
- Eating raw or undercooked poultry products. Although less common, there is a risk if contaminated poultry products that have not been cooked properly are consumed.
