  • Infection in humans is not yet reported in India though the disease is zoonotic.
  • There is no direct evidence that AI viruses can be transmitted to humans via the consumption of contaminated poultry products. 
  • Implementing management practices that incorporate bio security principles, personal hygiene, and cleaning and disinfection protocols are effective means of controlling the spread of the AI viruses.
