Action Plan on Avian Influenza include strengthening the biosecurity of poultry farms, disinfection of affected areas, proper disposal of dead birds/carcasse
Avian Influenza (AI) viruses have been circulating worldwide for centuries with four known major outbreaks recorded in the last century. India notified the first outbreak of avian influenza in 2006. 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, as well as cooking and processing standards, are effective means of controlling the spread of the AI viruses.
In India, the disease spreads mainly by migratory birds coming into India during winter months i.e. from September – October to February – March. The secondary spread by human handling (through fomites) cannot be ruled out.
