  • It is an infection caused in birds by the Type A viruses, mostly found in wild aquatic or wild birds.
  • The virus can infect birds including domestic poultry like chicken, ducks, turkeys and geese, and animals.

  • Transmission: The virus is transmitted when a domestic bird comes in contact with the waterfowl or another infected bird or through a virus-contaminated surface.
    • The virus can spread from the faeces, secretion from nose, mouth and eyes of an infected bird.

The disease record in India

  • The country was declared free from avian influenza in July 2015 after completion of disinfection and post operation surveillance.
  • The H5N8 strain of avian influenza outbreaks have been reported from 2010 in Asia and was first found in domestic ducks in China.

Does the flu affect humans?

  • The two strains that can infect humans in the past are H5N1 and H7N9.
  • The disease, however, when transmitted to humans (through the droppings, and secretions of an infected bird) can be dangerous in nature.
