Figure 2

Transmission dynamics of avian influenza virus in the different poultry production systems of Bangladesh. (a) Shows four different poultry farm settings, which also shows poor biosecurity management in the farms. The virus can move from commercial farms to backyard poultry farms or vice versa by stray dogs, cats, resident birds, and human workers (b). The virus can spread through the live poultry and egg transportation system (c), resident wild animals, such as foxes, mink, ferrets, rodents, and monitor lizards (Guishap) (d) and farm tools (e) [55].
