Understanding Avian Influenza

Avian influenza, or bird flu, is a viral infection that primarily affects birds but can occasionally spread to humans. The most common strain affecting humans is H5N1, though H7N7 and H7N9 have also been reported. The disease was first identified in humans in 1997 in Hong Kong among poultry workers. Wild birds are natural carriers of the virus, which spreads through their feces, saliva, and mucus. Human infection can occur through inhalation or contact with the virus through the eyes, nose, or mouth, potentially leading to severe pneumonia and death.
