H5N1

Influenza A (H5N1) virus – also called “H5N1 virus” – is an influenza A virus subtype that occurs mainly in birds, is highly contagious among birds, and can be deadly to them. H5N1 virus does not usually infect people, but infections with these viruses have occurred in humans.

What is Bird Flu (H5N1)?

Bird flu or avian flu is a highly contagious viral infection that is transmitted between birds and on rare occasions, from birds to humans.
