Understanding Bird Flu: Origins, Mutations, and Protection Against Its Spread - Billy D Manus

The Origins of Bird Flu Bird flu, or avian influenza, is a highly contagious viral infection that primarily affects birds but has also been found in a growing number of mammals, including humans. The virus belongs to the influenza A family, with strains such as H5N1, H7N9, and H5N8 being the most well-known for causing severe illness. Bird flu was first identified in Italy in the early 1900s but has likely existed for centuries in wild bird populations. Wild waterfowl, such as ducks, geese, and swans, serve as natural reservoirs for the virus, meaning they can carry and spread it without showing significant symptoms. From these birds, the virus can spill over into domestic poultry, leading to outbreaks on farms and in backyard flocks. Over time, genetic mutations and re-assortment with other influenza viruses have allowed certain strains of bird flu to infect mammals, increasing the risk of transmission to humans. How Bird Flu Mutates Bird flu viruses are known for their ability to...
