Transmission and infection of H5N1

Transmission and Infection of H5N1

The H5N1 is a subtype of the Influenza A virus that can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu, a type of influenza in birds. H5N1 is highly infectious and deadly, making it a type of virus that can potentially become a pandemic.

Transmission

The primary mode of human infection with H5N1 is through direct or indirect contact with infected live or dead poultry. The virus does not infect humans easily, and spread from person to person appears to be unusual. There is no evidence that the disease can be spread to people through properly prepared and thoroughly cooked food.

Infection

Once the H5N1 virus has infected a human, it can cause severe respiratory illness. Symptoms start off flu-like and deteriorate into potentially deadly pneumonia and acute respiratory distress syndrome.

Prevention and Control

Prevention and control of H5N1 infection in humans involves several strategies. These include vaccination, antiviral drugs, and pandemic preparedness.
