Influenza A virus subtype H5N2

Influenza A virus subtype H5N2 is a subtype of the Influenza A virus that primarily affects birds, but can also infect humans. It is a subtype of the species Influenza A virus of the genus Influenzavirus A in the family Orthomyxoviridae.

Overview

The Influenza A virus is a single-stranded RNA virus that is categorized into subtypes based on two surface proteins: Hemagglutinin (H) and Neuraminidase (N). The H5N2 subtype is one of many possible combinations of these two proteins.

In Birds

In birds, H5N2 is highly pathogenic and can cause severe disease and death. The virus is spread through direct contact with secretions from infected birds, especially their droppings. It can also be spread indirectly through contaminated equipment and materials.

In Humans

Human infections with H5N2 are rare, but have occurred. Most human cases have been associated with direct or indirect contact with infected birds or their environments. Human infections with bird flu viruses can happen when enough virus gets into a person’s eyes, nose or mouth, or is inhaled.

Prevention and Control

Prevention and control of H5N2 in birds and humans involves surveillance, early detection and reporting, biosecurity measures, and vaccination.
