Influenza A virus subtype H1N2

Influenza A virus subtype H1N2 (H1N2) is a subtype of the Influenza A virus, which is the most significant of the three types of influenza viruses (A, B, and C) that infect humans and many other animals. H1N2 is a reassortant strain of H1N1 and H3N2 subtypes.

History

The H1N2 subtype was first identified in humans in 1988-1989 and has been identified in various pig populations around the world. The current strains of H1N2 are descendants of the 1918 H1N1 pandemic strain and the H3N2 strain that first emerged in humans in 1968.

Epidemiology

H1N2 is not as common as other subtypes of Influenza A virus, but it has caused infections in humans in various parts of the world, including North America, Europe, and Asia. The virus is typically spread from person to person through the air by coughs or sneezes, creating aerosols containing the virus.

Clinical Features

The symptoms of H1N2 infection are similar to those of other influenza virus infections and can range from mild to severe. They typically include fever, cough, sore throat, muscle aches, headaches, and fatigue.

Prevention and Control

Vaccination is the most effective way to prevent infection with influenza viruses, including H1N2. Antiviral drugs are also available that can be used to treat infection with H1N2.
