Influenza A virus subtype H10N3

Influenza A virus subtype H10N3 is a subtype of the Influenza A virus that is known to cause influenza in birds and humans. This subtype is one of many influenza A subtypes that have been identified. The H10N3 subtype is not commonly found in humans, with only a few cases reported worldwide.

Structure and Classification

The Influenza A virus is classified into subtypes based on two proteins on the surface of the virus: hemagglutinin (H) and neuraminidase (N). There are 18 known H subtypes and 11 known N subtypes. The H10N3 subtype is thus one of many possible combinations of H and N proteins.

Infection in Birds

H10N3 is primarily found in birds, where it can cause severe disease. It is particularly prevalent in wild birds and domestic poultry. The virus is transmitted between birds through direct contact with infected birds, or through contact with contaminated surfaces.

Infection in Humans

Human infections with H10N3 are rare, but have been reported. The first known case of human infection with H10N3 was reported in China in 2021. The patient was a 41-year-old man who had been exposed to poultry. He developed symptoms of influenza, including fever and cough, and was hospitalized. He recovered after treatment with antiviral drugs.

Prevention and Control

Prevention of H10N3 infection in humans involves avoiding exposure to infected birds and practicing good hygiene. Control of the virus in bird populations involves surveillance to detect outbreaks, culling of infected birds, and vaccination.
