Influenza A virus subtype H3N8

From Food & Medicine Encyclopedia

Influenza A virus subtype H3N8 is a subtype of the Influenza A virus that is known to cause illness in birds, horses, and dogs. It is a part of the Orthomyxoviridae family of viruses.

History[edit]

The H3N8 subtype was first identified in horses in the late 1960s. It was later found in dogs in the United States in 2004, marking the first time that the virus had been found in a species other than horses or birds. The Canine influenza outbreak of 2004 was caused by the H3N8 subtype.

Structure and Function[edit]

Like all Influenza viruses, H3N8 is an RNA virus. It has a segmented genome, meaning its genetic material is split into eight separate segments. This allows for genetic reassortment, a process that can lead to the creation of new virus strains.

Transmission[edit]

H3N8 is primarily transmitted through the respiratory route, via coughing or sneezing. It can also be spread through direct contact with infected individuals or contaminated surfaces.

Prevention and Treatment[edit]

Vaccines are available for both equine and canine H3N8. Antiviral drugs, such as oseltamivir, may also be used to treat infections.
