Influenza A viruses can be divided into sub-types on the basis of the antigenic reactivity of the surface glycoproteins‚ the haemagglutinin (H1-H16) and the neuraminidase (N1-N9) molecules (Fouchier et al.‚ 2005). Equine influenza (EI) is caused by two subtypes H7N7 and H3N8. Outbreaks due to H7N7 are limited as the isolation of the virus has not been reported since last two decades
