Summary Six outbreaks of equine influenza virus A 2 (EIVA 2 ) were diagnosed serologically at five different racetracks during 1983–84. EIVA 2 was isolated from horses at four outbreaks. Of the horses sampled, only horses which had not been vaccinated within six months became clinically ill. Clinically normal stablemates sampled during theseoutbreaks showed no serological evidence of subclinical infection. Thereappeared to be a correlation between hemagglutination inhibition (HI) titerand susceptibility to disease. Horses vaccinated biweekly appeared to have a statistically significantly higher EIVA 2 HI titer than those vaccinated tri-annually. Empirically, it was concluded that there had been no significant change in the antigenic components of EIVA 2 . |
