Epidemiology
Equine adenovirus type I occurs worldwide,and seroprevalence rates vary from less than 2% to 100%,depending.on the serologic test used the age,breed,activity,and size of the population sample reported.The prevalence of antibody to EAdV1 increases with age sothat,in some populations,about 70% of yearlings and 2-year-old horses have EAdV1 antibody.Seorologic evidence indicates a high infection rate in the first year of life,but in some populations,50% of horses under 1 year lack EAdV antibody and are presumably at risk for EAdV disease.
