What is rotavirus?
Rotavirus is a major infectious source of diarrhoea in foals. Foals are more susceptible to rotavirus due to an underdeveloped immune system. If treated, most foals make a full recovery, however rotavirus shedding can occur in recovered foals. Adult horses do not shed rotavirus.
At what age are horses at risk?
Rotavirus is seen predominantly in foals aged one week to five months.
How is rotavirus transmitted?
Equine rotavirus is transferred via the faecal-oral route.
Signs to look out for:
Most cases of rotavirus resolve without treatment. Foals with the virus present symptoms quickly and will stop nursing and become depressed with diarrhoea within 12-24 hours of infection.
