What is Rotavirus?

Rotavirus is an organism that is a major infectious source of equine diarrhoea, causing about 1 in 4 cases of diarrhoea in foals.1

When rotavirus enters the digestive system, the organism replicates and damages the lining of the intestines.2

It most commonly affects foals under the age of 6 months, especially if their mother has not been vaccinated against rotavirus.2
