Period of Infectivity
This is the length of time a horse can spread the virus after being infected. It is a very important concept, because horses can still infect other horses after they have gotten over their own illness. Viruses that are shed for long periods of time after a horse gets better are much harder to control. Horses tend to be most infectious (i.e. shedding the most virus) in the first 24–48 hours after they develop a fever, but they can shed the virus for up to 7–10 days after their signs of illness disappear.
