My 13 month old had hand foot and mouth disease about 2 months ago. I had read some information stating that children normally don’t get hand foot mouth disease again once they’ve had it. I was very surprised to realize yesterday and then confirmed by our pediatrician that she has it again. Is this common to experience this multiple times in such a short period? This is not fun!!!

Factors That Increase the Chance for Infection or Disease
Everyone who has not already been infected with an enterovirus that causes HFMD is at risk of infection, but not everyone who is infected with an enterovirus becomes ill with HFMD.
HFMD occurs mainly in children under 10 years old but can also occur in adults. Children are more likely to be at risk for infection and illness because they are less likely than adults to have antibodies to protect them. Such antibodies develop in the body during a person’s first exposure to the enteroviruses that cause HFMD.
Note here:
Infection results in immunity to (protection against) the specific virus that caused HFMD. A second case of HFMD may occur following infection with a different member of the enterovirus group.
