How many times can you get hfmd?

Sadly, you can get HFMD more than once, as HFMD is caused by several different viruses, including coxsackieviruses A5, A9, A10, A16, B1, B3, enterovirus 71, foot-and-mouth disease virus, and herpes simplex. The vast majority of cases, however, are caused by coxsackievirus A16.  http://www.drgreene.com/qa-articles/catch-handfootandmouth-disease/ A child with a healthy immune system will form antibodies to whichever virus caused the infection. If your son is re-exposed to the same virus, he will probably not be re-infected. He is still susceptible, in varying degrees, to the other viruses.  These highly contagious infections can spread through secretions such as saliva and feces. Do practice highest hygiene levels when your child is outside, e.g. clean hands with soaps, never put hands into mouth, avoid crowded places and etc.

A child can get hand foot and mouth disease again after getting it once. Like flu, there are different strains of HFMD, so the baby will not be immune to the virus after having it once. It is also highly contagious since it can easily spread through body fluid. The first sign is usually fever (and not the rashes). Practice good hygiene to avoid catching it.

You can get it multiple times. It's not a one time thing. Just like viral infections. Your lo can get it again if it spreads. In fact it can happen to anyone.

You can't catch the same strain twice, but there are many strains - so technically you can get it multiple times . :(
