Will getting hand, foot, and mouth disease twice lead to getting it a third time?

Patient's question:

March 28, 2014, May 3, 2014, fever, mouth ulcers, drooling

Doctor's answer:

Hello, the probability of this situation is relatively low. Antiviral drugs such as virazole and viramidine can be used. Hand, foot, and mouth disease may be combined with conditions such as myocarditis, encephalitis, and meningitis, and should be treated promptly with symptomatic therapy. It is also contagious.
Hand, foot, and mouth disease is an infectious disease caused by enteroviruses, primarily affecting infants and young children. It can cause blisters on the hands, feet, and mouth, and in some cases, complications such as myocarditis, pulmonary edema, and aseptic meningitis and encephalitis may occur. The disease is widely distributed with no obvious regional characteristics; it can occur in all seasons, with higher incidence in summer and autumn. This condition often presents as outbreaks followed by sporadic cases. During outbreaks, kindergartens and daycare centers are prone to collective infections, while clusters of cases can also occur in families. The disease is highly contagious with complex transmission routes, and can lead to large-scale epidemics in a short period of time.
