Hand, foot, and mouth disease is a common childhood illness that primarily affects children between the ages of 6 months and 6 years. It is rare for adults to become ill with this disease.
The course of the illness usually begins with mild cold symptoms (sore throat), occasional fever, irritability, and reduced appetite. After a couple of days, the rash appears, often consisting of small blisters on the hands, feet, and around or inside the mouth. Less commonly, the rash may also occur on the arms, buttocks, and genital area. The blisters have a reddish ring, easily rupture, and leave behind small sores and scabs (before the skin heals).
The childhood illness is caused by a virus known as coxsackievirus. This virus spreads through physical contact, droplets, andfeces. Feces can contain the virus for 4-6 weeks. Outbreaks often occur in childcare settings (typically late summer and autumn). It takes approximately one week from exposure to the virus to the onset of symptoms. The diagnosis is based on the appearance of the rash, and no testing is necessary.
The disease usually resolves on its own, and the skin and mucous membranes heal without scarring. Therefore, treatment is generally not necessary. The most important aspect is to ensure adequate food and fluid intake.
