Hand, Foot and Mouth is a common infection among young children. We provide sound, expert advice about the signs and symptoms, treatments, risks and complications of hand, foot & mouth here.
What causes Hand, Foot and Mouth disease?
This is a relatively common virus infection that is not related to the hand, foot and mouth disease that occurs in cattle.
Hand, foot and mouth disease is usually caused by the coxsackie A16 virus and generally infects children under 10 and especially preschool children.
It gives symptoms of fever followed by a sore throat and then spots inside the mouth and red blisters on the palms and soles.
The virus can also infect older children and adults, where the illness tends to be milder.
The virus is very contagious and spreads through direct contact, saliva and through faeces. Outbreaks can take place where they are large groups of children or within families.
The incubation period is 3 to 7 days.
Hand, foot and mouth disease is most contagious during the first week of infection when there are spots or ulcers in the mouth. Spots in the mouth usually clear within 7 days and the rash within 10 days.
