What cause hand foot and mouth disease and how is it prevented and treated


Hand foot and mouth disease is a viral disease caused usually by the coxsakievirus A 16 and the enterovirus 71 (EV71). Coxsakievirus belongs to the picornaviridae family. Other than the above mentioned strains of coxsakievirus and enterovirus other strains of these viruses may also lead to hand foot and mouth disease.
The most common source of infection is through direct contact with different body secretions and fluids of the infected person.
Hand, foot and mouth disease is common in kindergarten and day care centers as there is repeated diaper change and potty training. Also the risk in small children is increased as they frequently put their hands in mouth.
The infectivity of the affected child is the highest during first week of infection although the child may remain infectious as the virus may be present in her body for weeks.
Adults are also sometimes responsible for transmitting the disease.
In the US usually outbreaks of hand, foot and mouth disease typically occur during summer and autumn seasons however in the tropical countries the disease can occur any time.

4. Avoid salty or spicy foods, eating soft solid food which require less chewing and washing of mouth with warm water.
