The mystery illness that has killed at least 52 children in Cambodia since April has been diagnosed as hand, foot and mouth disease ,according to the World Health Organization.

The virus, known as EV-71, is spread by sneezing, coughing and coming into contact with fluid from blisters or faeces from someone who is infected.

Hand, foot, and mouth disease is not related to the animal disease known as foot-and-mouth, Health officials say the two are caused by different viruses.
