This viral infection is seen all around the world. As it’s commonly seen children younger than seven years of age , the outbreaks are seen in day-cares, summer camps or within the family. These outbreaks are usually during the summer and early autumn.

The spread of the human enterovirus is mediated by oral ingestion of the shed virus from the gastrointestinal or upper respiratory tract of infected hosts, or via vesicle fluid or oral secretions. After ingestion, the virus replicates in the lymphoid tissue of the lower intestine and the pharynx and spreads to the regional lymph nodes.
