Epidemiology of Mexico virus, a small round-structured virus in Yorkshire, United Kingdom, between January 1992 and March 1995.

The epidemiology of the small round-structured virus, Mexico virus (MxV), was investigated in North and West Yorkshire, United Kingdom, between January 1992 and March 1995 using a type-specific antigen ELISA. The results indicate that an epidemic of MxV occurred during the winter of 1993-1994, when this strain was associated with 45 of 99 outbreaks and sporadic childhood cases of gastroenteritis. Only 4 MxV-like isolates were found during the 1992-1993 winter season and none in the 1994-1995 season. This descriptive epidemiologic study suggests that MxV has an epidemic pattern of infection.
