An epidemic study of molluscum contagiosum. Relationship to swimming

The incidence of molluscum contagiosum (MC) in children attending 15 public elementary schools and 9 kindergartens in Chigasaki City was studied by questioning their parents. Special attention was paid to the relationship between MC and swimming, and the incidence of MC in the swimming group was twice as high as that of the nonswimming group. This study also revealed that the predilection for lesions was the side of the trunk and the axillae.
