Outbreak of rash in children associated with recreational mud exposure.

We conducted an investigation of a rash outbreak in children who attended the "Mud Mania Festival." The mean incubation period of illness was 26 hours, and mean duration was 4.3 days. Time spent in mud was associated with the extent of rash in a dose-response fashion. The cultures from lesions of two unrelated cases yielded Enterobacter cloacae.
