During 2004, 147 confirmed cases of cryptosporidiosis (3.0 per 100,000 population) were reported. This is similar to the 155 cases reported in 2003 but represents a 21% decrease from the median number of cases reported annually from 1996 to 2003 (median, 185 cases; range, 81 to 242). The median age of case-patients in 2004 was 24 years (range, 6 months to 87 years). Children 10 years of age or younger accounted for 30% of cases. Forty-five percent of cases occurred during July through October. The incidence of cryptosporidiosis in the Southwestern, Southeastern, and South Central districts (9.1, 6.3, and 5.7 cases per 100,000 population,respectively) was significantly higher than the statewide incidence. Only 21 (14%) reported cases occurred among residents of the Twin Cities metropolitan area (0.8 per 100,000 population). Thirty-six (24%) case-patients required hospitalization, for a median of 3 days (range, 1 to 34 days). Two case-patients were known to be HIV-infected. No outbreaks of cryptosporidiosis were identified in 2004.
