Cryptosporidiosis, 2017

During 2017, 481 cases of cryptosporidiosis (8.7 per 100,000 population) were reported. This is markedly higher than the median number of cases reported annually from 2007 to 2016 (median, 331 cases; range, 235 to 465). The median age of cases was 26 years (range, 6 months to 88 years). Children 10 years of age or younger accounted for 20% of cases. Fifty-five percent of cases occurred during July through October. The incidence of cryptosporidiosis in the Southwestern, Southeastern, Northwestern, and West Central districts (52.0, 18.0, 15.8, and 15.4 cases per 100,000, respectively) was significantly higher than the statewide incidence. Only 99 (21%) reported cases occurred among residents of the metropolitan area (3.3 per 100,000). Forty-seven (10%) cases required hospitalization, for a median of 4 days (range, 2 to 19 days). No deaths were reported.

Six confirmed outbreaks of cryptosporidiosis were identified in Minnesota in 2017, accounting for 22 laboratory-confirmed cases. Two recreational water outbreaks occurred, accounting for 28 cases (12 laboratory-confirmed). Both waterborne outbreaks were associated with municipal pools/aquatic centers in Redwood County. Three outbreaks due to person-to-person transmission at child care centers accounted for 21 cases (5 laboratory-confirmed); the outbreaks occurred in Renville (n=2) and Redwood Counties. One outbreak probably due to foodborne transmission at a private home resulted in 9 cases (5 laboratory- confirmed).
