Cryptosporidiosis, 2018

In 2018, 532 cases of cryptosporidiosis (9.54 per 100,000 population) were reported. This is markedly higher than the median number of cases reported annually from 2008 to 2017 (median, 342 cases; range, 235 to 481). The median age of cases in 2018 was 23.5 years (range, 3 months to 92 years). Children 10 years of age or younger accounted for 22% of cases. Sixty percent of cases occurred during July through October. The incidence of cryptosporidiosis in the Southwestern, Southeastern, South Central, and West Central districts (31.8, 26.2, 19.2, and 14.5 cases per 100,000, respectively) was significantly higher than the statewide incidence. Only 142 (27%) cases occurred among residents of the metropolitan area (4.6 per 100,000). Fifty-six (11%) cases were hospitalized, for a median of 4 days (range, 2 to 31 days). Three deaths were reported.

Fourteen confirmed outbreaks of cryptosporidiosis were identified, accounting for 34 laboratoryconfirmed cases. Five recreational water outbreaks of cryptosporidiosis occurred, accounting for 108 cases (15 laboratory-confirmed). Three occurred at campgrounds (Goodhue, Le Sueur, and Waseca Counties), one was associated with a splash pad (Carver County), and one occurred at a municipal pool (Nicollet County). Two outbreaks associated with animal contact accounted for 8 cases (5 laboratory-confirmed); these outbreaks occurred in Rock and Stevens Counties. Seven outbreaks due to person-to-person transmission at child care centers accounted for 30 cases (14 laboratory-confirmed); the outbreaks occurred in Blue Earth (n=2), Kandiyohi (n=2), Carver, Fillmore, and Stearns Counties.
