Cryptosporidiosis Statistics

From 2016 to 2025, there were 4,081 confirmed cases of cryptosporidiosis and 56 reported outbreaks of cryptosporidiosis in Minnesota. Of these 56 outbreaks, 18 were attributed to waterborne transmission, 22 were attributed to person-to-person contact, 10 were attributed to animal contact, 3 were attributed to foodborne transmission, and 3 were due to an unknown transmission route.

During 2025, 325 cases of cryptosporidiosis (5.7 per 100,000 population) were reported. 

The 325 confirmed cases of cryptosporidiosis (5.7 per 100,000 population) in 2025 were lower than the median number of confirmed cases reported annually from 2015 to 2024 (median, 403 cases; range, 232 to 574). The median age of confirmed cases in 2025 was 29 years (range, 7 months to 86 years). Children 10 years of age or younger accounted for 19% of cases. Fifty-seven percent were female. Of the 317 cases for which race was reported, 269 (85%) were white, 20 (6%) were Black, 14 (4%) reported being other or multiple races, 13 (4%) were Asian, and 2 (<1%) were American Indian. Six percent of the 317 cases for which ethnicity was reported were Hispanic. Fifty-six percent of cases occurred from July through October.

The incidence of cryptosporidiosis in the Northwest, Northeast, Southeast and Central districts (8.3, 8.0, 7.6, and 6.9 cases per 100,000, respectively) was significantly higher than the statewide incidence. Only 148 (46%) cases occurred among residents of the metropolitan area (4.7 per 100,000). Twenty-three (7%) cases required hospitalization, for a median of 4 days (range, 2 to 26 days).
