From 2007 to 2016, there were 3,613 cases of cryptosporidiosis and 67 reported outbreaks of cryptosporidiosis in Minnesota. Of these 67 outbreaks, 27 (40%) were attributed to waterborne transmission, 23 (34%) were attributed to person-to-person contact, 14 (21%) were attributed to animal contact, and 3 (4%) were attributed to foodborne transmission.
During 2016, 465 cases of cryptosporidiosis (8.5 per 100,000 population) were reported. This is markedly higher than the median number of cases reported annually from 2006 to 2015 (median, 321.5 cases; range, 235 to 389). The median age was 21 years (range, 6 months to 94 years). Children 10 years of age or younger accounted for 33% of cases. Fifty-six percent of cases occurred during July through October. The incidence of cryptosporidiosis in the Southwestern, Southeastern, South Central, and West Central districts (33.4, 20.5, 21.0, and 15.5 cases per 100,000, respectively) was significantly higher than the statewide incidence. Only 92 (20%) reported cases occurred among residents of the metropolitan area (3.0 per 100,000).
