Michigan health officials recently reported 2,640 cases of cyclosporiasis, an intestinal infection caused by the cyclospora parasite, marking a significant rise from previous figures. The outbreak, which began in May, has led to 44 hospitalizations in the state. While investigators suspect contaminated lettuce or salad greens, no specific supplier or grower has been definitively linked to the illness, according to the Michigan Department of Health and Human Services.
Understanding the Cyclospora Parasite and Transmission
Cyclosporiasis is a gastrointestinal illness caused by the cyclospora parasite. According to the U.S. Centers for Disease Control and Prevention (CDC), the infection often occurs through contaminated food or water. In the United States, past outbreaks have occurred with fresh food including bagged salad mixes and some herbs, Michigan said.
The infection follows a seasonal pattern, with the season running from May through August, according to the U.S. Centers for Disease Control and Prevention.
Did you know?
Symptoms of cyclosporiasis usually manifest within several days of eating the contaminated food.
Comparing State and Federal Surveillance Data
A discrepancy currently exists between Michigan’s reported figures and national counts. As of July 9, the CDC reported 843 laboratory-confirmed cases across 31 states, with 86 hospitalizations. The variance in numbers often stems from how data is collected: the CDC surveillance figures include only laboratory-confirmed cases reported by states, whereas state data may include both probable and confirmed cases.
Symptoms and Treatment Protocols
Infection with cyclospora results in a set of symptoms that can persist for weeks if left untreated. The primary indicators, according to the CDC, include:
- diarrhea
- fatigue
- stomach cramps
- nausea
If not treated, the illness may last from a few days to a month or longer. A notable characteristic of this infection is that it may recur after symptoms initially subside, according to the CDC.
