Key Takeaways
- Over 1,000 cases of cyclosporiasis reported in Michigan
- More than 500 cases reported in Ohio
- No deaths have been reported, but hospitalizations have occurred
- The source of the infections has not been identified
A recent surge in cyclosporiasis infections has been reported across America, with Michigan being the hardest hit, having more than 1,000 people diagnosed. This is the largest outbreak of its kind in Michigan's history and one of the country’s largest in years. The infections have caused weeks of watery diarrhea, with symptoms including severe abdominal cramping, bloating, nausea, fatigue, and significant weight loss.
According to the Centers for Disease Control and Prevention (CDC), the hallmark symptom of a cyclospora infection is watery diarrhea that can last for weeks or even months if left untreated. Michigan officials announced the outbreak last week following the identification of more than 170 cases since June 22 in the southeastern part of the state. Typically, only about 50 cases are identified in Michigan each year.
Investigation and Precautions
The CDC, alongside the Food and Drug Administration and state health officials, is actively investigating several multistate clusters, but they have yet to find a cause behind the spread. Past infections have reportedly been linked to consuming contaminated fruits or vegetables, or being exposed to contaminated irrigation water. Fresh produce should be washed thoroughly before being eaten, although this may not eliminate the risk of infection.
Michigan officials recommend purchasing salad mixes or whole heads of lettuce instead of pre-washed, bagged lettuce. Remove two to three leaves from the outer layer of the lettuce head before washing and cook vegetables when possible. The official outbreak season for the parasite runs from May 1 through Aug. 31, a window where warmer temperatures historically coincide with a spike in infections.
Why This Matters
The cyclosporiasis outbreak is a significant public health concern, and it is essential for individuals to take precautions to prevent infection. By understanding the risks and taking steps to protect themselves, people can reduce their chance of contracting the illness and help prevent further spread.
