Cyclospora cases have been reported in several states. What to know about the diarrhea-causing parasite.
Michigan is currently facing its largest outbreak of a parasitic infection in state history, with nearly 1,000 people diagnosed with cyclospora. This infection can lead to weeks of watery diarrhea and has sparked investigations in 28 other states, including Ohio, where cases are also on the rise.
Cyclospora is a microscopic parasite that causes cyclosporiasis, a condition characterized by watery diarrhea and gastrointestinal discomfort. Outbreaks typically occur in the late spring and summer and are often linked to contaminated fruits and vegetables. While the source of the current infections in Michigan remains unknown, previous outbreaks have been associated with items such as bagged salad mixes, fresh cilantro, and raspberries.
The surge in cyclospora cases in Michigan is concerning, but it is not considered a national health emergency. The state has been proactive in investigating and reporting cases, which may be why it appears to be the hardest hit. The Food and Drug Administration and the Centers for Disease Control and Prevention are actively monitoring the situation and working with state partners to identify the source of the outbreak.
Symptoms of cyclosporiasis include diarrhea, loss of appetite, cramping, and fatigue. While most people recover without treatment, antibiotics can be prescribed for severe cases. Prevention measures include thorough washing of fresh produce and cooking vegetables when possible to reduce the risk of infection.
As investigations continue, Michigan officials recommend consumers purchase whole heads of lettuce over prewashed varieties and ensure proper washing before consumption. Cooking vegetables can also help eliminate potential sources of contamination. It is crucial for individuals experiencing persistent diarrhea to seek medical attention and discuss the possibility of cyclospora with a healthcare provider.
Overall, the current cyclospora outbreak serves as a reminder of the importance of food safety and vigilance in preventing the spread of parasitic infections. By following proper hygiene practices and staying informed about potential risks, individuals can protect themselves and their communities from cyclosporiasis.
