An outbreak of Cyclospora infection has been reported across 45 U.S. states, resulting in two confirmed deaths and thousands of illnesses. Utah alone has reported 48 cases this year, highlighting the widespread nature of the outbreak. The Centers for Disease Control and Prevention (CDC) and the Food and Drug Administration (FDA) have issued guidance to help the public prevent infection.
- The Cyclospora parasite causes an intestinal illness that can lead to severe diarrhea, fatigue, and other gastrointestinal symptoms. The parasite is typically spread through contaminated food or water. While the specific source of this current outbreak has not yet been identified, health officials are investigating common food items that are often implicated in such outbreaks, such as fresh produce.
- Symptoms of Cyclospora infection can appear several days to weeks after consumption of contaminated food or water. These symptoms can include diarrhea, loss of appetite, weight loss, stomach cramps, bloating, gas, nausea, and fatigue. Some individuals may experience vomiting.
- The CDC and FDA recommend thorough handwashing with soap and water, especially after using the toilet and before preparing or eating food. They also advise washing fresh fruits and vegetables thoroughly under running water, even if they will be peeled. Cooking food to appropriate temperatures can also help kill the parasite.
- Individuals experiencing symptoms consistent with Cyclospora infection should consult a healthcare provider for diagnosis and treatment. Prompt medical attention can help manage symptoms and prevent complications, particularly for vulnerable populations.
