Cyclospora is a parasite that can cause gastrointestinal illness in humans. It is typically spread through contaminated produce or water and is more common in tropical and subtropical regions. Symptoms can include diarrhea, cramps, and fatigue, and can last for several weeks. Treatment typically involves antibiotics and hydration. It is important to practice good food and water safety habits, such as washing produce thoroughly and ensuring water sources are clean, to prevent the spread of cyclospora. If you suspect you have been infected, it is important to seek medical attention promptly.
