BalancedA cyclospora outbreak is rapidly growing into a serious multi-state public-health problem, with case counts passing major milestones and hospitalizations mounting. The urgent takeaway is that this is not a routine stomach bug but a spreading parasitic illness affecting large numbers of people.
Symptoms And Protection
Mostly CenterCyclospora is a gut parasite that can cause severe, long-lasting diarrhea and is different from many common gastrointestinal illnesses. People need to know the symptoms, when to seek care, and the practical steps that reduce their risk of infection.
