The US outbreak of cyclospora, a parasite that can cause prolonged watery diarrhea, has surpassed 2,800 reported cases. Health officials say infections have been detected across several states, with new numbers expected to rise as testing and case reporting continue. The illness can last for days or weeks and may cause dehydration, especially in vulnerable groups. Officials urge people to follow food-safety guidance, stay alert for symptoms, and seek medical care if illness develops.
