Cyclosporiasis Cases Rise to Over 2,800 in US Outbreak

State health officials in Michigan and Ohio have reported an outbreak of cyclosporiasis, a parasitic infection causing "watery diarrhea," loss of appetite, and weight loss, with cases now exceeding 2,800. This significant rise in reported illnesses occurred approximately one year after the Trump administration implemented funding cuts to state and local health departments. Additionally, a program focused on coordinating information regarding foodborne illnesses, including those caused by Cyclospora, saw its responsibilities reduced.

The parasitic infection, cyclosporiasis, is typically contracted through contaminated food or water. Symptoms can include frequent, watery bowel movements, fatigue, loss of appetite, nausea, vomiting, and stomach cramps. The Centers for Disease Control and Prevention (CDC) notes that symptoms can appear several days to a week after consuming contaminated food or water and can last for weeks or even months if left untreated. Treatment usually involves antibiotics.

While the specific source of this particular outbreak has not yet been definitively identified, health officials are investigating potential links to contaminated produce or other food products. Cyclosporiasis outbreaks have been linked to various fresh produce items in the past, including berries, herbs, and leafy greens. The reduction in funding and coordination for foodborne illness programs may hinder the speed and effectiveness of identifying and containing such outbreaks in the future.
