A parasite that causes intestinal trouble like diarrhea, cramps and bloating is spreading nationwide this summer, but Virginia’s Department of Health said this week there is no evidence to suggest an outbreak in the state.
There were 37 confirmed cases of cyclosporiasis as of July 4, officials said. Cyclospora, the microscopic parasite that causes it, is transferred to humans through contaminated fruits and vegetables. Authorities are still trying to pinpoint the source.
VDH risk communications manager Brookie Crawford said that washing fruits and vegetables under running water before eating, cutting, or cooking can help prevent the illness. She added that thorough handwashing also helps.
As of this week the Centers for Disease Control and Prevention reported 1,645 known cases of cyclosporiasis, with 141 hospitalizations from it and no deaths. The CDC website noted that it is aware of 5,100 cases that may require further analysis to confirm whether they stem from cyclosporiasis.
“So far this year, multiple states have reported an increase in cases compared to the same period in 2025,” the CDC website reads.
Symptoms, which also include nausea and fatigue, typically begin about a week after exposure. Less common symptoms may include low-grade fever and vomiting. If left untreated, symptoms may last from a few days to a month or longer, the CDC said.
Cyclosporiasis is an intestinal infection and a seven to 10 day course of antibiotics can treat the illness. People living with HIV may need a longer course of therapy as their immune systems are already compromised.
