COUNTYWIDE — Fourteen cases of cyclosporiasis have been confirmed in Galveston County, and four additional cases are under investigation, according to the Galveston County Health District.

The health district said it is investigating the increase in cases of the foodborne illness, which is caused by the parasite Cyclospora cayetanensis.

Symptoms can include frequent watery diarrhea, stomach cramps, nausea, fatigue, loss of appetite, weight loss and a low-grade fever.

Health officials are urging residents to thoroughly wash fresh fruits and vegetables before eating them. People should also wash their hands with soap and water before preparing or eating food and after using the restroom.

Anyone experiencing prolonged diarrhea or other symptoms should contact a health care provider, the district said.

The Galveston County Health District said the investigation remains ongoing and additional updates will be provided as more information becomes available.
