The number of cases of the parasitic infection, Cyclospora, has increased further in Texas, according to state health officials.

Since the “surge” of cases were first reported on the Tarrant County Health Department Facebook page Monday, the tally of cases have increased by 23, bringing the total to 92.

Dallas County accounts for the most cases (17), or 18 percent of cases.

 The Texas Department of State Health Services (DSHS) says though a source has yet to be identified, past outbreaks have been traced to fresh imported produce. DSHS encourages people to wash produce thoroughly, though that may not entirely eliminate the risk because Cyclospora can be difficult to wash off.

Cyclosporiasis is a gastrointestinal illness caused by Cyclospora cayetanensis. Illness is caused by consuming contaminated food and water. Symptoms include: watery diarrhea, (with frequent, sometimes explosive stools), loss of appetite, weight loss, abdominal cramping/bloating, increased flatus, nausea, and prolonged fatigue. Vomiting, body aches, low-grade fever, and other flu-likesymptoms may be noted. If untreated, relapse may occur. Cyclosporiasis is treated with trimethoprim-sulfamethoxazole. For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
