The case count of infections with the protozoan parasite, Cyclospora in Texas has increased by more than a dozen in the past few days, according to new data from Texas Department of State Health Services (DSHS).

As of Aug. 1, the cyclospora case tally has reached 124, up from 110 on Tuesday. Of the 31 counties reporting cases, Dallas and Tarrant counties have recorded the most with 27 and 14, respectively.

Cyclosporiasis is an intestinal illness caused by consuming food or water contaminated with the Cyclospora parasite. The major symptom is watery diarrhea lasting a few days to a few months. Additional symptoms may include loss of appetite, fatigue, weight loss, abdominal cramps, bloating, increased gas, nausea, vomiting and a low fever. Symptoms may come and go multiple times over a period of weeks.

Although no common exposure source has been identified yet, past outbreaks in the United States have been associated with imported fresh produce, including pre-packaged salad mix, raspberries, basil, snow peas and mesclun greens. A 2013 outbreak in Texas was linked, at least in part, to fresh cilantro from Puebla, Mexico.  For more infectious disease news and information, visit and “like” the Infectious Disease News Facebook page
