Texas Cyclospora outbreak grows to 135 cases

Texas has had 32 new cases of Cyclospora infection since Jul 2, bringing the total in the state to 135, the Texas Department of State Health Services (TDSHS) said in an update today.

Cases of the gastrointestinal illness have surged in recent days, with 123 of the total coming in the past 2 weeks. Cyclosporiasis is caused by consuming food or water contaminated by the parasite, but so far no source has been identified in the outbreak.

The main symptom is watery diarrhea, which can last for days or even months. Last summer Texas reported 200 Cyclospora cases, some of which were tied to cilantro from Mexico's Puebla region, the TDSHS said.
