As of Monday, Texas has had 121 lab-confirmed cases since May 1, according to officials with theTexas Department of State Health Services.Officials toldHouston Public Mediathere have been 23 hospitalizations and that a source for the Texas cases, which were domestically acquired, has not yet been identified.

According to the Galveston County Health District, cyclosporiasis, or cyclospora, is typically spread by consuming contaminated fresh produce or contaminated food or water. It is not commonly spread directly from person to person.

Symptoms could include digestive issues, stomach cramps, nausea and low-grade fever. Officials said they usually begin around one week after exposure and can last up to several days or weeks if the illness is not treated.

Officials said they recommend washing fresh fruits and vegetables thoroughly before eating, cooking produce items like fresh basil, cilantro and lettuce and washing hands before preparing any food to prevent cyclospora.
