Cyclospora outbreak up to 307 cases in Texas

The Texas Department of State Health Services announced on Wednesday that a Cyclospora outbreak that is being reported in 24 states caused 307 cases of cyclosporiasis in Texas this year.

Most of the cases had onsets in June and July and a majority of the cases were reported in the Dallas/Fort Worth area. The DSHS is looking into the cases to identify potential common exposures and to find out if they are connected to the outbreak in other states.

The state is reporting Cyclospora infections in multiple counties, including Wise, Williamson, Wharton, Walker, Victoria, Van Zandt, Uvalde, Travis, Tom Green, Tarrant, Smith, Potter, Parker, Orange, Nolan, Navarro, Montgomery, Montague, Matagorda, Kendall, Kaufman, Johnson, Jefferson, Hunt, Hood, Hidalgo, Henderson, Harris, Guadalupe, Grayson, Galveston, Fort Bend, Ellis, El Paso, Denton, Dallas, Coryell, Collin, Cameron, Brazoria, Bowie, Bell, Austin and Archer.

Nebraska and Iowa linked cases in their states to a bagged salad mix distributed to some restaurants. Past outbreaks of cyclosporiasis were connected with eating imported fresh produce. The DSHS recommends the thorough washing of fresh produce as a general precaution.

According to the U.S. Centers for Disease Control and Prevention, Cyclospora cayetanensis is a single-celled parasite that causes cyclosporiasis, an intestinal infection. There are 641 reported cases of the infection in 24 states.
