LITTLE ROCK — The Arkansas Department of Health (ADH) reports a rise in cyclosporiasis cases, with 277 confirmed infections statewide as of Tuesday, Aug. 18.

The majority of cases are concentrated in the northwest part of the state. Benton County leads with 160 confirmed cases, followed by Boone County with 26, Washington County with 24, and Carroll County with 11. In Northeast Arkansas, other counties are reporting fewer than 10 cases each.

The ADH noted that while cyclospora infections generally increase in spring and summer, the number of cases this year is higher than usual. An ongoing multistate outbreak has been linked to the rise, according to the department. Federal health officials have connected the outbreak to iceberg lettuce, as detailed in a July 2026 investigation by the Food and Drug Administration.

Cyclospora is a microscopic parasite that spreads through the ingestion of food or water contaminated with feces. Symptoms of an infection usually appear one to two weeks after exposure and include watery diarrhea, sometimes accompanied by explosive bowel movements.

The ADH advises the public to take precautions to reduce their risk, including:

- Washing all fruits and vegetables thoroughly before eating them. - Washing hands, kitchen utensils, and food preparation surfaces regularly. - Storing produce at recommended temperatures.

More details are available on the Arkansas Department of Health website and the Centers for Disease Control and Prevention's Cyclosporiasis Outbreaks and Investigations page.

Arkansas residents with concerns or symptoms are urged to contact their healthcare provider or a local health unit for testing and treatment. Individuals experiencing severe symptoms should seek medical attention promptly.
