What Is Cyclosporiasis?

Cyclosporiasis is an intestinal illness caused by the microscopic parasite Cyclospora cayetanensis, also known as Cyclospora.

 

People can become infected by consuming food or water that contains the parasite. Cyclosporiasis is not usually life-threatening.

How Does Cyclosporiasis Spread?

Spread

It is important to note that Cyclospora does not spread directly from one person to another. 

​

Cyclospora can spread when people consume food or drink that is contaminated with fecal (poop) matter. The most common routes of transmission are fresh produce including:

  • Bagged salad mixes and kits (pre-cut lettuce blends with romaine, iceberg, red cabbage, carrots, etc.)

  • Fresh cilantro (coriander leaves)

  • Fresh basil

  • Raspberries

  • Snow peas

  • Green onions (scallions)

​

It takes at least 1 – 2 weeks in the environment (outside the body) for Cyclospora to become infectious after passing in a bowel movement.

Treatment

The Centers for Disease Control and Prevention (CDC) outlines the following treatment options for Cyclosporiasis:

  • Cyclosporiasis is treated with sulfa-antibiotics such as Bactrim, Septra, or Cotrim.

    • If you are allergic to sulfa drugs, talk to your healthcare provider about other potential options.
