What is Cyclosporiasis caused by the Cyclospora outbreak?

Cyclospora is a foodborne parasite that can cause severe gastrointestinal illness. It has been linked in the past to fresh produce such as herbs, salad greens, and berries. According to the Cleveland Clinic, it causes watery, sometimes explosive diarrhoea and other stomach problems. Symptoms usually start within a week of ingesting the parasite. Left untreated, symptoms may take a long time to go away. Moreover, you’re at a greater risk of a severe infection if you have a weakened immune system.
