  Cyclospora cayetanensis is a parasite that is so small it can only be seen under a microscope. When people eat food or drink water thats contaminated with Cyclospora, they can get an intestinal illness called cyclosporiasis. […] The time between becoming infected and becoming sick is usually about one week. Cyclospora infects the small intestine (bowel) and usually causes watery diarrhea, with frequent, sometimes explosive, bowel movements. Other common symptoms include loss of appetite, weight loss, stomach cramps/pain, bloating, increased gas, nausea, and fatigue. People may also experience vomiting, body aches, headache, low-grade fever, and other flu-like symptoms. Some people who are infected with Cyclospora do not have any symptoms. If not treated, the illness may last from a few days to a month or longer. Symptoms may seem to go away and then return one or more times (relapse). Its common to feel very tired.

  Cyclospora infects the small intestine, typically causing a range of gastrointestinal symptoms such as; profuse watery diarrhea, sometimes explosive bowel movements, and abdominal cramping. […] Other symptoms can also include nausea, fatigue, low-grade fever, anorexia, and weight loss. […] In more severe disease mucus or blood can be found in the stool which occurs most commonly in infants, the elderly, and immunocompromised patients such as those living with HIV/AIDS. Symptoms in these hosts can include acalculous cholecystitis. Guillain-Barré syndrome, ocular inflammation, reactive arthritis, and sterile urethritis have also been reported. […] Travelers from non-endemic countries are likely to experience more severe infection. Prolonged diarrhea can result in dehydration and malnutrition and may infrequently result in death, particularly in infants and individuals with other infections or co-morbidities. […] Healthcare providers should consider Cyclospora as a potential cause of prolonged diarrheal illness, particularly in patients with a history of recent travel to Cyclospora-endemic areas.

  Cyclospora cayetanensis, a coccidian parasite, can cause gastrointestinal illness in humans and is characterized by watery and persistent diarrhea and abdominal pain. Diarrhea (45.8%), abdominal pain (39.6%), and vomiting (18.8%) were the most frequent symptoms of cases with cyclosporiasis. […] The clinical presentation most frequently associated with cyclosporiasis includes diarrhea, weight loss, abdominal distension, nausea, vomiting, abdominal pain, flatulence, and fever. In the present study, diarrhea was most commonly reported, which is consistent with other studies worldwide. […] Eosinophilia (48%) was observed in 53% of 17 cases of cyclosporiasis in our study.

Diagnosis can be difficult because even patients who are symptomatic might not shed enough of the parasite in their stool to be detectable by lab examinations. Identification of the parasite requires special tests that are not usually done when stool is tested for parasites. Therefore, if indicated, healthcare providers should specifically request testing for cyclosporiasis.
