Cyclosporiosis

 You’re referring to Cyclospora cayetanensis infection (often just called cyclosporiasis), which is caused by the parasite Cyclospora cayetanensis.



🦠 What it is



It’s a microscopic parasite that infects the intestines and causes gastrointestinal illness.



🚨 Symptoms



Symptoms usually start about 1 week after exposure and can include:


  • Watery diarrhoea (often prolonged or recurring)
  • Loss of appetite
  • Weight loss
  • Bloating and gas
  • Fatigue
  • Nausea (sometimes vomiting)



Without treatment, symptoms can last weeks or even months, often coming and going.



🥗 How you catch it



Cyclospora spreads through contaminated food or water, especially:


  • Fresh produce (like salad leaves, herbs, berries)
  • Food washed with contaminated water



It’s not usually spread directly person-to-person, because the parasite needs time in the environment to become infectious.



💊 Treatment



The standard treatment is an antibiotic:


  • Trimethoprim-sulfamethoxazole (often called co-trimoxazole)



Most people improve quickly once treated.



🧼 Prevention



  • Wash fruits and vegetables thoroughly
  • Be cautious with untreated water when travelling
  • Good kitchen hygiene





If you’re asking because of symptoms or a recent diagnosis, I can help you figure out what to watch for or when to seek care.
