Signs and symptoms

People experience symptoms of cyclosporiasis about one week (ranging as soon as 2 days – 2 weeks or more) after consuming food or drinking water containing Cyclospora. Some people who are infected, particularly people from areas where cyclosporiasis is endemic (regularly occurring within an area or region), may not have any symptoms.

Symptoms of cyclosporiasis may include

  • Watery diarrhea (most common)
  • Loss of appetite
  • Weight loss
  • Cramping
  • Bloating
  • Increased gas
  • Nausea
  • Fatigue

Less common symptoms may include

  • Vomiting
  • Body aches
  • Headache
  • Low-grade fever
  • Other flu-like symptoms

Without treatment, symptoms can last anywhere from a few days to a month or longer. Some symptoms, such as diarrhea, may go away and then return. Other symptoms, such as fatigue, may continue after the gastrointestinal symptoms have stopped.
