Greek: kyclos = spherical, round; sporos = spore, capsule, semen; cayetanensis = Caribbean origin.
Worldwide (in warmer countries) several 100,000 persons are infected. Probably all had been infected abroad from their homes during holidays. The species name was given since the first description was done based on material of a patient who came from a Caribbean island.
Symptoms of Disease
Immunocompromised and immunocompetent persons show identical symptoms of disease, since both groups suffer for 2–9 weeks from diarrheas that appear watery and are produced three to four times per day. These diarrheas may disappear also without treatment, but affected persons are hit by weakness and abdominal pain.
Oral uptake of sporulated oocysts within fecally contaminated food or within drinking water.
Avoid potentially contaminated food or drinking water.
Two to seven days.
About 1 week.
Immunocompetent persons: 2 weeks; immunocompromised persons: up to 7–12 weeks.
Not necessary in persons with light symptoms. In cases of severe diarrheas cotrimoxazole (2 × 800 mg sulfamethoxazole/160 mg trimethoprim daily for a week) showed clearance of symptoms. Diarrheas of children were stopped within 4 days by application of 5 or 25 mg cotrimoxazole per kg body weight for 3 days.
