• Caused by a parasitic protozoa (single celled animal) called cryptosporidium parvum.
  • Incubation period is 2 – 10 days, so you may not start to show symptoms until after you return home.
  • Symptoms include diarrhoea, abdominal pain, nausea, vomiting, dehydration, fever, headaches and weight loss. Some infected people display no symptoms and do not appear to be ill.
  • Diagnosis of infection can be made through laboratory testing of a stool sample.
  • Can lead to long term symptoms of Irritable Bowel Syndrome and Chronic Fatigue Syndrome.
  • Transmitted via the faecal - oral route, usually in water. For example if someone has an "accident" in the pool and then you swallow the contaminated water.
