The first signs and symptoms of cryptosporidium infection usually appear within a week after infection and may include:

  • Watery diarrhea
  • Dehydration
  • Lack of appetite
  • Weight loss
  • Stomach cramps or pain
  • Fever
  • Nausea
  • Vomiting

Symptoms may last for up to two weeks, though they may come and go sporadically for up to a month, even in people with healthy immune systems. Some people with cryptosporidium infection may have no symptoms.

When to see a doctor

Seek medical attention if you develop watery diarrhea that does not get better within a few days.
