The first signs and symptoms of cryptosporidium infection usually appear within a week after infection and may include:
- Watery diarrhea
- Lack of appetite
- Weight loss
- Stomach cramps or pain
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.
