🌿 Overview
Cryptosporidiosis is caused by Cryptosporidium parvum, a protozoan parasite spread through contact with infected people, animals, or contaminated food and water.

- Watery diarrhea
- Abdominal pain
- Fever, nausea, and vomiting
- Symptoms develop about 1 week after infection
- Usually lasts 7–10 days in healthy individuals
- In HIV patients: chronic symptoms, severe malnutrition, and dehydration
