Cryptosporidium parvum
Cryptosporidium parvum is a microscopic parasite that causes a diarrheal illness called cryptosporidiosis. It spreads through contaminated water, food, or surfaces, especially in environments with poor sanitation. The parasite infects the intestinal lining, leading to symptoms like watery diarrhea, stomach cramps, nausea, and dehydration. It can affect anyone but is particularly risky for young children, the elderly, and immunocompromised individuals. The infection usually resolves on its own within a few weeks, but severe cases may require medical treatment. Good hygiene, safe drinking water, and proper food handling are essential to prevent infection.
