Protozoal infections

Protozoal infections are caused by tiny, single-celled organisms called protozoa, which can invade the body and cause illness. These microorganisms can spread through contaminated food, water, or contact with infected individuals or animals. Symptoms vary depending on the type of protozoa and the infection site but may include diarrhea, stomach pain, fever, or fatigue. Common examples include malaria, caused by Plasmodium parasites transmitted by mosquitoes, and amoebiasis, caused by Entamoeba histolytica. Proper hygiene, safe drinking water, and protective measures against vectors are essential for prevention. Treatment typically involves specific antiparasitic medications.
