Protozoan diseases

Protozoan diseases are illnesses caused by tiny, single-celled organisms called protozoa. These microorganisms can invade humans through contaminated water, food, or insect bites, leading to symptoms like fever, diarrhea, or fatigue. Diseases such as malaria, caused by Plasmodium, and amoebic dysentery, caused by Entamoeba histolytica, are common examples. Protozoan infections can be serious but are often preventable through good hygiene, clean water, and mosquito control. Treating these diseases usually involves specific medications that target the protozoa, helping to cure the infection and prevent complications.
