Protozoa in Human Disease

Protozoa are single-celled organisms that can cause various diseases in humans. Some common diseases caused by protozoa include malaria, which is transmitted by mosquito bites, and giardiasis, often spread through contaminated water. These microorganisms can invade and damage body tissues, leading to symptoms like fever, diarrhea, and fatigue. Protozoal infections can be serious, particularly in weakened immune systems. Prevention mainly involves good hygiene practices, using insect repellent, and ensuring clean drinking water. Treatments vary depending on the specific protozoan but often include medications designed to eliminate the infection.
