What Are the Different Types of Parasitic Diseases?
Parasites are organisms which live on or in a host and get their food from the host. While there are thousands of known parasites, only about 100 affect humans. The problems caused by parasitic infections range from minor discomfort to serious diseases. The three types of parasites which affect people are protozoa, helminths, and ectoparasites. Some parasitic diseases will eventually disappear on their own, while others can cause disability or death if left untreated.
