Parasitic Diseases

An infectious illness brought on by parasites is referred to as a parasitic sickness, commonly known as parasitosis. [Reference required] Organisms known as parasites feed off of their hosts while harming them. Parasitology is the study of parasites and parasitic illnesses. Helminths, parasitic arthropods, and parasitic protozoa are the three main categories of parasites that medical parasitology studies. Thus, diseases brought on by pathogens from either the animal world or the protozoan kingdom are referred to as parasitic diseases. Although bacteria and other organisms can operate as parasites, the phrase "parasitic illness" is typically used in a more narrow sense. Protozoa, which may infect other creatures with protozoa, helminths, which can cause helminthiasis, and ectoparasites are the three primary types of organisms that cause these illnesses.
