    How do you get a protozoan parasite?

    Protozoan infections are caused by single-celled parasites called protozoa. When these parasites are introduced to the body they multiply, interfere with the body’s normal functioning, and cause damage to vital organs. Protozoa usually enter the body either through an insect bite or through infected food or water.
