The correct answer is Malaria. Malaria is caused by a protozoan parasite called Plasmodium.
How do protozoa cause disease in humans?
Pathology. Protozoal infection results in tissue damage leading to disease. In chronic infections the tissue damage is often due to an immune response to the parasite and/or to host antigens as well as to changes in cytokine profiles. Alternatively, it may be due to toxic protozoal products and/or to mechanical damage.

Ingestion of contaminated water causes the larvae to migrate from the intestines via the abdominal cavity to the tissue under the skin. The larvae mature and release a toxic substance that makes the overlying skin ulcerate. After treatment, symptoms disappear and the worms can be safely removed from the skin.
