How did the disease "trypanosomiasis" get its name? Is it a parasite like malaria?

See below. African trypanosomiasis, also known as "sleeping sickness, " is caused by microscopic parasites of the species trypanosoma brucei. It is transmitted by the tsetse fly (glossina species), which is found only in rural africa. Although the infection is not found in the United States, historically, it has been a serious public health problem in some regions of sub-saharan africa.
