Other flies namely Tabanus, Haematopota, Lyperosia, Stomoxys spp. and Ornithodorus ticks are also involved in transmission of different species of Trypanosoma. Transmission also occurs through abrasion, wounds, mucous membranes or conjunctiva from contaminated faeces of flies or through blood transfusion from infected person. Congenital transmission and laboratory borne infections also recorded.


The disease starts with painful in duration and rise in temperature with chills, headache and nausea. Stiff neck, paralysis, lymphedenopathy, hepatosplenomegaly, anaemia, myocarditis, meningoencephalitis and conjunctivitis are other consequences of infection.Trypanosomes can be demonstrated in blood smears or in lymph and cerebrospinal fluid. Guinea pig, mice and rat are used isolation of organisms. Serodiagnosis is done by complimentary fixation test, agglutination test, ELISA and immunofluorescence assay. Control of vectors and use of protective clothing and net may help in prevention of disease.
