Pathogenesis (disease development)
Trypanosomes multiply around the intestines of insects. They are shed by feces (stool) during sucking and enter the host by smear infection. Human-to-human transmission is possible transplacentally (through the placenta), through blood transfusions, or organ transplants.
Etiology (causes)
Biographic causes
- Affected mainly the rural population, aid workers.
Tourists are usually not affected during organized trips
