Human African Trypanosomiasis (HAT), also called African sleeping sickness, is a parasitic disease that is transmitted by infected tsetse flies. HAT can occur as a chronic or acute infection depending on the sub-species of parasite responsible for the infection.
Once the brain is affected it results in changes in behaviour, confusion, poor coordination, difficulties with speech and disturbance of sleep (sleeping through the day and insomnia at night), hence the term âsleeping sicknessâ. Without treatment, African trypanosomiasis is fatal. Screening and diagnosis of African trypanosomiasis is a parasitic disease transmitted by the tsetse fly. It gets its nickname âsleeping sicknessâ because symptoms can include a disturbed sleep pattern.
