Sleeping Sickness at the Crossroads

Estimating and Mapping the Population at Risk of Sleeping Sickness

BACKGROUND Human African trypanosomiasis (HAT), also known as sleeping sickness, persists as a public health problem in several sub-Saharan countries.

Sleeping sickness – human African trypanosomiasis

Sleeping sickness and the central nervous system.

Chronic African trypanosomiasis is associated with progressive behavioural deficits, for which there is a complex underlying central nervous system (CNS) pathology. This has been extensively studied in man and a range of experimental animals. An initial meningitis, which can occur quite early in the infection, is followed by a breakdown of the choroid plexus, movement of the parasite into certa...
