Constructing a causal model of African human trypanosomiasis. The Antwerp Trypanosomiasis Causal Modelling Group.

Following the TDR/WHO sponsored Workshop on Modelling Sleeping Sickness Epidemiology and Control, 25-29 January 1988, Antwerp, a group of scientists at the Institute of Tropical Medicine "Prince Leopold" (ITM), Antwerp, started to develop a causal model of human african trypanosomiasis. The group hypothesised a series of relations between determinants and associated factors of the prevalence of sleeping sickness. These relations were pictured in a logically structured hierarchial representation of the causal web of sleeping sickness.
