The SETA study, launched in 2015, is a continuation and expansion of data collection from the typhoid fever surveillance network established through TSAP, which evaluated the typhoid burden through standardized surveillance at 13 sites in 10 sub-Saharan African countries
SETA Plus surveillance and the studies coordinated with the THECA consortium will be closely aligned with related work being conducted by the Typhoid Vaccine Acceleration Consortium (TyVAC)
The study will continue to collect standardized data from five sub-Saharan African countries (Ghana, the Democratic Republic of the Congo, Nigeria, Madagascar and Burkina Faso), including additional information on invasive Salmonella infections, such as severe manifestations of the illness and socio-economic burden.
