This node will be conducted in Cameroon, RoC , DRC and Gabon. RoC will learn from regional Cameroonian partners to conduct cross sectional studies, and Northern partners will transfer novel molecular diagnostics methods. This will be achieved through :

- Identification of comorbidities (NTDs + TB/HIV/Malaria) and investigations related to prevalence of soil transmitted helminthes and other NTDs in Congolese school children

- Cameroon and Gabon will investigate NTDs as comorbidities in samples collected from drug-drug interaction studies

- DRC will investigate NTDs as comorbidities in samples collected from children with malaria (PYRAMAX study)
