Tell Me About Award:
Malaria transmission persists in Sahelian West Africa and is re-increasing since 2020. Transmission of Plasmodium falciparum parasite occurs mainly during the wet season, between July and November, and is largely absent from the dry, hot season. Characterizing the P. falciparum genetic diversity is key to understanding parasite transmission dynamics and addressing the following questions: Which individuals act as reservoirs during the dry season? Who transmits the parasite? How does population movement impact transmission? What is the impact of malaria control measures (such as bednets and chemoprophylaxis) on the parasite population? Answers will be crucial for the eradication of the disease.

In this context, we conducted in 2021-2022 a one-year cohort study in Kedougou district, Senegal (600 participants in 4 villages), and in Kati and Timbuktu districts, Mali (300 participants in 2 villages each). We aimed to characterize parasites infecting asymptomatic participants at the different seasons (dry season, onset and end of the high transmission season), and monitoring the occurrence of clinical episodes. We collaborated with Wellcome Sanger Institute’s MalariaGEN to barcode >600 clinical falciparum malaria episodes diagnosed by healthposts or community healthworkers and detected 952 P. falciparum infections by qPCR, currently undergoing barcoding.
This project aims to analyse the genetic structure of Plasmodium falciparum populations, in order to shed light on inter-individual and community transmission at the local scale (household, village) with a transdisciplinary approach integrating genetic epidemiology, geo-epidemiology and artificial intelligence.
The main goals are:
- to analyse the relationships between Plasmodium genotypes causing symptomatic and those detected in asymptomatic carriers
- to identify clusters of individuals infected by the same parasite lineage, and identify transmission chains
- to establish if genetic distance across pairs of samples (as measured by Fst or IBD) is driven by geographic distance, time between two samples, or obeys to more complex patterns.
After obtaining genetic distance and cluster parasites in lineages in collaboration with Antoine Claessens’ team in LPHI Montpellier, the postdoc will analyse genetic diversity and associated factors, then leverage AI methods to predict genetic distance and lineage clustering between pairs of samples using supervised and unsupervised methods.
