Abstract Sero-surveillance can monitor and project disease burden risk. However, SARS-CoV-2 antibody test results produce false positive results, limiting their efficacy as a sero-surveillance tool. False are associated with malaria exposure, understanding this association is essential to interpret from malaria-endemic countries. Here, pre-pandemic samples eight endemic non-endemic countries four continents were tested by ELISA measure Spike S1 subunit reactivity. Individuals acute infection...

ABSTRACT Arthritogenic alphaviruses such as chikungunya (CHIKV) and o'nyong‐nyong (ONNV) viruses have shown capacity to cause widespread epidemics, with recurrent sporadic outbreaks occurring throughout sub‐Saharan Africa. We analyzed the seroprevalence for CHIKV ONNV in 470 non‐febrile subjects from three regions Senegal (Sindia, 2018; Thies, Kedougou, 2022/2023) using retrospective samples. assessed presence of anti‐CHIKV IgG neutralizing antibody titers against via enzyme‐linked...
The use of artemisinin derivative-based combination therapy (ACT) such as artesunate plus amodiaquine is currently recommended for the treatment uncomplicated Plasmodium falciparum malaria. Fixed-dose combinations are more adapted to patients than regimens involving multiple tablets and improve compliance. A fixed-dose + (ASAQ) was recently developed. To assess efficacy safety this new define its optimum dosage regimen (once or twice daily) in P. malaria, a multicentre clinical study...
Molecular epidemiology using genomic data can help identify relationships between malaria parasite population structure, transmission intensity, and ultimately generate actionable to assess the effectiveness of control strategies. Genomic data, coupled with geographic information systems further clusters or hotspots transmission, genetic spatial connectivity, movement by human mosquito mobility over time space. In this study, we performed longitudinal surveillance in a cohort 70 participants...
Objective: To assess adverse effects of long-term highly active antiretroviral therapy (HAART), that is, lipodystrophy and metabolic disorders, in a cohort African patients. Methods: One hundred eighty HIV-1-infected patients treated with HAART for 4-9 years Dakar 180 age-matched sex-matched controls were enrolled. Regional subcutaneous fat changes assessed by physicians, fasting blood samples drawn. Centralization body was estimated using skinfold ratio, waist circumference, to hip ratio...
