Concerning factors associated with incidence, in univariate analysis, baseline CD4 cell count at inclusion, considered as a dichotomic (threshold at 350 cells/mm3) or as a quantitative variable (p = 0.03) and having experienced symptomatic malaria (declarative data) at the beginning of the pregnancy (p = 0.001) were associated with confirmed or suspected malaria-related fever. This evidence concerns the gene CD4 and malaria.
