The Complex Interplay of Malaria and EBV in Burkitt Lymphoma

Burkitt lymphoma (BL) is an aggressive B-cell lymphoma endemic in children in regions of sub-Saharan Africa, where its incidence geographically overlaps holoendemic Plasmodium falciparum malaria and poorly controlled childhood Epstein-Barr virus (EBV) infection. Despite decades of research, the precise mechanistic synergy between these two pathogens remains incompletely defined. This review synthesizes current epidemiological, immunological, and molecular evidence to propose an integrated model for the etiology of endemic BL. We outline a paradoxical, dual-edged relationship wherein EBV infection during infancy may provide a short-term child survival advantage against severe malaria while simultaneously increasing the long-term oncogenic risk in B-cells infected by EBV. P. falciparum infection triggers polyclonal B-cell activation, increasing the probability of an activation-induced cytidine deaminase (AID)-mediated c-MYC translocation in proportion to the recurrent parasite burden. Concurrently, EBV expands within this B-cell pool and modulates the host immune response, potentially through viral interleukin-10 (vIL-10), to prevent lethal malarial inflammation. At the cellular level, EBV provides a critical "second hit" when it establishes latency I infection that rescues c-MYC-translocated B-cells from apoptosis. This framework explains why BL manifests as a "tumor of malaria survivors," peaking in incidence years after the highest-risk period for malaria mortality. Ultimately, this model underscores that malaria control is a critical form of cancer control and highlights key future directions for validating these pathways in prospective clinical studies.
