HIV and Malaria Coinfection Dynamics
Summary
HIV and malaria coinfection represents a major health challenge in regions where both pathogens are endemic, notably sub-Saharan Africa. The overlapping distributions of Plasmodium species and HIV lead to frequent dual infections, which can mutually exacerbate disease severity. HIV-induced immune suppression, marked by declining CD4+ T cell counts, increases susceptibility to clinical malaria, heightens parasitaemia and prolongs parasite carriage. Conversely, malaria triggers systemic inflammation and CD4+ T cell activation, creating a favourable environment for HIV replication and raising viral load. These bidirectional interactions accelerate progression of both conditions and complicate management, especially in resource-limited settings. Antiretroviral therapy (ART) and antimalarial interventions must therefore be carefully integrated to optimise patient outcomes. Understanding the immunopathogenic mechanisms underlying coinfection, including shifts in neutrophil function, cytokine profiles and gastrointestinal barrier integrity, is essential for the development of targeted therapies. Concurrently, epidemiological studies of gametocyte production and transmission dynamics inform public health strategies aimed at reducing onward spread of both diseases. Advances in prophylaxis, vector control and vaccine development hold promise for alleviating the dual burden, but coordinated regional programmes remain indispensable.
