Disease vectors are living organisms, typically arthropods such as mosquitoes, ticks, fleas, sandflies, and triatomine bugs, that biologically or mechanically transmit pathogenic agents between hosts, thereby enabling the spread of infectious diseases within populations and ecosystems. In vector-borne disease systems, pathogens often undergo essential developmental or replication stages within the vector (biological transmission), or are passively carried on contaminated body parts (mechanical transmission). Research on disease vectors encompasses their ecology, population dynamics, host-feeding behavior, vector competence, insecticide resistance, and interactions with environmental and climatic factors, informing surveillance, risk modeling, and integrated vector management strategies for disease control.
More than half a million people, the vast majority being children under the age of 5, die annually due to malaria, with Sub-Saharan Africa as the most highly burdened region. Mosquitoes belonging to the genus Anopheles carry ...
