Ivermectin Applications in Malaria Transmission Control
Summary
Ivermectin, a broad‐spectrum endectocide long used against parasitic infections, has attracted interest as a complementary tool for malaria control owing to its capacity to render human and animal blood lethal to Anopheles mosquitoes. When ingested by vectors feeding on treated hosts, ivermectin reduces mosquito survival, impairs parasite development within the mosquito, and can diminish community‐level transmission. Strategies under evaluation include repeated mass drug administration to humans during transmission seasons, treatment of livestock to target zoophagic vectors, and optimised dosing regimens that balance safety, pharmacokinetics and entomological impact. By integrating ivermectin into existing vector control programmes—such as insecticide‐treated nets and indoor residual spraying—researchers aim to address residual outdoor transmission, insecticide resistance and heterogeneity in vector behaviour. Emerging evidence emphasises the need for finely tuned dosing schedules, consideration of drug–parasite–vector interactions and operational feasibility in diverse endemic settings.

Ivermectin Applications in Malaria Transmission Control publication trend
The graph below shows the total number of articles in ivermectin applications in malaria transmission control across all publications each year (not limited to Nature Index journals).
Technical terms
Endectocide: A drug active against both internal and external parasites of treated hosts, capable of rendering host blood toxic to blood-feeding vectors.
Mass drug administration (MDA): The distribution of therapeutic agents to an entire population or community subgroup, irrespective of individual infection status, to achieve a public health effect.
Sporogony: The developmental phase of Plasmodium parasites within the mosquito vector, culminating in formation of infectious sporozoites.
Asexual blood stage: The phase of the malaria parasite lifecycle in which merozoites invade and replicate within human erythrocytes, responsible for clinical disease symptoms.
