Indoor residual spraying (IRS) is a vector control intervention where insecticides are applied to the interior walls and ceilings of homes to kill mosquitoes and other disease vectors. It is a crucial strategy in reducing the transmission of malaria and other vector-borne diseases, especially in endemic regions.

Disease vectors are organisms that transmit pathogens and parasites from one infected host to another, playing a crucial role in the spread of infectious diseases. Understanding their biology, ecology, and control mechanisms is essential for effective disease prevention and management strategies.

Strategy in reducing transmission

Transmission of malaria

Vector-borne diseases are illnesses caused by pathogens and parasites transmitted to humans and other animals through vectors such as mosquitoes, ticks, and fleas. These diseases pose significant public health challenges due to their widespread nature, potential for outbreaks, and the influence of environmental and socio-economic factors on their transmission dynamics.

Vector-borne Diseases

Endemic regions are geographical areas where a particular disease is consistently present and maintained at a baseline level without external inputs. Understanding endemic regions is crucial for public health planning, resource allocation, and implementing targeted interventions to control disease spread.
