Explain ONE control measure for malaria. - HSC - SSCE Biology - Question 21 - 2015 - Paper 1

Insecticidal bed nets provide a physical barrier against mosquito bites, thus preventing the transmission of the malaria parasite from infected mosquitoes to humans. These nets are treated with insecticide, which also kills mosquitoes that come into contact with the net.

The use of insecticidal bed nets has been shown to significantly reduce malaria incidence in populations at risk. They are especially important in areas where malaria is endemic, as they provide a cost-effective means of prevention, particularly for vulnerable groups such as children and pregnant women.
