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

Insecticide-treated bed nets help reduce malaria transmission by providing a protective barrier against mosquito bites, especially during the night when mosquitoes are most active. By sleeping under an ITN, individuals are less likely to be bitten and thereby reduce their risk of contracting malaria.

ITNs are treated with long-lasting insecticides, which kill mosquitoes that come into contact with the net. These nets are highly effective in areas where malaria is prevalent, and their use has been shown to significantly decrease the incidence of malaria cases in communities that widely adopt this practice.
