Forty-two countries or territories have been certified as malaria-free by the World Health Organization (WHO). This has been attributed to efficient diagnosis and treatment for the parasitic condition, as well as the use of mosquito nets and insecticides.
But with climate change creating new breeding grounds for the mosquitoes that transmit malaria and the roll out of an effective vaccine too costly for many countries, eradicating malaria worldwide is not a straightforward task.
