Correct option is C
On 5 September 2016, the World Health Organisation (WHO) declared Sri Lanka as malaria-free. This recognition came after Sri Lanka reported no indigenous cases of malaria for three consecutive years, a requirement for certification. Sri Lanka's success in eradicating malaria is attributed to strong governmental action, a robust healthcare system, and timely intervention in detecting and treating cases.
Information Booster: Malaria is caused by parasites transmitted through the bites of infected mosquitoes. Countries are declared malaria-free by WHO after they achieve no local transmission for at least three years. Sri Lanka successfully utilized a combination of vector control, widespread distribution of insecticide-treated nets, and early detection to eradicate malaria from its population.
