Sri Lanka has been declared malaria-free by the World Health Organisation in September 2016. However, imported cases are still a continuous threat to the country.
Malaria is a mosquito borne parasitic disease caused by the protozoan Plasmodium. The mosquito that transmits this disease belongs to the genus Anopheles. Malaria is a potentially life-threatening disease that carries a poor prognosis with a high mortality if untreated, but it has an excellent prognosis if diagnosed early and treated appropriately.
The disease is mostly a problem in developing countries with warm climates. Most malaria infections cause symptoms like the flu, such as a high fever, chills, and muscle pain. Symptoms tend to come and go in cycles. Some types of malaria may cause more serious problems, such as damage to the heart, lungs, kidneys, or brain. These types can be deadly.
