Today, April 25, it commemorates the World Malaria Day, a disease to which half of the world's population is exposed, some 3.5 billion people, as the World Health Organization (WHO) has warned today. The malaria or malaria causes about 800,000 deaths each year. Most people at risk and affected live in the poorest countries on earth.

For this reason, WHO has called for stronger efforts to effectively control the disease, and for new donors to join the World Alliance Against Malaria.

Malaria is caused by a parasite called Plasmodium, which is transmitted through the bite of infected mosquitoes and, once in the human body, multiplies in the liver and then infects red blood cells.

Between the most frequent symptoms of the disease are fever, headaches and vomiting, which usually appear between 10 and 15 days after the bite of the mosquito. If left untreated, malaria can endanger the patient's life in a short time, as it alters the blood supply to vital organs.

One of the main problems faced by health systems is that in many areas of the world the parasites have become resistant to some of the existing antimalarial treatments. For this reason, more and more, it is proposed to spread a fast and effective treatment with combinations of medications based on artemisinin, use of mosquito nets impregnated with insecticide by people at risk and the fumigation of the closed spaces with insecticides of residual action, in order to control the mosquito vectors.
