MORE ABOUT MALARIA
What is malaria?
Malaria is the collective name of a potentially fatal group of diseases caused by parasitic organisms spread through bites of a particular mosquito.
Symptoms of malaria include periods of fever, chills, and sweating followed by respiratory problems and organ failure and, finally, death. Malaria is preventable and, if it’s caught early, it is curable.
Malaria is caused by a parasitic, microscopic organism known as a protozoan. At least four members of the genus Plasmodium are known to cause malaria in humans. These are P. falciparum, P. malariae, P. ovale, and P. vivax. P.knowlesi may also cause malaria.
These protozoa enter the bloodstream through a bite from several different species of female mosquitoes from the genus Anopheles. The protozoa are more likely to live inside a mosquito with a long life and are more likely to enter humans if the mosquito has a tendency to bite humans instead of animals.
The majority of species of Anopheles mosquitoes that fit both categories are native to Africa. For this reason, over 90 percent of the world’s malaria cases occur in Africa. In 2018, there were 228 million cases of malaria, with 405 thousand deaths.
Why is malaria important?
The first records of the word malaria come from around 1730. It is a contraction of the Italian mala aria, meaning “bad air.” People once thought malaria was caused by poisonous air, but we now know this is not true.
Children under 5 years old are the most at risk of dying from malaria. This age group alone accounted for 274,000 (67 percent) of malaria deaths in 2018.
The biggest factor in the infection rate of malaria is the number of mosquitoes that spread the protozoa. Climate and rainfall have a large impact on the survival of the mosquitoes, so weather patterns actually play a big role in how many people are likely to be infected with malaria. Being repeatedly bitten by these mosquitoes can also lead to a partial immunity to the disease, which is why young children who have never been bitten are most vulnerable.
Did you know … ?
The fact that malaria is caused by protozoa spread by mosquitoes was discovered by British surgeon Sir Ronald Ross. Ross dedicated much of his life to the prevention of malaria and was awarded the Nobel Prize in Medicine in 1902 for his work. In addition to medicine, Ross was also interested in poetry, and he actually wrote multiple poems about his war against malaria.
