Malaria is one of the major killers in Africa. Have the scientists discovered its new origin? Find out now.
New researches, which consider malaria questions, have been conducted recently. Initially people thought that this is a modern disease. But it has appeared not so. According to scientists, this infection could exist already more than 8 million years ago. They say even successors of dinosaurs probably had it too.
It is the illness, which is usually transmitted by mosquitoes. However, there are also hereditary types of this infection, but they can be met extremely seldom.
Now scientists think how animals could survive and develop after this disease.
As the illness breeds at insects, vertebrate animals don’t become its carriers. It is considered that Gregarinida is the first source of an illness. This is a parasite. It existed in protozoa and could infect insects, which extend the infection today.
Malaria death toll is quite high. According to World Health Organization, about 40% of the Earth population is exposed to risk of malaria.
Annually more than 500 million people get sick with illness in a severe form. The majority of cases of diseases and death occur in the countries of tropical Africa. Malaria in Nigeria is also widespread.
