The Lifecycle of Malaria. Human Host

The video The Lifecycle of Malaria. Human Host by Drew Berry shows us how infected with malaria mosquito can vey fast spread an infectin among people. When a malaria-carrying mosquito bites a human, it injects a saliva with malarian parasite in human body and parasite enter in blood stream. With blood parasites enter a liver cell where it multiply its DNA over and over; so, one infected liver cell can create thousands of new parasites. They now are intering to red blood cell (RBC). Inside of RBC parasites hide from body immynsystem and replicate more and more. Finally, infected cell becomes mature and it bursts, sending more parasites in blood stream. And cycle begins again with thousands of parasites now.
Human infected by malaria suffer from fever, coma, convulsions, loss of blood due to damage of RBC, and brain damage. This year 10 % of population all over the world were infected by this disease, most of them were pregnant woman and children under the age of 5. We will study this disease along with other infection diseases and their causes later this semester.
