This video explains the life cycle of the parasite responsible for malaria. Malaria is an infectious disease, affecting more than 200 million people worldwide. It is caused by parasitic protozoans belonging to the Plasmodium type. Malaria causes symptoms that include fever, vomiting, headaches and may lead to death. The diagnostic is not always easy as the disease can be asymptomatic for some time. However, there is hope that this will improve as scientists have developed better ways to detect malaria, including the diagnostic of malaria based on the smell of a person.
