Malaria

Every year more then 1 million people die of malaria and 300 to 400 million people are infected. Malaria is cannot be transmitted from person to person through causal contact though. This can be done by wearing insect repellant, using bug nets, and destroying area where mosquito's can live. Toxins released when the red cells burst are what cause the typical flu-like malaria symptoms.

Malaria can be prevented by reducing your exposure to mosquito bites.

Malaria usually is found in the hotter regions of the world. Africa, Southeast Asia, the Middle East, and Oceania are considered high risk malaria areas. Soon, the parasites leave the liver cells and enter red blood cells.

Since the malaria parasite is found in red blood cells it can also be transmitted through blood transfusion or use of contaminated needles. Once in the cells, they continue to grow and multiply. Parasites need the warmth to grow inside the mosquitos before they can to be transmitted to humans. You can also purchase antimalarial drugs if you are traveling to an area prone to malaria. However, there is no vaccine for malaria, and left untreated it can be fatal.
