Malaria

About:

• It took more than 30 years and approximately $700 million for this breakthrough.
• Malaria kills nearly 600,000 people every year, the majority of whom are children under the age of five in sub-Saharan Africa.
• Malaria is a disease caused by the Plasmodium parasite.
• The parasite can be spread to humans through the bites of infected mosquitoes.
• There are many different types of plasmodium parasite, but only 5 types cause malaria in humans.
  • Plasmodium falciparum – mainly found in Africa, it's the most common type of malaria parasite and is responsible for most malaria deaths worldwide.
  • Plasmodium vivax – mainly found in Asia and South America, this parasite causes milder symptoms than Plasmodium falciparum, but it can stay in the liver for up to 3 years, which can result in relapses.
  • Plasmodium ovale – fairly uncommon and usually found in West Africa, it can remain in your liver for several years without producing symptoms.
  • Plasmodium malariae – this is quite rare and usually only found in Africa.
  • Plasmodium knowlesi – this is very rare and found in parts of Southeast Asia.
• Transmission:
  • The plasmodium parasite is spread by female Anopheles mosquitoes, which are known as "night-biting" mosquitoes because they most commonly bite between dusk and dawn.
