How is malaria spread?

How is malaria spread?

Anopheles mosquito
  • Malaria is caused by an infection of the red blood cells with a tiny parasite called a protozoa
  • It is a vector-borne disease, which means it is spread by another organism - the Anopheles mosquito
  • When it bites an infected person the mosquito sucks up blood containing the parasite, which is then passed on to its next victim
  • Latest estimates suggest there are about 250 million cases each year, resulting in more than one million deaths
