Epidemiologist: Malaria passes into the human population when a mosquito carrying the malaria protozoa bites a human who has no immunity  The malaria parasite can remain for up to forty days in the blood of an infected person  The disease cannot be passed from person to person, unless a non-infected person is exposed to the blood of an infected person  Theoretically, malaria could be eradicated in any given area, if all the mosquitoes carrying malaria in that area are exterminated
If such a course of action is carried out at a worldwide level, then the global eradication of malaria is possible
Malaria is still endemic in many parts of the world, and many health workers believe that the global eradication of malaria is not possible.
