Explanation:

Malaria can be caused by five different species of Plasmodium.

PORTAL OF ENTRY AND MODE OF TRANSMISSION: Malaria is always transmitted by the bite of a female Anopheles mosquito infected by plasmodium. Transfusion of blood from one infected person to another and use of contaminated needles and syringes are other potential modes of transmission. Congenital transmission of malaria can also occur. When the parasite enters the blood via the saliva of the mosquito it multiplies in the blood and enters the liver and infects the person who present symptoms of malaria as chills fever headcahe joint pain. Humans are the reservoir for the plasmodium species causing malaria.
