How is malaria spread?
A
Enters body through food, water, or cuts in skin
B
Carried by animal vector
C
Airborne
D
None of the above
Explanation: 

Detailed explanation-1: -Malaria is transmitted to humans by female mosquitoes of the genus Anopheles . Female mosquitoes take blood meals for egg production, and these blood meals are the link between the human and the mosquito hosts in the parasite life cycle.

Detailed explanation-2: -Vector Biology Malaria parasites are transmitted to human hosts by female mosquitoes of the genus Anopheles. A diverse group of Anopheles (30 to 40 species) serves as vectors of human disease.

Detailed explanation-3: -Only Anopheles mosquitoes can transmit malaria and they must have been infected through a previous blood meal taken from an infected person. When a mosquito bites an infected person, a small amount of blood is taken in which contains microscopic malaria parasites.

Detailed explanation-4: -There is no animal reservoir for malaria parasites; it is a purely human disease.

Detailed explanation-5: -Biological vectors, such as mosquitoes and ticks may carry pathogens that can multiply within their bodies and be delivered to new hosts, usually by biting. Mechanical vectors, such as flies can pick up infectious agents on the outside of their bodies and transmit them through physical contact.
