Detailed explanation-1: -In the case of malaria, the vector is the anopheline mosquito and the disease-causing organism is the malaria parasite. Humans and anopheline mosquitoes are both considered to be the parasite’s hosts.
Detailed explanation-2: -Anopheles Mosquitoes. 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-3: -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.
Detailed explanation-4: -Mosquitoes are examples of vectors. Mosquitoes carry Plasmodium, a protozoan, and transmit it from an infected person to a healthy person. Plasmodium causes malaria in humans.
