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: -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: -The most common vectors are insects that suck blood, such as mosquitoes and ticks. VBDs occur in both animals and humans.

Detailed explanation-4: -Arthropods form a major group of pathogen vectors with mosquitoes, flies, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives.
