Detailed explanation-1: -Malaria is a parasitic infection transmitted by Anopheline mosquitoes. It causes an estimated 219 million cases globally, and results in more than 400, 000 deaths every year. Most of the deaths occur in children under the age of 5 years. Dengue is the most prevalent viral infection transmitted by Aedes mosquitoes.

Detailed explanation-2: -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-3: -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-4: -Aedes aegypti mosquito. Dengue viruses are spread to people through the bites of infected Aedes species mosquitoes (Ae. aegypti or Ae. albopictus).
