would it spread if the aedes mosqoito was not there? why or why not?
Answers
Explanation:
The dengue virus is spread through a human-to-mosquito-to-human cycle of transmission, with the mosquito Aedes aegypti as the primary vector. These mosquitoes live near humans in tropical and subtropical regions of the world. Female Aedes aegypti become dengue vectors after feeding on the blood of a person infected with the dengue virus. Infected mosquitoes continue to transmit dengue with each blood meal for the rest of their lives. Aedes aegypti have a complex life cycle that includes aquatic and terrestrial stages. These mosquitoes lay their eggs inside containers, and new Aedes aegypti hatch when the containers are filled with water. Dengue poses the greatest risk in highly populated regions with rainy seasons where there are large populations of Aedes aegypti with a high degree of contact between the mosquitoes and humans.

Dengue is spread through the bite of the female mosquito (Aedes aegypti). The mosquito becomes infected when it takes the blood of a person infected with the virus. After about one week, the mosquito can then transmit the virus while biting a healthy person. The mosquito can fly up to 400 meters looking for water-filled containers to lay their eggs but usually remains close to the human habitation.
Aedes aegypti is a daytime feeder: The peak biting periods are early in the morning and in the evening before dusk.
Dengue cannot be spread directly from person to person. However, a person infected and suffering from dengue fever can infect other mosquitoes. Humans are known to carry the infection from one country to another or from one area to another during the stage when the virus circulates and reproduces in the blood system.
Aedes aegypti has evolved into an intermittent biter and prefers to bite more than one person during the feeding period. This mechanism has made Aedes aegypti a very highly efficient epidemic vector mosquito.
