Cause of Dengue: Aedes Mosquito

Aedes aegypti, commonly known as the yellow fever mosquito, is a mosquito that can host the dengue fever, Chikungunya and yellow fever viruses (and other diseases as well). One group of researchers recently proposed that A. aegypti be renamed Stegomyia aegypti [1], but this proposal has yet to be widely accepted by the scientific community. The mosquito can be recognized by white markings, although other mosquitos may have only slightly different patterns.[citation needed] The mosquito is most frequently found in the tropics[2]; it has some presence in the southeastern United States (such as the lower half of Florida), but it seems to have been competitively displaced by the introduction of Aedes albopictus.

Lifecycle of Aedes Mosquito

---

Under optimal conditions, the egg of an Aedes mosquito can hatch into a larva in less than a day. The larva then takes about four days to develop in a pupa, from which an adult mosquito will emerge after two days. Three days after the mosquito has bitten a person and taken in blood, it will lay eggs, and the cycle begins again.

Fast facts about the mosquito

Only the female aedes mosquito bites as it needs the protein in blood to develop its eggs. The mosquito becomes infective approximately 7 days after it has bitten a person carrying the virus. This is the extrinsic incubation period, during which time the virus replicates in the mosquito and reaches the salivary glands. Peak biting is at dawn and dusk. The average lifespan of an Aedes mosquito in Nature is 2 weeks The mosquito can lay eggs about 3 times in its lifetime, and about 100 eggs are produced each time. The eggs can lie dormant in dry conditions for up to about 9 months, after which they can hatch if exposed to favourable conditions, i.e. water and food References: 1. Reinert, J. F., R. E.

What is Dengue?

What is Dengue?

Dengue Fever and Dengue Haemorrhagic Fever (a more severe form) are the most common mosquito-borne viral diseases in the world. Dengue Fever is an illness caused by infection with a virus transmitted by the Aedes mosquito. There are four types of this virus (serotypes 1 to 4) which can infect you. Dengue Fever is spread through the bite of the Aedes Mosquito

THERE IS NO DRUG FOR DENGUE.

To prevent dengue fever, you must prevent the breeding of its carrier, the Aedes mosquitoes. Aedes mosquitoes are identified by the black and white stripes on their body. You can get rid of the Aedes mosquito by frequently checking and removing stagnant water in your home.
