What happens if you get bitten by an Aedes mosquito?
Dengue fever is transmitted to humans via the bite of an infective Aedes mosquito. A mosquito becomes infected after it takes a blood meal from a dengue-infected person. It becomes infective after an extrinsic incubation period of 8 to 12 days. The mosquito then remains infective for the rest of its lifespan.
Do all aedes mosquitoes carry dengue?
Foremost, you need to bust the dengue myth that every mosquito bite will cause dengue. Only the female Aedes aegypti mosquitoes can spread the dengue virus and in fact, these mosquitoes can transfer the infection only when they themselves are infected.
How can you tell the difference between Aedes and Culex larvae?
They have a longer siphon, which is lighter in colour. Their body also hairy compared to Aedes. Their wings do not have black and white bands. Moreover, Culex mosquito does not make a sound when flying.
What diseases do Aedes aegypti transmit?
They are the main type of mosquito that spread Zika, dengue, chikungunya, and other viruses. Because Ae. aegypti mosquitoes live near and prefer to feed on people, they are more likely to spread these viruses than other types of mosquitoes.
Where are Aedes aegypti found?
This mosquito originated in Africa, but is now found in tropical, subtropical and temperate regions throughout the world.
How can you tell the difference between Aedes mosquito and normal mosquito?
The two species look similar, with black and white stripes on their bodies and legs. However, we can differentiate them by their scale patterns. Aedes aegypti has two white bands on its thorax (back) in the shape of a lyre, whereas Aedes albopictus has one white central band.
Will I definitely get dengue if bitten by Aedes?
Foremost, you need to bust the dengue myth that every mosquito bite will cause dengue. Only the female Aedes aegypti mosquitoes can spread the dengue virus and in fact, these mosquitoes can transfer the infection only when they themselves are infected. So, no need to panic after each mosquito bite.
Can one bite cause dengue?
An infected mosquito can later transmit that virus to healthy people by biting them. Dengue cannot be spread directly from one person to another, and mosquitoes are necessary for transmission of the dengue virus.
How do you identify a Culex mosquito?

Where do Aedes aegypti larvae come from?
Larvae of the disease vector mosquito, Aedes aegypti (L.) readily develop in ammonia rich sewage in the British Virgin Islands.
How do aegypti larvae survive in septic-water?
Results suggest that the observed alterations in excretory physiology of larvae developing in septic-water is a consequence of the high ammonia levels and that A. aegypti larvae may rely on ammonia transporting proteins coupled to active transport to survive in septic-water.
Why is the mosquito Aedes aegypti important?
The mosquito Aedes aegypti (L.) is a medically and economically important species because it is the vector of the arboviruses that cause dengue, Zika, chikungunya and yellow fever 1, 2.
Can Aedes aegypti be prevented from breeding in septic tanks?
Therefore, Aedes aegypti display a remarkable tolerance to high ammonia and effective surveillance and intervention methods to prevent breeding in septic tanks has been recommended in order to achieve successful mosquito control and disease prevention programs 3, 11.
