Zika: Aedes Aegypti Mosquitoes Love Biting Humans, And That’s Why They Spread Viruses So Well

id = " While researchers are working to develop a vaccine the Zika virus outbreak to combat the spread through South America, efforts to control spreading the virus are focusing on the mosquito Aedes aegypti .


This particular mosquito is especially good in the transmission of disease from one human to another. Zika addition, this is also a mosquito vector for dengue, yellow fever and chikungunya.
Aedes aegypti. Paulo Whitaker / Reuters have been studying Ae. aegypti - where he lives and how it behaves -. 15 years Aedes aegypti is adapted to live in close proximity with humans, and this close association probably contributes to gravity this outbreak. Aedes aegypti in a place near you? Aedes aegypti is an invasive species to the Americas. It originated in Africa, and is believed to have been brought back to the ships of the slave trade in the first 15 through 17 century. This mosquito is found in tropical and subtropical areas, including all central and much of South America. In the USA. you can easily find in the southeast and some small pockets in the Southwest, but not in areas that experience cold or very low temperatures and the most pronounced changes in daylight. Aedes aegypti is a biter during the day, which means it is active when their preferred food choice - humans -. They are away from home Aedes aegypti just loves people There are many species of mosquitoes, but not all of them spread disease in people. Some prefer to feed on other mammals or birds. Ae. aegypti , however, she prefers to feed on humans. In fact, Aedes aegypti prefers human blood on other animals, which increases their ability to transmit the virus from person to person. All mosquitoes are attracted to carbon dioxide in the breath because in them clues a, breathing living source of blood . Aedes aegypti females also detect signals from the smell of our sweat . They are attracted by lactic acid and ammonia in our breathing and skin as well as fatty acids secreted by the sebaceous glands at the base of our hair follicles (which would be the things that makes it look oily hair and smell). Man Ae. aegypti feed on nectar and sugar, no blood, but can also detect these olfactory signals so they can find potential partners that are hanging around humans. While people generally smell good woman Ae. aegypti mosquitoes, some people smell particularly good. The microbiota - bacteria that live on your skin - are another factor in this field. Because we are all different host groups of bacteria, each has a "smell" different from the female mosquitoes, and that could be why some people smell more attractive than others. And all these factors vary with age. Because we get bigger with age, it increases the surface area of ​​the skin, so we can assume that the larger people (ie, adults) emit more of these attractive than smaller people (ie children) . Aedes aegypti lay their eggs in containers produced by man In addition to finding human blood tasty, feminine Ae. aegypti tend to lay their eggs in man-made containers such as buckets, glasses, tire debris or cemetery vases filled with water. Rain or watering daily irrigation systems makes containers bases including potted plants, birdbaths and pleasant for larval development homes sources. Other species of mosquitoes prefer natural sources of water to lay their eggs, such as small ponds or near streambeds flooded. Species preferring these habitats will not have the same proximity to humans as the species that likes to lay eggs in our backyards, like Ae. aegypti . Due to the proximity of water sources for humans affect the chances of being bitten by an infected potentially mosquito several researchers have begun to classify which water containers are more attractive to women Ae. aegypti . In a large study in Iquitos, Peru, where dengue is common, the researchers found several factors that make a site more attractive to women

• If larvae are already present in a container, the woman knows she has all the requirements necessary for their future offspring. It's kind of like choosing a restaurant in an unfamiliar city :. If it is full, then you know it is good
• A careless container is more attractive than a managed container because it can accumulate more nutrients from decaying leaves or other organic matter. The more nutrients, bigger than the larvae grow.
• A container that receives more sunlight is more attractive because it is warmer and mosquitoes need warm temperatures to develop.
• Finally, size matters. Of those man-made containers that are close to human activity, larger containers tend to have more developing larvae of smaller containers. However, although the size is important, we can still find larvae in small containers such as cans of coke.

educate the community about the emptying of unnecessary containers and covering deposits larger water are an important part of the control effort and know what makes an attractive package can help people are directed to specific containers. In areas where diseases Ae transmitted. aegypti are present, this becomes extremely important. arm ourselves with more knowledge Knowing that Ae. aegypti prefer humans, we can protect ourselves by using long-sleeved shirts and long pants, and use mosquito repellents containing DEET or other repellents approved by the CDC . In cleaning the areas around our houses of containers that can collect water or emptied periodically ensure that our containers, we can reduce the population and therefore reduce the frequency with which has been chopped. The fact of having been bitten by a mosquito does not mean that you have been bitten by one who is carrying a disease. Even if you are bitten by a Ae. aegypti mosquitoes does not necessarily mean that you have been exposed to Zika, or any other virus. Not all Ae. aegypti are infected and not all mosquitoes are Ae. aegypti .
