Mosquitoes are considered one of the most dangerous creatures on the earth because of their ability to spread deadly diseases. The U.S. CDC report that the insects kill more than one million people per year just through the transmission of malaria. Add to that the numbers of those sickened and killed by other mosquito-borne diseases such as dengue fever, yellow fever and West Nile virus, and it’s easy to see how they earned their dangerous reputation. In recent years the rate of infection has risen dramatically, and a growing number of scientists are now concerned that global warming will translate into an explosive growth of mosquito-borne diseases worldwide. These are some of the most prevalent diseases spread around the world by mosquito bites:
West Nile virus
A viral infection carried in the blood of birds. Culex mosquitoes pick it by feeding on infected birds, then, after it spreads through their systems, pass it to humans through their saliva during feeding. The West Nile virus multiplies in the human blood stream and is carried to the brain, where it begins to affect the central nervous system and causes inflammation of brain tissue, known as encephalitis. If this happens, a person will develop high fever, headaches, swollen lymph nodes and stiff neck.In the most severe cases, the infection can lead to convulsions, coma and death. Even if a severely infected person survives, there is a good chance of permanent neurological damage. There is no specific treatment of West Nile virus.
The Zika virus is typically transmitted by the Aedes aegypti mosquito, but it can also be spread sexually, causing the CDC to update its guidance to couples. Aedes aegypti mosquitoes are aggressive daytime biters and officials are warning people of the need to be vigilant, cover up and reapply repellent regularly. The Asian tiger mosquito (Aedes albopictus) which is also established throughout the United States, and transmits dengue fever and Chikungunya, may also be capable of transmitting the Zika virus. There is no vaccine, treatment or cure for the disease and travelers to infected areas are being urged to prevent mosquito bites as the best and only protection against the disease. Pregnant women are being warned against travel to countries where Zika is present because of risk to their unborn babies.
Caused by parasites, primarily Plasmodium falciparum or Plasmodium vivax. Female Anopheles mosquitoes pick up the parasites by feeding on infected humans. The parasites develop in a mosquito’s body for 10 to 18 days, then is passed on when the mosquito injects saliva while feeding.Once in the human body, malaria parasites migrate to the liver, where they grow and multiply. Eventually the parasites move into the blood stream to continue developing in red blood cells. As they multiply and are released, they destroy the blood cells.
How to get rid of mosquito bites
Many professor of mosquito had suggest people using repellents sprays that mask the skin odors most attractive to mosquitoes make it possible for people to hide in plain sight. A repellent containing DEET or another proven chemical blinds the receptors mosquitoes use to pick up on skin odors, meaning they aren’t able to locate their prey. Apply it lightly to exposed skin, avoiding cuts and sores.but the problem is that it seems lots of people has got allergy of the spray and especially is not save for the baby, especially when they are sleeping. Nevertheless , the working period of that tradition proven chemical is shot that only about 4 hours for most product in the market. So, some clever consumer has found that there still have another choice like electric outdoor mosquito trap .But the traditional uv mosquito lamp just useless and they can just catch the insects which won’t suck human’s blood. Mosquito zappers on the other hand are thought to attract mosquitos by utilizing an ultraviolet light. However, the science behind how a mosquito finds its’ next meal couldn’t be further from an UV light. Mosquitos simply are not attracted to ultraviolet light as they are attracted to plumes of carbon dioxide. People are likely to find that the great company call QM had generate at new way to defend the mosquito’s bite.Contrary to the traditional mosquito zappers; QM’s outdoor mosquito trap work by emit the C02, and an environmentally friendly octenol scent attracts mosquitos the same way they are attracted to humans. As the insect reaches the trap the upward vacuum of the trap suck them in and dry them into the little box of the device. The working principle of IT04’s CO2 emit ability is base on the tech of TIO2’s nanometer coating. And with the ray of specific wavelength UV light on them, the any microorganism in contact with the coating surface will decomposition to CO2 and H2O and therefore, releasing a smell that attracts female mosquitoes. It’s sure that the QM’s Outdoor mosquito trap (Model IT04) is the most effective way to kill the mosquito in the market.(Reaching by Bio and mosquito specialist Doctor tetyl ,JC)
