According to statistics, there are about 3,000 species of mosquitoes in the world, of which only 80 species bite humans, mainly Anopheles, Aedes and Culex. Mosquitoes reproduce very quickly, a single mosquito can lay hundreds of eggs at a time, larvae can live in a variety of environments, from water to land.
The proliferation of mosquitoes has become a serious public health problem around the world. The biggest threat of mosquitoes is the transmission of diseases, with more than 80 diseases, common are malaria, yellow fever, dengue fever, Japanese encephalitis… According to statistics of the World Health Organization WHO, Every year around the world, about 700 million people suffer from various diseases caused by mosquitoes, of which one in 17 people dies.

The process of sucking blood of mosquitoes is as follows: After a mosquito lands on you, you will plug the nozzle into your skin, looking for blood vessels to suck. At the same time, mosquitoes will inject you with a vasodilator, which helps blood to flow out instead of clotting, while they “enjoy”. Meanwhile, the body’s immune system produces histamines, which cause the skin around the sting to itch. The histamine reaction sometimes doesn’t happen immediately, but a few hours after the mosquito’s saliva enters the body.
What objects do mosquitoes like to bite?
Sometimes we wonder, why is it that even in the same room, some people get bitten by mosquitoes and others don’t?
In fact, mosquitoes fly and look for objects to bite thanks to the carbon dioxide they “smell”. Mosquitoes can sniff out a target at a distance of about 50m. The stronger the signal the body sends to the mosquito, the greater the chance of being bitten. Therefore, the more carbon dioxide someone exhales or the more CO2 the body emits, the more likely you are to attract mosquitoes. The following people are susceptible to mosquito bites:
People who sweat a lot
Summer heat easily causes the body to sweat, easily causing a sour smell on the skin and clothes. Research shows that people who sweat a lot often have more lactic acid in their blood. When you sweat, the amount of lactic acid released through your skin increases. Mosquitoes are especially attracted to this smell, so they will attack you.

An American study also showed that people who often drink alcohol, causing body temperature to rise, increase the amount of CO2 excreted through, are also prone to mosquito bites.
People with rapid breathing
People with a rapid breathing rate exhale more carbon dioxide. When mosquitoes detect an object – within a range of about 15m, they will immediately fly to you to bite you.
People in dark clothes
Mosquitoes like dark, so in the summer, they like objects that wear dark clothes. Therefore, in the midst of a crowd wearing light clothes, if you wear dark clothes, you are susceptible to mosquito attacks.
In addition, people with dark skin are often bitten by mosquitoes, while people with light skin are much less likely to be bitten.
People with a fast metabolism
People with a fast metabolism are more susceptible to mosquito bites, because a fast metabolism means a healthy body, active, and sweat a lot. Meanwhile, for the elderly and sick, the possibility of being bitten by mosquitoes will also be greatly reduced, because the metabolism in this group of people takes place relatively slowly.
obese people
Obese people often sweat more easily, breathe quickly, produce more CO2 than the average person, so they are susceptible to mosquito attack. This also happens to pregnant women – those with high body temperature, respiratory rate faster than other people.
People with blood type O
A Japanese study shows that mosquitoes like people with blood type O. This is also the most common blood type in the world, so it is understandable that many people get bitten by mosquitoes.
When bitten by a mosquito, the body is itchy and uncomfortable. (Illustration).
How to prevent mosquito bites?
Should clean the house and living environment, so that mosquitoes do not have a place to grow and breed.
Indoors, you can burn essential oils, use a mosquito repellent, plant mosquito repellant plants, and limit dark and dirty areas.
Wear light instead of dark at night. Should take a clean bath, limit exercise, avoid alcohol … will help mosquitoes not to visit you.
Going to bed should wear a mosquito net. Protect yourself by applying mosquito repellent and repellant creams on your body before going into areas where there may be a lot of mosquitoes.
