Why do mosquitoes bite some people more than others?

In mosquitoes, it is only the female that bites. She doesn't do it to annoy us. No, she does it to bring proteins - those contained in the blood - to her eggs to help them develop. The problem is that mosquitoes are a source of infection in some parts of the world. So the researchers wondered what factors might guide their choice of one prey over another.

Mosquitoes prefer women

Mosquitoes first locate their prey through the carbon dioxide they exhale. Then, their choice is based on a number of other criteria, which can vary depending on the type of mosquito. Globally, mosquitoes would prefer women whose skin is thinner and easier to pierce.

More stings on sweet skins

A Japanese study has shown that people with blood type O tend to attract mosquitoes more than others. Since these little beasts like what is sweet, they will also go after people whose body chemistry tends to secrete more carbohydrates.

Finally, bacteria that are everywhere in the human body also have a role to play. Scientists - this time from the Netherlands - have discovered that mosquitoes are more attracted to people who harbor a large number of bacteria but few different types.

Everyone reacts differently to mosquito bites

It should be added that reactions to mosquito bites vary depending on the victim. Some experience unbearable itching. Others have no reaction at all and may, in fact, believe that they have not been bitten!
