Why do some people particularly recruit mosquitoes? Recently, the "Cell" magazine discovered the mystery: there are two viruses infection that allows the human body to emit a special smell, attract mosquito blood -sucking, and spread the virus to the next person.

These two viruses are famous dengue fever and Zika virus.

Denging fever is high in tropical areas, occasionally appears in the subtropical region. More than 50 million people in the world are infected and 20,000 people die. Most of them are children. Infection can cause fetal birth defects.

The virus needs to be propagated with mosquitoes as the medium. Experts believe that malaria and certain inflammation can affect the smell of human body, and tropical viruses such as dengue fever and Zika may have similar attraction mechanisms.

First of all, the researchers let mosquitoes come into contact with dengue fever infection mice and ordinary mice, and found that mosquitoes like to infect mice. Further found that the phenylthone in the infected mouse smell is particularly attractive to mosquito. In the skin smell of human dengue fever, more phenylthone is also found.

Pepterone is the metabolites of Bacillus on the surface of the skin. The skin will produce a antibacterial peptide inhibit the number of bacteria, while mice will not produce a large amount of antibacterial peptide after dengue fever and Zika. Bacillus grows faster, metabolizes more phenylthone to attract mosquitoes. An interpersonal communication.

Researchers are treated with different -dimensional A acids for dengue rodent. This is a substance that can promote the secretion of skin antibacterial peptide. The release of phenylone release is reduced, the attractiveness of the infected mouse to mosquitoes is reduced, which also reduces the potential risk of virus infection. In the next step, scientists will verify the connection between skin odors and microorganisms under real world conditions, and try the effects of human application of different dimensions of A.

Dengue fever and Zika are relatively rare outside the tropical. Does other viruses also have the effect of attracting mosquitoes? Recruiting mosquitoes may not be because you metabolize and sweat a lot, it is likely that the microorganisms in the body are showing mosquitoes: Come on, come!
