Humanity began to kiss to spread viruses and to immunize

By kissing it will cause tooth decay from mother etc. to babyMutans fungusAlthough it may be relatively known that it will be handed over, it is not only bad things to convey bacteria and viruses through drowning.

There are usually no problems in the substances handed over via saliva, but when infected during pregnancy it also contains very dangerous viruses and by contact with men through kissing, She seems to be able to gain immunity against this virus before she gets pregnant.

Details are as below.Kissing was developed 'to spread germs' - Telegraph

Cytomegalovirus(Scientific name human herpesvirus 5) This virusHerpes virusIt is a kind of sediment which exists widely in sap and it does not require treatment, especially if a healthy person is infected, but if women are infected for the first time in the early pregnancy, they will be transferred to the fetus and cause miscarriages and birth defects.

Medical HypothesesIn a paper published in a magazineUniversity of LeedsDr. Colin Hendrie said, "In order for a woman to receive a vaccinated vaccine of a particular male cytomegalovirus, exchanging the fluid by touching the mouse-to-mouse, in particular the flow of the liquid, It is the most effective in the case of a direction to a woman who has a low height. "

Especially the most prevention is to continue kissing with the same person for 6 months. As the relationship becomes more intimate and the kiss gradually becomes passionate, the immunity of women increases and the risk of causing severe symptoms due to infection is low. And when a woman is pregnant, the risk of infection of the fetus is even lower.

Scientists have thought that kiss has played the role of evolutionary quality control. It is the theory that we have judged elements of reproductive ability, health, genes etc. of the opponent of the kiss with the solution.

But with Leeds UniversityUniversity of Central Lancashire(Central Lancashire University)Psychologists say that these elements can be judged even if they do not get intimate enough to kiss. "Information on body shape, smell, reproductive condition, the presence or absence of diseases and hygiene of the body and oral cavity (etc) can only be obtained by approaching the closest distance (without exchanging dross)", Dr. Hendrie I am talking. "A small supplementary information obtained by kissing (to assess opponents of breeding) will not be enough to push the development of the act of kissing backwards."

It is said that gradually becoming intimate with the same partner and forming immunity to the virus leads to a safe birth, so it is better to make a child slowly through a romantic period biologically rather than making a child at the encounter It is recommended that it is recommended.
