People may catch HIV though oral sex with infected partner

Researchers have determined how people can catch HIV that causes
AIDS though oral sex with infected partners. As it turned out, there
may be no injuries inside of the mouth but a partner may still catch
the virus while having oral sex. After twenty five years of an
extensive research American doctors have determined that humans have
a molecule that comes in contact with the virus.

Up to now many doctors doubted that their HIV-infected patients were
honest when said that they had no unsafe sexual contacts. Doctors
believed that their infected patients, and especially men, would not
confess that they had oral sex with other infected partners. El Pais
reports that researchers have discovered a special molecule in the
tonsil cells, and the discovery has dispelled doctors' bias as
concerning the problem.

It was traditionally believed that only people with seriously
injured gums could catch HIV when having oral sex with infected
partners. However, the fact was not quite agreeable for all
especially when it was determined that human saliva has a strong
antiviral action. People will not catch HIV if use the same glasses
or forks that infected people have previously used, or even if they
kiss infected partners. People and many animals instinctively lick
their wounds to have primary disinfection thanks to the antiviral
action of their saliva.

The recent discovery gives a reasonable explanation of HIV
transmission. Researchers from the US National Institute of Health
say that tonsils have the CXCR4 receptor on their surface that helps
the virus contact infected cells and communicates its genetic
material to a human organism.

The molecule has been among the first molecules tested in a new
therapy for treating the infection. The gum surface is covered with
different type molecules called keratins that perform a barrier
function and make gum walls thicker. The results of the research
were published in American Journal of Pathology.

The discovery has become another opportunity for experts to
emphasize that people must use condoms not only for vaginal or anal
sex contacts but also for oral sex.
