What is the phenomenon of venereal disease?

"strange" phenomenon of venereal diseases

There are six "strange" phenomena in venereal diseases that we cannot explain at present:

Strange: there is almost no innate immunity to sexually transmitted diseases to prevent infection.

Skin and mucous membrane is the body's natural disease defense barrier, even if people come into contact with countless harmful microorganisms every day, they are rarely infected, and even if they break the skin, they will recover naturally in three or five days. Most sexually transmitted diseases are infected through the genital mucosa, which has almost no resistance to STD pathogenic microorganisms. once infected, the incidence is inevitable.

The second strange: the STD pathogen has low resistance to the outside world.

Mycobacterium tuberculosis can survive in a dry environment and maintain its infection ability for more than 3 months, so it can be transmitted through daily necessities; after the pus is dry, the staphylococci in it can survive for two or three months; and the infectious ability of salmonella in feces can be maintained for a month or two. STD pathogens die quickly after leaving the human body, thus greatly reducing the risk of indirect transmission. For example male masturbation toys , Treponema pallidum dies on its own in a dry environment after leaving the human body; Neisseria gonorrhoeae has autolysis, and after leaving the human body, the bacterial cells can dissolve themselves and "commit suicide", even if it is not autolyzed, it will lose infectivity in a short period of time; the frightening AIDS virus also quickly loses infectivity after leaving the human body.

Three strange things: STDs can endanger spouses and children

If one person between husband and wife has an STD, it will be passed back and forth between them like playing table tennis, and unless both parties are cured at the same time, the spread will go on endlessly. Infants and young children are accompanied by STD parents day and night, and daily necessities are difficult to isolate chastity cages , so infants and young children are likely to be infected. Some sexually transmitted diseases can be transmitted through the placenta during the fetal period, such as syphilis and AIDS. When the fetus is infected with Treponema pallidum, the face can show the characteristics of congenital syphilis at birth small vibrator , thus telling the world: "my relatives have syphilis." It really broke the child's heart.



Four strange things: there is no effective vaccine for venereal diseases.

Meningococci and Neisseria gonorrhoeae belong to Neisseria gonorrhoeae, many characteristics are very similar, but meningococcal vaccine has long been available penispumpe , and despite efforts, gonococcal vaccine can not be used in practice. The application of smallpox vaccine has made smallpox disappear all over the world. Measles vaccine, polio vaccine, typhoid vaccine, cholera vaccine and so on all play an important role in the prevention of infectious diseases, but so far there is no effective vaccine to prevent venereal diseases.

Five strange things: unable to produce firm acquired immunity after suffering from venereal disease

Many infectious diseases can obtain post-disease immunity, some immunity can be maintained for life, re-exposure to this kind of microorganism will not occur again. And venereal disease otherwise, can be infected again come on again.

Six monsters: STDs cannot be transmitted by insects

No matter blood-borne STDs or mucosal STDs, they can not be transmitted by insects. There are many diseases transmitted by insects, such as malaria and Japanese encephalitis. Mosquitoes may infect people as long as they bite patients first and then healthy people. However, even blood-borne sexually transmitted diseases can not be transmitted by mosquitoes, and its mechanism has not been clarified.

The "six monsters" of sexually transmitted diseases suggest that people with high incidence of three types of sexually transmitted diseases should be decisive in preventing venereal diseases and should not take any chances, so that they will have an affair overnight and regret for life. In addition, some people rely on condoms to think that they can escape STDs, in fact, it is not foolproof, the most effective measure to prevent STDs is to be clean.
