Many infectious diseases such as measles, chickenpox, smallpox and poliomyelitis can be effectively prevented by vaccination, but so far there is no effective artificial immunization method for sexually transmitted diseases. Popularizing the knowledge of sexually transmitted disease prevention and treatment in the whole society, making the public fully aware of the hazards that may be brought about by inappropriate sexual contact, and doing a good job in the tertiary prevention of sexually transmitted diseases are the main preventive countermeasures against sexually transmitted diseases. The primary prevention of STDs refers to the efforts of individuals and society to protect the healthy population from being infected by STD pathogens, with a view to reducing the incidence of STDs and improving health. Prevention of unclean sexual intercourse is the key to minimizing the chances of infection and reducing the incidence of STDs. In the control of STDs, quality education has special significance. CE Coop, Director of Public Health of the United States of America, in his report on AIDS to the American people, said, “Couples who share a monogamous relationship can avoid the transmission of AIDS through sex. If you and your partner have been faithful to each other for at least five years, neither of you is at risk. If one of you is not faithful, both of you are at risk.” At present, residents in western countries are very afraid and uneasy about the spread of AIDS, and they are even afraid and wary when they go out on the street to ride in a car, go into a bathroom, go to a restaurant, embrace and shake hands, which brings a great threat to the social life and the psychology of the residents. On the other hand, there are still some people who are indifferent to sexually transmitted diseases, their sex life is licentious, and even prostitution. This has become a serious social problem. Secondary prevention of sexually transmitted diseases refers to the early detection of sexually transmitted diseases in individuals and populations, and the rapid adoption of effective measures to achieve the purpose of controlling sexually transmitted diseases, shortening the course of the disease and reducing the prevalence rate. Early detection and thorough treatment of patients are the main links in preventing the spread of STDs. How to enable STD patients to receive treatment immediately after the onset of symptoms, and how to be examined as soon as possible after exposure to high-risk situations (i.e., after having had unclean intercourse or having had sexual contact with a high-risk group) are issues that must be taken into account in STD publicity and education work. STDs are mainly transmitted through sexual relations, but there are other or indirect factors, and it is not possible to generalize and emphasize the issue of sexual relations. Put STDs and human ideology, or STDs and sexual morality is too tightly linked, often resulting in some patients have ideological concerns, unwilling to find a doctor’s office, or not to the regular hospital. As seeking street corner doctor secretly treatment, resulting in misdiagnosis and misdiagnosis, treatment is not complete. To the patient brings heavy economic burden and psychological burden. Admittedly, the social attitude towards STD patients is an objective factor of whether STD patients can treat themselves correctly. Social discrimination against patients with STDs, the family’s blame, individual hospital doctors treat patients as “sinners” to interrogate, these can only produce negative effects on patients. In addition, the early detection and correct treatment of patients depends on the patient’s ability to consciously consult a doctor in a timely manner, but also depends on the ability to diagnose and treat sexually transmitted diseases. Popularize new technologies and methods of diagnosis and treatment of sexually transmitted diseases among the medical staff of specialized dermatological and venereal diseases departments, and improve the level of treatment in this area. In outpatient clinics of non-STD specialties such as obstetrics and gynecology, urology, etc., patients with STDs or suspected patients are found in a timely manner and referred to dermatology departments, and after the diagnosis is confirmed, the most effective medicines are reasonably used with the correct dosage and adequate full treatment, so as to make the patients cured as soon as possible and completely. Tertiary prevention of STDs is aimed at reducing injuries and disabilities caused by STDs, minimizing complications and improving patients’ ability to adapt to life. Adverse consequences of STDs, such as bone, cardiovascular and neurological damage caused by advanced syphilis; AIDS due to cellular immunodeficiency caused by conditional infections or selective malignant tumors, etc.; STDs caused by pelvic inflammatory disease, ectopic perinatal pregnancy, stillbirths and infertility and other serious complications; chronic extension of certain infections and recurrent episodes; vertical transmission and teratogenicity and other impact on the offspring; part of the viral The carcinogenic potential of sexually transmitted diseases caused by some viruses, etc., are all elements of the tertiary prevention of sexually transmitted diseases. In addition, some STDs can be transmitted through blood transfusion, shared syringes among intravenous drug addicts and close contact in life. Therefore, people with STDs cannot be blood donors. Similarly, recipients of blood must be cautious about receiving blood transfusions and avoid using foreign blood products. Abstinence from drugs and isolation of patients are also necessary to prevent STDs.
