HIV screening laboratories have reached 49000, and designated anti viral treatment institutions have increased to more than 6000... In recent years, China's AIDS prevention and control service system has become increasingly perfect, and AIDS prevention and control has achieved remarkable results. December 1, 2022 is the 35th "World AIDS Day". This year, the theme of China's promotional activities is "Fighting AIDS Together and Sharing Health". Experts believe that the prevention and control of AIDS needs the attention and action of the whole society. Everyone should improve their self-protection awareness and skills and be the first responsible person for their own health. AIDS is harmful and has a high mortality rate. AIDS is a progressive immune function defect characterized by the reduction of CD4+T lymphocytes caused by human immunodeficiency virus (HIV) infection. In the later stage of the disease, it can be followed by a variety of opportunistic infections, malignant tumors and central nervous system diseases. AIDS is harmful and has a high mortality rate. According to the report released by the United Nations AIDS Programme, in 2021, 650000 people worldwide will lose their lives due to AIDS, and 1.5 million people will be newly infected with AIDS virus. According to the national epidemic situation of notifiable infectious diseases in 2021 released by the National Health Commission, the number of reported deaths of AIDS in China ranks first among the three categories of notifiable infectious diseases A, B and C. Li Taisheng, director of the Department of Infection of Peking Union Medical College Hospital, said that AIDS has three transmission routes: blood transmission, sexual transmission and mother to child transmission. People are generally susceptible to AIDS, which can be transmitted by contacting the blood, semen, vaginal secretion and milk with the virus. However, so far, there is no drug that can cure AIDS, and there is also a lack of effective vaccine to prevent AIDS infection. Once you are infected with AIDS, you need to take medicine regularly throughout your life. There is not much time left to achieve the UN goal of "ending the AIDS epidemic by 2030". Experts believe that in order to eliminate the harm of AIDS, individuals should first attach importance to and learn to master the knowledge related to AIDS prevention, refuse unsafe sex, stay away from drugs, improve self-protection awareness and skills, and do a good job in health protection. The prevention and control of AIDS needs to pay attention to early intervention. "Research shows that AIDS virus infected people caused by gay men's sexual behavior in China have an average of 4.8 years after infection, which suggests that more attention should be paid to relevant detection and early treatment." Li Taisheng said. Expanding testing is an important strategy for AIDS prevention and control. At present, China has formed a comprehensive testing service model, AIDS voluntary counseling and testing is one of them. According to the AIDS Voluntary Counseling and Testing Guidelines revised and issued by the China Center for Disease Control and Prevention, AIDS voluntary counseling and testing can be done in CDC at all levels, as well as some comprehensive medical institutions, maternal and child health care institutions, community health service centers, and township health centers. After AIDS exposure, it can be prevented and remedied. Lu Hongyan, director and chief physician of the AIDS Prevention and Control Institute of the Beijing Center for Disease Control and Prevention, said that after unsafe sex and other high-risk behaviors prone to AIDS, you should go to the hospital for consultation and testing in a timely manner, and use post exposure prophylactic drugs under the guidance of doctors. Preventive medication after exposure can effectively reduce the risk of AIDS virus infection. "In case of high risk
