What is the working principle of AIDS prevention and control in China?

The principle of AIDS prevention and control work is mainly to control the source of infection, cut off the route of transmission and protect susceptible people. We should appeal to the masses to lead an honest and clean life and not have high-risk sex with AIDS patients. Actively carry out antiviral treatment in early detection to improve the quality of life.

Adhere to the policy of giving priority to prevention and combining prevention with treatment, establish a mechanism of government organization and leadership, departmental responsibilities and participation of the whole society, strengthen publicity and education, take measures such as behavioral intervention and care and assistance, and implement comprehensive prevention and treatment.

preventive measure

1, healthy sex life can prevent AIDS.

Sexual life is a way to spread AIDS, so healthy sexual life can prevent this infection and prevent AIDS. Generally speaking, good quality condoms can effectively cut off the exchange of body fluids and greatly reduce the possibility of HIV infection.

2. Understand the route of HIV infection.

General contact with AIDS patients, such as shaking hands, going to public toilets, using public telephones, swimming, showering, talking, eating together, etc. , will not be infected with HIV. Therefore, to prevent AIDS, we must know the infection route of AIDS.

3. Homosexuality is more susceptible to HIV infection.

There is a special way of sexual behavior between gay men, so it is easy to hurt and bleed. Therefore, if the semen of the other party containing the virus enters the body through the damaged part, it will cause infection. Therefore, homosexuals should take safety measures in their sexual life to avoid being infected with AIDS.

AIDS is a very harmful infectious disease, which is caused by HIV infection. HIV is a virus that can attack the human immune system. It takes CD4T lymphocytes, the most important cells in human immune system, as its main target, and destroys them in large quantities, making human body lose its immune function. Therefore, the human body is susceptible to various diseases, malignant tumors can occur, and the mortality rate is very high. The average incubation period of HIV in human body is 8 ~ 9 years. During the incubation period of HIV, you can live and work for many years without any symptoms. Studies show that AIDS originated in Africa and was brought to the United States by immigrants. On June 5th, 198 1, the US Centers for Disease Control and Prevention published a case report of 5 AIDS patients in Morbidity and Mortality Weekly, which is the first official record of AIDS in the world. In 1982, this disease is named "AIDS". Soon after, AIDS quickly spread to all continents. 1985, a foreigner who traveled to China fell ill and died soon after being admitted to Peking Union Medical College Hospital, and was later confirmed to have died of AIDS. This is the first case of AIDS in China. Most of them are young and middle-aged, and 80% of them are in 18 ~ 45, which is the age when sexual life is more active. After being infected with AIDS, they often suffer from some rare diseases, such as pneumocystis pneumonia, toxoplasmosis, atypical mycobacteria and fungal infections.

After HIV infection, there may be no clinical manifestations in the first few years to more than 10 years. Once AIDS occurs, patients may have various clinical manifestations. Generally, the initial symptoms are like the common cold and flu, including general weakness, loss of appetite, fever and so on. With the aggravation of the disease, the symptoms are getting worse, such as candida albicans infection in skin and mucosa, herpes simplex, herpes zoster, purple spots, blood blisters, ecchymosis, etc. In the future, it will gradually invade the internal organs, and there will be persistent fever for unknown reasons, which can last for 3 ~ 4 months; Cough, shortness of breath, dyspnea, persistent diarrhea, bloody stool, hepatosplenomegaly and malignant tumor may also occur. Clinical symptoms are complex and changeable, but not every patient has the above symptoms. Dyspnea, chest pain, cough, etc. Often occurs when the lung is invaded; Invasion of gastrointestinal tract can cause persistent diarrhea, abdominal pain, emaciation and weakness. It can also invade the nervous system and cardiovascular system.
