What disease is AIDS? How did AIDS come from?

AIDS is a human virus and a very serious infectious disease. If an AIDS patient, even a slight cold can kill you, what is AIDS? Let's take a look together.

What disease is AIDS?

AIDS is a serious infectious disease, which is caused by HIV (human immunodeficiency virus for short) invading human body, destroying human immune function, causing various incurable infections and tumors, and finally leading to the death of the infected person. AIDS is the acronym of the full name of AIDS medicine, acquired immunodeficiency syndrome. This name expresses the complete concept of AIDS, from which we can learn three clear definitions of AIDS: acquired: in etiology, it refers to acquired rather than congenital.

Immunodeficiency: refers to the pathogenesis, which mainly damages the human immune system, leading to the reduction and loss of the protective function of the immune system.

The common characteristics of immunodeficiency diseases are: a. the susceptibility to infection is obviously increased; B. it is prone to malignant tumors; C. the clinical and pathological manifestations are diverse.

Syndrome: refers to a complex symptom group caused by opportunistic infections of various systems and tumors caused by immune deficiency in clinical symptoms.

Aids is a disease of human immune defense system caused by retrovirus. When the human body is in a normal state, the immune system in the body plays a good "defense" role against the attacks of various pathogens. Once infected with HIV, this good defense system of human body will be destroyed, and the defense function will decline, so pathogens and microorganisms can take the opportunity to directly take blood and broken wounds. In addition, some abnormal cells in the body, such as cancer cells, also take the opportunity to grow rapidly, multiply and develop into various cancers. In other words, AIDS patients are mainly characterized by severe damage to the immune system, decreased physical resistance, and even induced serious infections and some rare cancers.

Where is the source of AIDS?

AIDS originated in Africa, and it was also 1979 that spread among Haitian youth and was brought to the United States by immigrants. On June 5th, 198 1, the centers for disease control in Atlanta, USA briefly introduced the medical history of five AIDS patients they found in Morbidity and Mortality Weekly for the first time. 1982, the disease was officially named "AIDS". Soon after, AIDS quickly spread to all continents. 1In June 1985, a young Argentine male tourist from Shanghai was hospitalized for AIDS and died in China, which was the first AIDS patient in China. From 65438, when AIDS entered China, to 0985, nearly 10,000 people were HIV carriers. According to the speculation of relevant departments, the development trend of AIDS in the next few years is: the developed countries show a downward trend, while the developing countries show a sharp upward trend.

AIDS is called "contemporary plague" and "super cancer", which has attracted great attention from the World Health Organization (WHO) and other countries. No matter the investment in personnel and funds, it has been listed as a Class B legal infectious disease in China, and it is one of the infectious diseases monitored by frontier health.

How to prevent AIDS

At present, there is no effective vaccine to prevent AIDS, so the most important thing is to take preventive measures. The method is as follows:

1. Adhere to integrity, do not engage in prostitution, and avoid premarital and extramarital sex.

2. Do not take drugs and do not share syringes with others.

Do not transfuse blood and use blood products without authorization, but use them under the guidance of a doctor.

4. Don't borrow or * * use personal items such as toothbrushes, razors and razors.

Using condoms is one of the most effective measures to prevent sexually transmitted diseases and AIDS in sexual life.

6. Avoid direct contact with blood, * *, milk and urine of AIDS patients, and cut off its transmission route.

How to treat AIDS

At present, there is still a lack of effective drugs to cure HIV infection worldwide. The current treatment goals are: to reduce the viral load to the maximum extent and for a long time; Obtain immune function reconstruction and maintain immune function; Improve the quality of life; Reduce HIV-related morbidity and mortality. The treatment of this disease emphasizes comprehensive treatment, including general treatment, antiviral treatment, treatment to restore or improve immune function, opportunistic infection and malignant tumor.

1. General therapy

HIV-infected people or patients with acquired immunodeficiency syndrome do not need isolation treatment. For asymptomatic HIV-infected people, they can still maintain normal work and life. Antiviral treatment should be carried out according to the specific condition, and the changes of the condition should be closely monitored. For patients with pre-AIDS or who have developed into AIDS, they should pay attention to rest according to their illness and give them a high-calorie and multi-vitamin diet. What can't be eaten should be supplemented by intravenous infusion. Strengthen supportive treatment, including blood transfusion and nutritional support treatment, and maintain the balance of water and electrolyte.

2. Antiviral therapy

Antiviral treatment is the key to AIDS treatment. With the application of highly effective antiretroviral therapy, the anti-HIV efficacy has been greatly improved, and the quality of life and prognosis of patients have been significantly improved.
