Living conditions of HIV

Nowadays, many people will talk about the living conditions of HIV, especially those who have had direct or indirect unclean sex. Once they encounter any physical discomfort or bad mood, they will share the living state of HIV with AIDS patients.

Living conditions of HIV 1 HIV can only be parasitic in human blood, leaving the human body is easy to die, and its adaptability to the external environment is very poor. Very sensitive to temperature, 56℃ can kill you in 30 minutes, and the higher the temperature, the shorter the survival time; Many chemicals can kill it easily, and it can be completely killed by soaking it in 20% alcohol and 2.5% bleaching powder solution for 5 minutes.

Oil, salt, sauce, vinegar in the diet and gastric juice in the stomach can kill HIV; Good skin is the best barrier against HIV invasion; Except chimpanzees, other animals and insects will not be infected with HIV, so contact with poultry and livestock or being bitten by fleas, lice and mosquitoes in daily life will not be at risk of contracting AIDS.

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 five cases of AIDS 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.

People infected with HIV will develop into AIDS patients after several years, even as long as 10 years or longer, and will be infected many times because of the extreme decline of the body's resistance.

Such as herpes zoster, oral mold infection, tuberculosis, enteritis, pneumonia, encephalitis caused by special pathogenic microorganisms, candida, pneumocystis and other serious infections caused by various pathogens. Malignant tumors often occur in the late stage, consume for a long time and even die of systemic failure.

Living conditions of HIV 2 Living conditions and inactivation methods of HIV.

1, the living conditions of HIV

This is related to the environment and the HIV content in blood or body fluids leaving the human body, as follows:

1. 1, HIV can survive in liquid environment at room temperature 15 days.

1.2, items contaminated by HIV are contagious for at least 3 days.

1.3, blood with low HIV content will lose vitality after natural drying for 2 hours.

1.4, even if the blood with high HIV content is dried for 2 ~ 4 hours, once it is put into the culture medium, it can still enter and replicate when it meets lymphocytes.

2. Inactivation method of HIV virus

It is not difficult to see that isolated blood or body fluids containing HIV can cause infection. But HIV is also very fragile. The following is the inactivation of HIV:

2. 1, HIV in liquid can be inactivated when heated to 56℃ 10 minute, and can be inactivated quickly when boiled.

Treatment with disinfectants such as 70% alcohol, 10% bleaching powder, 2% glutaraldehyde, 4% fuming, 35% isopropanol, 0.5% lysol and 0.3% hydrogen peroxide at 2.2℃ and 37℃ for 0/0 minute can inactivate HIV.

2.3. HIV can only survive in living cells in blood and body fluids, but not in air, water and food. Without these blood and body fluids, HIV will soon die.

3, AIDS prevention methods

3. 1, lead an honest and clean life, don't go to illegal blood stations to sell blood, don't set foot in pornographic places, and don't rush in and out of some entertainment places; In any case, we should maintain a strong awareness of AIDS prevention; Don't take any chances; Don't try taking drugs out of curiosity.

3.2. If you are sick, you should go to a regular clinic or hospital and pay attention to the safety of blood transfusion. Don't have injections, tooth extraction, acupuncture and surgery in medical units, especially in individual clinics. The disinfection of medical devices is unreliable. Don't use unsterilized instruments for ear piercing, tattooing and beauty treatment.

3.3. Don't share razors, toothbrushes, etc. Together with others, try to avoid contact with other people's body fluids and blood, and disinfect the items contaminated by others in time.

3.4. Pay attention to contact with AIDS patients: When taking blood and injecting AIDS patients, the syringe should be disposable, and the patient's blood, excrement and contaminated items should be completely burned. The patient's utensils and medical instruments should be used by special personnel, such as razors, toothbrushes, towels and teacups. Washing hands with soap after defecation can achieve the purpose of disinfection.

Treatment of AIDS

1, immunotherapy and immune reconstruction

The principle of treatment focuses on nourishing spleen and kidney, including benefiting qi, enriching blood and nourishing yin and yang. In addition, the gradual increase and utilization of biological agents can prevent the collapse of the immune system and the onset of AIDS.

2, Chinese medicine treatment

The principle is the combination of strengthening body resistance and eliminating pathogenic factors, focusing on strengthening body resistance, emphasizing people-oriented, overall adjustment, less toxic and side effects, and easy to take for a long time. The effect is slow, but the effect is lasting, which is the comprehensive effect of many mechanisms and is not easy to produce drug resistance. It can improve symptoms, cooperate with the treatment of opportunistic infections, and contribute to the rehabilitation of diseases.

3. Anti-infection treatment

Anti-infection therapy is aimed at various opportunistic infections. It is mainly used for symptomatic treatment of pneumocystis pneumonia, toxoplasmosis, fungal infection, mycobacterium tuberculosis and Kaposi's sarcoma. Its therapeutic drugs include antiviral drugs, antibacterial drugs, antifungal drugs and antigenic antibiotics.

4. Antiviral therapy

Anti-HIV drugs fall into two categories. The first category is reverse transcriptase inhibitors, including nucleoside reverse transcriptase inhibitors and non-nucleoside reverse transcriptase inhibitors. The second type is protease inhibitor, which prevents the precursor protein from cracking into cells and leads to the accumulation of uninfected virus particles.

HIV survival conditions 3 HIV is the English abbreviation of HIV, and its characteristics mainly include the following points:

1, which mainly attacks the human T lymphocyte system.

2. Once it invades the cells of the body, the virus will be integrated with the cells, which will be difficult to eliminate for life.

3. Viral genes are very different.

4. Blood, semen, vaginal discharge, saliva, urine, milk, cerebrospinal fluid and brain tissue fluid with neurological symptoms are widely present in infected people, among which the concentration of blood, semen and vaginal discharge is the highest.

5, the resistance to the external environment is weak, and the effective disinfection method for hepatitis B virus is also effective for HIV disinfection.

6. Infected people have a long incubation period and a high mortality rate.

7. The genome of HIV is more complex than any known virus gene.
