The full name of AIDS, "Acquired Immune Deficiency Syndrome" (in English acronym AIDS), is due to infection with HIV or human immunodeficiency virus (abbreviation HIV) as a harm caused by large, high fatality rate of serious infectious diseases. HIV attacks the body's immune system, making the body resistance decreased gradually until the loss will eventually lead to death. There is no effective vaccine and cure of the drugs, but the disease is completely preventable.
HIV-wide known as the human immunodeficiency virus, is the pathogen that causes AIDS. HIV exists in the person's body fluids, in blood, lymph, semen and vaginal secretions in the concentration, milk and saliva also contain HIV. Anti-HIV antibodies in the blood there is no protection. HIV resistance to the external environment is very low. HIV is sensitive to heat, boil quickly inactivated, liquid (even with 10% serum) in HIV-heating 56 ℃ 10 minutes inactivated. At 37 ℃, with 70% alcohol, 10% of the bleaching powder, 296 glutaraldehyde, 4% formalin, 35% isopropanol, 0.5% Lysol or O.3% hydrogen peroxide and other disinfectants for 10 minutes. Can inactivate HIV.
How to know if infected with the AIDS virus
To check the blood to determine HIV antibody. Usually 4 weeks after infection can detect HIV antibodies, very few of the needs of 3 months.
Therefore, high-risk behavior should be 4 weeks after the screening test. Screening negative, you need to 3 months after the review.
Who risk of HIV infection
1. Male homosexuals, including dual-sex persons (referring to both heterosexuals and homosexuals have
2. Intravenous drug users
3. Require frequent importation of foreign-derived clotting factors in patients with hemophilia
4. To accept blood transfusion and blood products were
5. With the high-risk groups who engaged in sexual relations
What is the source of infection of AIDS
HIV-infected persons and patients present in the blood, semen, vaginal secretions, breast milk and wound exudate, so HIV-infected persons and patients are a source of infection. Especially those in the incubation period of HIV infection have no symptoms, is very dangerous source of infection.
What are the symptoms of AIDS got
Common symptoms include:
1. Systemic symptoms: slight fever, weight loss, fatigue, chronic diarrhea, etc.;
2. Lymphadenopathy: common in the neck, submandibular or axillary lymph nodes;
3. Skin lesions: rash, genital warts and Kaposi's sarcoma, etc.;
4. Central nervous system symptoms: subacute encephalitis, dementia, etc..
What is the spread of AIDS
Main mode of transmission are:
1. Blood-borne type containing HIV transmission caused by blood and blood products; the use of strict sterile without surgery, injections and other invasive cosmetic body extraction equipment can be spread of AIDS; sharing of syringes by drug use is a significant risk of blood-borne AIDS行为.
2. Of sexually transmitted genital sexual activity is likely to result in subtle mucosal damage, the virus enters the body from the breakage.
3. Mother to child transmission of HIV infected women in pregnancy, childbirth or breast-feeding may transmit the virus to the fetus or infant.
How long after infection, the incidence
From human HIV infection to onset of clinical symptoms without obvious symptoms between the period of time, called the incubation period. The shorter incubation period of less than 1 year, elderly people can reach more than 15 years, an average of over 7 to 10 years will develop into AIDS patients. The duration of the incubation period of HIV transmission related to incubation period of infection through blood transfusion is very short.
Where can I get HIV counseling and testing
With high-risk behaviors (such as dirty sex, intravenous drug use or blood-selling history) who can be made to municipalities across the province and some of the county Center for Disease Control and Prevention and the health administrative departments at all levels of medical institutions designated to conduct counseling and testing. Test results will be kept confidential.
Which way to the spread of AIDS
Only carriers of germs, or his body an adequate amount of live virus, and have the appropriate transmission time, can cause infection, so infected with the AIDS virus and the patient in daily life and working-level contacts, such as shaking hands, hugging. Courtesy kissing, sharing of tableware, common meals, shared office equipment, tools, telephones, coins, shared toilets, bathrooms, swimming pool, cough. Sneezing, etc. will not be infected.
Mosquito bites can not transmit AIDS. Bites of mosquitoes infected with the AIDS virus, the number of mouth on the far from sufficient to infect it bites the next person, but would not have sucked the blood of stomach and then spit into the other person's body, the AIDS virus in the mosquito body can not survive.
How to prevent AIDS
1. Prevention of sexually transmitted
Mutual loyalty between husband and wife, sexual partner-specific. The proper use of quality standards for condoms. Not only contraception, but also significantly reduce the infection and the spread of AIDS, STD risk.
2. Prevention of blood-borne
To promote voluntary blood donation, less than government-approved blood collection point without the blood.
To avoid unnecessary injections and transfusions, if necessary, the use of tested and blood or blood products. Use of disposable syringes.
Do not abuse, not to share syringes with others drugs.
3. Prevention of mother to child transmission
HIV infection if a pregnant woman. Her fetus or infant is about 30% of the possibility of infection, so HIV-infected pregnant women is best not to, once pregnant, the best termination of pregnancy. To pregnant women taking antiviral drugs, cesarean section, artificial feeding, your baby can decrease infection rates.
HIV can live as healthy people do the same
HIV-infected persons can be as healthy people to participate in whatever work.
Infected person has the responsibility to protect others from being infected themselves. To live together with others when you should pay attention to: their own contaminants such as blood and body fluids should be disinfected to prevent others skin, eyes or mouth in direct contact; each sex life should be consistent use of condoms; husband and wife are subject to regular medical examinations.
