What is the probability of primary infection in high-risk sex? High-risk sexual behavior refers to sexual behavior that easily leads to HIV infection. Generally, it refers to how high the possibility of primary infection in high-risk sexual behavior is without taking protective measures.
How high is the probability of primary infection in high-risk sexual behavior 1 The probability of primary infection in high-risk sexual behavior can be estimated according to the corresponding data, but there are only estimated values at present, and there is no particularly accurate statistical data. On average, about 1000 people have high-risk sex once, and 1 person is infected. But if sex lasts for a long time, the probability of infection may increase. If there are skin and mucous membrane injuries and wounds in this process, the probability of being infected with AIDS will increase obviously after contacting the body fluids of AIDS patients. After this happens, you can check the AIDS antibody for a period of time to judge whether you are infected.
What is high-risk sex?
The so-called high-risk sexual behavior refers to sexual behavior without condoms with non-fixed sexual partners or multiple sexual partners. High-risk sex is prone to sexually transmitted diseases and AIDS. After the occurrence of high-risk sexual behavior, close observation should be made, and patients should go to regular medical institutions in time if they are uncomfortable. At the same time, inform sexual partners to avoid cross-infection.
What should I do after high-risk sex?
1, blocking
Consult the local designated treatment hospital within 72 hours, buy and take blocking drugs (take them within 72 hours), and keep taking them for 28 days. Blocking drugs should be taken for 28 days. Even if they are tested during taking drugs, please take them for three months before testing. Blocking drugs also has the risk of blocking failure. Please keep safe sex.
Step 2 check
Comprehensive screening should choose a hospital with high level and professional detection methods or a local CDC. Don't sneak into an informal small clinic for fear of meeting acquaintances. Waste money and delay your illness.
Step 3 deal with
Early detection, early treatment, adherence to antiviral drugs according to doctor's advice, good compliance, optimism, reasonable nutrition, proper exercise and avoidance of other diseases.
4. Tell your sexual partner honestly
After the diagnosis, be sure to tell the people who have had sexual contact with you after high-risk sex, on the one hand, in order to avoid infecting more people. On the other hand, it is also for early treatment. If sexual partners are infected with sexually transmitted diseases and don't know it, they can't receive treatment together, so there is the possibility of cross-infection.
What is the probability of high-risk sexual infection? High-risk sexual behavior refers to sexual behavior that is easy to cause HIV infection, and refers to sexual behavior that has not taken any protective measures, including unprotected sex and multiple sexual partners.
Formal method
According to the transmission route of HIV, the behavior that easily causes the spread of HIV is called high-risk behavior.
1. High-risk sexual behaviors through sexual channels include unprotected sex and multiple sexual partners.
2. The high-risk sexual behaviors through blood route are: intravenous drug use; Others use syringes or other instruments that can pierce the skin; Use untested blood or blood products.
3. The high-risk sexual behaviors transmitted from mother to child are: HIV-positive women are pregnant and give birth, and HIV-positive mothers are breastfeeding, which may cause children to be infected with HIV.
Other forms
Ways that can cause blood infection, such as: tattoos, haircuts, ear piercings, beauty salons, pedicures and other knives are not disinfected; Use razors, electric razors and toothbrushes with others; Bleeding caused by sports injuries and fights; When rescuing the wounded, the broken skin of the rescuer comes into contact with the blood of the wounded.
Symptoms appear in a few days at the earliest after high risk.
It will take at least two to four weeks. However, it is suggested that you can go to the hospital for a check-up in two weeks, which is more reassuring. After high-risk behavior, the time period of AIDS testing is divided into three periods: window period (two weeks to six weeks), and testing can exclude 97%; Six weeks to three months, the detection can exclude 99.99%; After three months (only a few people will be negative in the first two periods, but the probability of being positive during this period is quite small), the test can exclude 100%. So you need to continue to observe your situation for 3 months before you can rule out the possibility of contracting AIDS.
Hiv usually has a three-month window. If the test results are negative after three months of high risk, HIV infection can be ruled out.
In daily life, for the sake of life and health, IBM should try to have unclean sex. Contraceptive measures must be taken during sexual life, and the simplest thing is to avoid pregnancy.
HIV mainly exists in the blood, semen, vaginal secretions and milk of infected people and patients. ① Sexual behavior: unprotected sexual behavior with infected partners, including homosexual, heterosexual and bisexual contact. ② Intravenous drug use: It is a very important way to spread HIV by using unsterilized injection tools used by infected people with others. ③ Mother-to-child transmission: During pregnancy, childbirth and breastfeeding, mothers infected with HIV may spread to fetuses and babies. ④ Blood and blood products (including artificial fertilization, skin transplantation and organ transplantation). Shaking hands, hugging, courtesy kissing, eating and drinking together, using toilets and bathrooms, using offices, public transportation and entertainment facilities will not spread HIV.
What is the probability of high-risk sexual infection? According to the route of HIV transmission, behaviors that are easy to cause the spread of HIV are called high-risk behaviors, such as unsafe behaviors such as intravenous drug injection, prostitution, whoring, multiple sexual partners, transfusion of blood or blood products that have not been tested for HIV antibodies, use of needles that have not been strictly disinfected, and occupational exposure.
The really high-risk sexual behavior is sexual behavior without any protective measures. Correct use of condoms with guaranteed quality, full use, no shedding and damage, is not a high-risk behavior. Intravenous drug injection with others is a high-risk behavior. If you use disposable needles yourself, you won't be infected with HIV.
Generally speaking, high risk actually includes the following possibilities that exist or exist alone.
