The transmission of AIDS.
What is the transmission path of AIDS? There are three main ways of HIV transmission, including sexual transmission, blood transmission and mother-to-child transmission, among which the main transmission route of AIDS is through sexual transmission and blood transmission. The transmission path of AIDS does not include general contact, so AIDS patients should not be discriminated in their lives, such as sharing meals, shaking hands, etc., they do not infect AIDS.
The transmission of AIDS.
HIV transmission route 1: sexual contact transmission.
Including sexual contact with the opposite sex. Anal sex and oral sex have a greater risk of infection.
Transmission of AIDS 2: blood transmission.
(1) transfusion of blood or blood products contaminated with HIV.
(2) intravenous drug addicts share HIV contaminated, unsterilized needles and syringes.
(3) sharing of other medical devices or household utensils (such as sharing a toothbrush or razor with an infected person) may also be transmitted through the breaking point, but rarely.
(4) the syringe and needle sterilization are not complete or disinfected, especially if the child is not able to get one needle and one needle; Oral cavity instrument, delivery instrument, surgical instrument, acupuncture treatment with needle sterilization or disinfection; Haircuts, hairdressing (such as eyebrow, pierced ears), tattoo and other knives, needles, bathroom repair knives not sterilized; Sharing a shaving knife, razor, or sharing toothbrush with others; Transfusion of blood or blood products from donors without HIV antibodies, as well as bone marrow and organ removal in similar cases; When the wounded are bleeding, the victim’s own damaged skin touches the wounded blood.
HIV transmission route 3: mother-to-child transmission.
Also known as perinatal transmission, the mother infected with HIV transmitted HIV to the fetus or baby shortly before, during and shortly after delivery. It can be passed through the placenta or through the birth canal, or through breastfeeding.
HIV infection rate.
Unsafe sex is the most dangerous high-risk behavior for HIV, including heterosexual and homosexual ACTS. There is a certain chance that HIV infection will be transmitted. Depending on the sexual behavior, the risk of infection is different.
1. The incidence of HIV infection among female males: 1/700-1/3000 for females.
2. The incidence of HIV infection among male women: 1/200-1/2000 for males.
3. Male transmission men’s risk of HIV infection: the risk probability of male transmission is 1/10 to 1/1600.
Although many people do not see the high risk of HIV/AIDS from the data, many other factors in real life increase the risk of HIV infection. For example, people with early AIDS and those with advanced AIDS have the highest infectiousness, and the chance of infection is 1/10-1/20, because the virus content is highest in the infected person. The second infectious peak is the asymptomatic phase of the impending end of the clinical period, the chance of infection is 1/100-1/200, and the risk of asymptomatic infection is 1/1000.
Does saliva infect AIDS?
Does saliva spread AIDS? HIV can be found in saliva, but the amount of virus in it is very small, so it is almost impossible to transmit AIDS through saliva. A certain amount of HIV can be transmitted. It has been estimated that if the virus in saliva is to reach the level of infection, it is likely to swallow the saliva of an infected person more than 20 ml at a time. Saliva from American scientists have found that other people have a kind of “secretory leukocyte inhibit protease protein, the protein in the test tube can effectively inhibit HIV infection the body’s immune cells, so the general kissing, sharing meals, cough or sneeze is impossible to HIV infection. There are no reported cases of saliva infection in the current report.
Does kissing spread AIDS?
Does kissing spread AIDS? In general, kissing does not spread AIDS. HIV is found in the blood, semen, vaginal secretions, tears, urine, milk, and cerebrospinal fluid, which is very small in saliva, and does not cause the human body to become infected with the virus. Someone is calculated, under normal circumstances (no massive hemorrhage in the mouth), only by saliva contains some HIV, if you want to achieve the effect of HIV infection, need two gallons (7.5 liters) of saliva into each other’s body. And so far, the scientific community has not found a single case of kissing.
But it is important to note that HIV viral load in saliva, refers to a person without oral health problems, if have gum disease cause bleeding gums or mouth ulcers, then kiss spread HIV risk degree will have varying degrees of increase.
Does wearing condoms spread AIDS?
Does wearing a condom infect AIDS? Generally speaking, the probability of HIV transmission with a condom is very small. Condoms can provide a physical barrier, not only to achieve the purpose of contraception, but also to avoid direct contact with sexual partners of body fluids or blood, can effectively reduce the risk of AIDS. However, incorrect use of condoms or do not adhere to the use of condoms can greatly reduce its preventive effect.
Procedures for proper use of condoms:
1. Check validity period and quality;
2. Avoid puncturing the condom when opening the package. Check whether the condom is intact or not before use.
3. Put the condom on before the genitals contact with each other;
4, use in the whole process of sexual behavior, after the end of sexual behavior will be careful to take off the condom, tie the socket, wrapped with toilet paper after throwing into the trash can, not littering;
5, a condom can only be used once, can not be reused;
6. It is not necessarily safe to use more than 2 condoms at the same time, because the friction between condoms can easily make the condom break.
