AIDS transmission route and transmission conditions

In recent years, the number of AIDS patients is getting higher and higher, AIDS has a great infectiousness, the main way of transmission is mother-to-child transmission, blood transmission, sexual transmission of three ways, the transmission of AIDS is the need for certain conditions, take a look.

First, AIDS transmission mode

First, AIDS transmission mode

1, sexual contact transmission of AIDS incidence of the highest mode of transmission is sexual contact transmission. People who have had sexual contact with HIV patients can transmit the virus to them through bodily fluids.

2, mother-to-child transmission of the mother for HIV carriers, then he is pregnant, when the baby is born, the baby may be infected through the birth canal, may also be infected in the womb with the mother of HIV. When mothers of AIDS patients breast-feed their babies, they can also cause their babies to be infected with HIV.

We all know that the AIDS virus is present in the blood. When normal people come into contact with the blood of AIDS patients, it is possible to contract HIV. Do not use a line needle, shaver and so on, are prone to HIV infection.

Two, the spread of AIDS needs to meet the following conditions

Step 1: Quantity

HIV lives only in the body's white blood cells, which are found in blood, semen and vaginal fluids, so AIDS can be transmitted through blood transfusions, needle sharing and sex. HIV lives in breast milk, so it can be passed to the baby through breastfeeding. HIV has also been detected in the saliva of people with AIDS, but the amount is too small for transmission. There is a certain amount of HIV that can be transmitted to others.

Step 2: Quality

The virus is of high quality in the human body, but it dies soon after leaving the body and cannot spread AIDS. The time it takes to leave the body and die depends entirely on the HIV status. If a person with HIV bleeds, the HIV in it dies soon after the blood clots outside. The humidity and temperature of the outside world can affect the survival time of HIV.

3. Transmission route

HIV transmission from one person to another, in addition to a certain amount and quality, but also have a direct channel of transmission for AIDS transmission: there is the exchange of vaginal fluid, semen, blood activities.

4. Detox

The elimination of the virus from an infected or AIDS patient is a prerequisite for the spread of AIDS. HIV needs to be excreted through blood, semen, vaginal secretions, milk and other carriers.

Step 5 Survive

HIV is a very fragile virus, outside the human environment survival ability is weak, it is very sensitive to heat and drying. In a dry environment, HIV dies in 10 minutes and is inactivated in 60 degrees Celsius in 30 minutes. The virus leaves the body for a few minutes to greatly reduce the infectivity, the longer the time becomes weaker.

Step 6 Enter

Live HIV to infect another person, must be through a certain way, such as blood transmission, sexual transmission, mother-to-child transmission to enter another person's body.
