National HIV Vaccine Awareness Day:Transmission & Prevention of AIDS


May 18 is National HIV Vaccine Awareness Day, a day created to recognize all those who have worked to develop an HIV vaccine. It is also a reminder to all of us that an HIV vaccine can help us prevent AIDS, so the development of this vaccine is an important piece of work for human health.

How is HIV transmitted?

Most people who are infected with HIV remain healthy and are able to live for many years with no symptoms or only mild illness. However, even when they appear healthy and feel healthy themselves, they are still able to transmit HIV to others and remain infectious for life.

 HIV is strictly host-specific and can infect humans and cause AIDS.

Under experimental conditions, HIV-1 can infect chimpanzees and HIV-2 can infect rhesus monkeys, but cannot cause disease in animals. HIV is generally transmitted through blood and semen, and the main transmission routes include:

1. Sexual transmission

HIV can be transmitted through sexual intercourse, more frequently among men who have sex with men, and through artificial insemination.

2. Blood transmission

HIV can be transmitted through receiving blood or organ donations from HIV-infected people, using HIV-contaminated blood products or sharing injection needles with HIV-infected people. In addition, medical and laboratory personnel who come into contact with body fluids or HIV cultures from HIV-infected patients are at occupational risk of HIV infection.

3. Mother-to-child transmission

Mothers of HIV-infected individuals can transmit HIV to their newborns in utero or during delivery.

NOTE: General human-to-human contact does not lead to the transmission of AIDS, so there is no need to be overly sensitive and fearful about it.

How to prevent HIV?

The process of treating AIDS is arduous, but preventing AIDS is much easier than treating it, and we can completely eliminate the transmission of AIDS if we do a good job of prevention.

1. Avoid unclean sexual intercourse

HIV is present in the blood, semen and vaginal secretions of AIDS patients, and can be transmitted through sexual intercourse. Not all sexual intercourse will lead to the transmission of the virus, but sex between men and the same sex can easily lead to wound breakage, resulting in a somewhat higher rate of HIV transmission.

You should avoid having multiple sexual partners and disordered private life, and always take safety measures when having sexual relations.

2. Avoid sharing personal items

Sharing personal items such as toothbrushes and razors with HIV patients, which have close contact with your own your wounds, may spread the virus to you.

Although this situation is relatively rare in the transmission of AIDS, it is still necessary to separate the use of personal items for the sake of health.

3. To formal institutions treatment to cure, ear piercing, tattoo

Informal medical clinics, beauty institutions and tattoo parlors may not be in place to sterilize the situation, and may even share apparatus with others. And you use to the tattoo props, beauty products, pedicure knives, syringes, etc., these items once in contact with blood and HIV, it is highly likely to give you the risk of infection.

4. Avoid drug use, sharing syringes

The way drugs are injected is the main cause of HIV infection among drug addicts. According to authoritative data surveys show that people who tie needles to use drugs are 50 times more likely to be infected with HIV than the general population. Many drug addicts suffer from AIDS and they use drugs through intravenous injection, which greatly increases the risk of infection.

You should also avoid donating blood at informal medical facilities, which also has the chance of sharing needles with people.
