We all know that AIDS is caused by HIV, and many people are going to ask, how can we tell it exists when we can’t see it with the naked eye?
At room temperature, HIV in a liquid environment can survive for 15 days, and items contaminated with HIV are infectious for at least 3 days. In recent years, several research institutions have demonstrated that the survival time of HIV in isolated blood is determined by the amount of virus in the isolated blood, and that blood with a high viral content, when undried, is still viable even when left at room temperature for 96 hours. Even a pinpoint-sized drop of blood can still be transmitted if it encounters fresh lymphocytes in which HIV can continue to replicate.
Blood with low viral content loses its viability only after 2 hours of natural drying, while blood with high viral content, even if dried for 2-4 hours, can still enter and continue to replicate in lymphocytes once it is placed in the culture medium and encounters them. Therefore, isolated blood containing HIV can cause infection. However, HIV is very fragile, and HIV in liquid can be inactivated by heating to 56 degrees for 10 minutes. If boiled, it can be inactivated quickly; at 37 degrees, HIV can be inactivated by treating it with disinfectants such as 70% alcohol, 10% bleach, 2% glutaraldehyde, 4% formalin, 35% isopropyl alcohol, 0.5% lysol and 0.3% hydrogen peroxide for 10 minutes. Although HIV sees the seams, these viruses also have weaknesses; they can only survive in living cells in blood and body fluids, not in They cannot survive in air, water, or food, and left out of these blood and body fluids, these viruses will die quickly. The virus can only be transmitted when blood or body fluids with the virus pass directly from one person to another. It also, like the hepatitis B virus, is destroyed by proteases in the digestive tract once it enters the digestive tract. Therefore, contact in daily life, such as shaking hands, kissing, sharing meals, living in the same room or office, touching telephones, door handles, commode, touching sweat or tears, etc. will not give you AIDS.
HIV is tiny and hard to see with the naked eye, which creates a serious interference for HIV prevention. We hope that the above information will be helpful to you, and that we will work together to nip the HIV virus in the bud, so that we can all be healthy and safe!
