你好,HIV 见空气就没有,这个说法是不对的,实验数据是至少3天
HIV is fragile.When hiv is outside the body and in the environment, it quickly becomes damaged by minute changes in temperature, moisture and pH levels. When hiv becomes damaged, it CANNOT infect
3 days are under what conditions do you understand ? Generally speaking, it can only survive in the outside world a few seconds. Even in the left of the human body blood stream.
In room temperature, the liquid in the environment can live HIV 15 days, by HIV pollution items in 3 days at least there were contagious. In recent years, some research organization proof, from the body the blood the survival of the HIV virus from the body in the time to determine the amount of virus in the blood, the virus high content of blood, in wet cases, even in room temperature of placing 96 hours, still has the vigor. Even tip size a drop of blood, if meet fresh lymphocytes, and the AIDS virus is still in which it can be continuously copy, can still spread. Low levels of virus blood, after natural dry 2 hours, vitality lost; But the virus high content of blood, even if dry up 2-4 hours, once in the medium, meet lymphocytes, and still can enter it, continue to copy. So, which the HIV from the body the blood can cause infection. But HIV is very flimsy, fluid in HIV heated to 56 degrees 10 minutes inactivated. If boil can rapidly inactivated; 37 degrees, with 70% alcohol, bleaching powder, 10% 2% glutaraldehyde, 4% formalin, 35% isopropyl alcohol, 0.5% LaiSuShui and 0.3% h2o2, disinfectant deal with 10 minutes, can be inactivated HIV.
Although the AIDS virus will see seam drill, the viruses have weaknesses, they can only in the blood and body fluids of living cells to survive in the, in the air, the water can't survive and food, left the blood and body fluid, the virus will soon die. Only with the virus blood or body fluids from a personal body directly into another personal body to spread. It also and hepatitis b virus, into the digestive tract will be damaged by the protease in the digestive tract.
