If the maintenance with gloves is simply fine, know do maintenance for decades many old engineers, have not heard of who was infected with what virus. If you're an operator, just be sure to disinfect your instruments as required. The patient can also rest assured that many of the instruments are very intelligent without disinfection is not able to enter the treatment process.
HIV cannot remain active without being in a laboratory setting or in a closed environment (e.g., syringes, needles). It is important to note that HIV can survive for a relatively long period of time in the residual blood of a used hypodermic needle, and the use of a needle can directly enter the bloodstream of the human body; therefore, used hypodermic needles are very dangerous for HIV transmission, and used hypodermic needles should never be reused. The U.S. scientific research department after nearly a million times except for the clear transmission pathway of the special circumstances of contact exposure experiment results: be infected cases less than one in 10,000 cases.
HIV can survive for up to 15 days at room temperature in a laboratory environment of tightly controlled tissue cultures.
Some research organizations 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 remains viable even if left at room temperature for 96 hours without drying out. Even a drop of blood the size of a pinprick can still be transmitted if it encounters fresh lymphocytes in which HIV can continue to replicate.
Blood with a low viral load loses its viability only after 2 hours of natural drying, while blood with a high viral load, even after drying for 2-4 hours, can still enter lymphocytes and continue to replicate once it is placed in a culture medium and encounters them. But these cases are limited to laboratory settings.
According to the U.S. cdc report, even in a laboratory setting, viruses used for experiments in laboratories with much higher concentrations than human blood and body fluids drop ninety-nine percent of their activity after a few hours of drying. Therefore, the chances of infection from isolated blood containing HIV are virtually nil, except in a laboratory setting. HIV does not survive in air, water, or food, and in the outside world these viruses die very quickly, even in HIV-containing blood and other body fluids.
