If you want to know what AIDS carriers can do, you must first know what AIDS virus is spread by. The first is blood transmission, which is easy to understand. For example, if you have an injection in a black clinic and the doctor gives you a needle used by an AIDS carrier, then you will be infected by blood. Followed by mother-to-child transmission, if the mother is HIV-positive, then the children born are either AIDS patients or AIDS patients. However, there are always exceptions to everything, and there are also things in which AIDS carriers give birth to healthy babies. Finally, it is spread through some kind of behavior.
So generally speaking, HIV must be transmitted by body fluids. As long as the spread of body fluids is stopped, AIDS carriers are actually no different from normal people. In fact, most AIDS patients can work, only a few types can't. First of all, soldiers, because if there is a war or accident in training. Blood transfusion is needed between comrades-in-arms and comrades-in-arms. Secondly, the catering industry, for example, you accidentally stained your fingers and blood dripped on the ingredients. In case this ingredient can't completely kill the virus during processing. In case you meet another diners with gastric ulcer. Then this diner will be infected because of you. There are also some enterprises and institutions that require higher physical conditions. You can basically do other work.
Because AIDS carriers are not infected, they are much better than infected people in health. So this is also the main reason why operators can do more work.
