Your situation is unlikely to spread. Reason: 1, the survival time of HIV in vitro is several hours to several days, which means that the virus will not survive in the external environment for a long time; 2. In order to retaliate against others, AIDS patients directly prick people with needles instead of putting them in Internet cafes; 3. In order to know whether it is infected or not, HIV antibody screening will be done after 3 months. If it is negative, there will be no infection. If it is positive, further tests will be done.
