Bleeding in the hotel

First of all, before you use the razor, have you confirmed whether others have used it? Most razors in hotels are disposable. As long as no one else has used it, it is absolutely safe. What you said is used by others, which is different in nature. It's best not to use other people's used things in hotels. Although HIV is terrible, as long as it leaves human blood, the transmission rate is very low. If that person happens to be an AIDS carrier and scratches himself with a razor, if you continue to use it and then bleed, there is still a chance to get infected with it. But the chance of infection is very small. Because HIV can't survive in the air for a long time.
