Today, I went to the barber's for a haircut and had it cut for about 15 minutes. Finally, when the barber used a razor to shave my forehead, I accidentally scratched my forehead and bled. I am worried that if the last person is AIDS, it is just like me, has been scratched and bleeding, will it be transmitted to me?
AIDS is mainly caused by sexually transmitted infections. As you describe this situation, though theoretically possible, there is no such coincidence in real life.
You should pay attention to regulating your own sexual behavior in your life to prevent some of your diseases. Others will not be infected. Just live at ease.
AIDS virus exists in the blood and body fluids of patients. The transmission route is infectious and infective. The hypothesis is not true in real life. If there is bleeding on the last guest, if the blood is on the knife, the hairdresser will clean the part in time, so you will not be infected with the virus. You should not worry.
If you go to a barber's shop to get a haircut and bleed, it depends on whether a patient in front has AIDS or not, and whether he has been bleeding. If there is AIDS in front of him, it also bleeds. If you have fresh blood on the razor and then scratch you, you may be infected.
