I went to the bathroom in a chaotic public place, and I was accidentally scratched by the door lock

What are you worried about? AIDS? Hepatitis B? Or is it just a fear of getting infected?

If it is the first case, then you can rest assured, AIDS is mainly transmitted through sexual intercourse, blood transfusion, mother-to-child transmission, even if someone is sick and gets their own blood on the door lock, HIV can only survive in the air for about a minute, and it is almost impossible to infect you! Hepatitis B is similar to this one! It spreads more harshly and generally won't infect you!

Other infections don't matter!! Generally, the resistance of one's own body can kill those viruses! If you are not at ease, you can check the HIV antibodies, hepatitis B five items, and do a blood routine!

It doesn't cost a few bucks, but it will take a while for them to develop antibodies (in the case of you are infected, of course), and what to do later, when you are scratched, rinse with plenty of water and squeeze out some blood at the same time. This can prevent it! Of course, as said upstairs, it is better to pad it with a paper towel in an unclean place, which is safer!

It's better to go to the doctor in the future, it's best to bring a wrap of tissues to what song hall or something, wipe it at any time, and the doorknob can also be used to pad, which is convenient and very hygienic
