You think you haven't touched other people's blood or body fluids. During the whole tattoo process, your wound has too many opportunities to contact those. You only see the connecting wires, wrapped in plastic bags, but there are many things you can't see. As far as tattoo shops in China are concerned, it is basically impossible not to touch those things. Disinfection is for guests. You think tattoo parlors really have the ability to disinfect, and it won't go away. It is really necessary for every guest to be disinfected to the point of not spreading diseases.
Tattooed AIDS may be very small, AIDS is too weak, alcohol and sunlight can kill it, and it will not live long outside the human body. There are n kinds of hepatitis, neither iodine nor alcohol can kill it, and it is difficult to kill it if it is not cooked for enough time. It must be steamed in a medical pressure cooker for a long time, so tattooed ears are most susceptible to hepatitis. Of course, not many people get hepatitis because of tattoos, but there is a probability.
In addition, for your reference, although tattoo needles are disposable, those are made by small manufacturers and family workshops that make tattoo needle equipment in these places in Zhejiang. Just train an old woman for a few days. No products, no disinfection, no cleaning. It is still a problem, unlike the mandatory standards of medical device countries.
Generally speaking, there are not many infectious diseases with tattoos, but they are all possible. You are really worried. It's no use asking here. Going to the hospital for examination is the most scientific. Testing for AIDS and hepatitis is not expensive. You don't want to spend money to donate blood That will check whether you have a series of problems such as hepatitis, AIDS and syphilis (don't tell the blood donor that you have a tattoo recently, others can refuse you). You know there's no point in asking. Without the test data, no one dares to give you a conclusion even if you look for AIDS and hepatitis experts all over the country.
Ok, I wish you health!
