First, if you really give people injections for no reason, you must have ulterior motives. I believe that each of us will have our own purpose in doing something, so if we stab others in the street at will, there must be ulterior motives. Whether we are really carrying the virus or to cause panic to others, this kind of behavior and practice is very bad. If we are caught, we must be severely punished.
Second, when shopping, try to go to places where people are not so concentrated. The epidemic is not completely over, so you should keep a certain distance from others when shopping. For crowded places, go as little as possible, wear masks when going out, and try to keep a certain distance from strangers whether you are in line or going to other places. There is no need to panic too much about this stranger's needle sticking. After all, such things are rare. It is impossible for everyone to have such a high chance to go out once. Such a thing will happen to themselves.
Third, according to internet rumors, the needle was pricked by one person. Although surveillance has been taken, the evidence is still insufficient. According to the narration of these two netizens, it may be that a man gave himself a needle, but he felt pain when he touched the other person, but he didn't think about the direction of the needle at that time. He didn't react until he felt the pain, and he began to be afraid when he saw the pinhole on his body. So, two netizens went to the local hospital, explained the situation to the doctor, let the girls check for themselves, and saw some drugs to block the virus, hoping it wouldn't be so miserable.
