Point 1: caused by external force. The so-called external force refers to sexual behavior, also known as high-risk sexual behavior. Because there are many ways of transmission of hepatitis B, not only through blood, but also through male semen and female vaginal secretions.
Therefore, it is necessary to remind everyone that although our body will produce antibodies to hepatitis B virus after the hepatitis B vaccine, it will gradually weaken over time. Moreover, the vaccine is not omnipotent, but it plays a preventive role. If you don't pay attention at ordinary times, you will be infected through other channels.
Therefore, remind all friends who have been vaccinated against hepatitis B: You can live freely and make more friends, but you must not indulge yourself, especially in sexual life. If you don't take safety measures, you may get hurt.
The second point: micro-shaping. Now more and more people love beauty. Since the appearance of micro-plastic surgery, many fairies feel that the face given by their parents is really not perfect, their noses need to be raised a little, their chins need to be pointed a little, and their eyes need to be bigger, so they will achieve these goals through many minor operations.
However, if the disinfection of surgical instruments is not in place, it may also lead to human infection with hepatitis B virus, and it is unintentional infection.
