The risk of being infected with the hepatitis B virus is decreasing as the hepatitis B vaccine becomes more widely available to the population, and the risk of contracting hepatitis B is not as high as it could be from everyday contact. Hepatitis B virus can be transmitted through mother-to-child transmission, blood-to-body fluid transmission and sexual contact. Blood, body fluids, and sexual contact are the main factors of transmission in the population. For example, in the absence of protective antibodies against hepatitis B in the body, unprotected sexual intercourse with patients with acute or chronic hepatitis B and carriers of the virus still carries a risk of infection. However, with the popularization of the immunization program, the human body can produce protective antibodies after receiving the hepatitis B vaccine. It can protect people from hepatitis B virus infection, and at this stage, as long as the concentration of antibody titer in the body is sufficient, it is generally not easy to be infected with hepatitis B virus. Shaking hands and eating together with hepatitis B patients in daily life do not easily infect hepatitis B, so there is no need to panic. However, if you have not standardized vaccination against hepatitis B and do not have protective antibodies against hepatitis B, you can easily be infected with hepatitis B through tattooing, ear piercing, etc., so you should be vigilant. Long-term exposure to blood products, dialysis treatment, multi-partner sexual intercourse, etc., must be timely testing of the body’s antibody level, if low, you need to catch up on the vaccine to avoid infection with the hepatitis B virus.
