Sweat from hepatitis B patients is not contagious. For hepatitis B patients, sweat does not contain the hepatitis B virus, which is mainly found in the patient’s blood, semen, vaginal secretions, etc. Therefore, routine contact with hepatitis B patients, such as talking, shaking hands, hugging, eating together, and group activities, will not infect them with hepatitis B. At present, the main transmission routes for hepatitis B are blood transmission, sexual contact transmission, vertical transmission from mother to child and other transmission routes, such as occupational exposure of health care workers and transplantation of organs containing hepatitis B virus, including hemodialysis and other medical transmission can be transmitted.
