What is hepatitis B?

    Hepatitis B usually refers to hepatitis B viral infection. Under normal circumstances, hepatitis B is a liver infection caused by the hepatitis B virus (HBV), which can impair liver function and has specific transmission routes. It requires scientific prevention and management measures. Detailed analysis is as follows:

    The pathogen causing hepatitis B viral infection is the hepatitis B virus, which mainly spreads through three routes: blood, mother-to-child transmission, and sexual contact. For example, sharing needles contaminated with the virus, receiving blood transfusions that have not undergone rigorous testing, or a mother transmitting the virus to her fetus during pregnancy or childbirth. Ordinary daily contact, such as sharing meals, handshakes, or using household items together, does not transmit the virus, so there is no need for excessive concern. The impact of the virus on the liver varies after infection. Some individuals experience acute infection, which may present symptoms such as fatigue, loss of appetite, and dull pain in the liver area. Most healthy adults can recover naturally within several months relying on their own immune systems.

    In daily life, vaccination is the most effective way to prevent hepatitis B infection. Individuals who have not been vaccinated or whose antibody levels are insufficient should promptly complete the vaccination series. Those already infected should undergo regular monitoring of liver function and viral load, avoid alcohol consumption, staying up late, and excessive fatigue. Maintaining regular作息 (作息 should be translated as作息 here, but since it's repeated, it might be better to use "作息" as "rest and work patterns" or "daily routine") and following a light diet can help protect the liver and reduce the risk of disease progression.
