This is called acute hepatitis B.You can have hepatitis B and not know it. You may not have symptoms. If you do, they can make you feel like you have the flu. But as long as you have the virus, you can spread it to others.

    Sometimes the virus causes a long-term infection, called chronic hepatitis B. Over time, it can damage your liver. Babies and young children infected with the virus are more likely to get chronic hepatitis B.
