Hepatitis B virus
Hepatitis B virus (HBV) is a contagious virus that affects the liver. It spreads through contact with infected blood, sexual contact, or from mother to baby during childbirth. Once infected, some people recover fully, but others develop a long-term (chronic) infection that can lead to serious liver problems like cirrhosis or liver cancer. Many people may not show symptoms initially, but can still transmit the virus. Vaccination is effective in preventing HBV infection. Regular medical care and monitoring are important for those with chronic hepatitis B to manage health risks.
