Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). HBV can survive outside the body for at least seven days. During this time, it can infect a person if it enters his or her body. A person can be infected and pass on the virus without knowing it. Here are the causes and risk factors of hepatitis B. Causes
  • Sexual contact. You may get hepatitis B if you have unprotected sex with someone who is infected.
  • Sharing of needles. The reuse of needles and syringes can transmit hepatitis B.
  • Exposure to infected blood. If infected blood comes into contact with open sores of an uninfected person, this can spread hepatitis B.
  • Mother to child. Pregnant women infected with HBV can pass the virus to their babies during childbirth. However, the newborn can be vaccinated to avoid getting infected in almost all cases.
Some people are at a greater risk of exposure to the virus. This includes people who:
  • have multiple sex partners
  • inject drugs or share needles
  • have spent time in prison
  • live with or have close contact with a person with chronic hepatitis B
  • are exposed to blood at work (such as health care workers)
  • are hemodialysis patients
  • travel to countries with a high hepatitis B rate
