Introduction
Hepatitis B is a liver infection caused by the hepatitis B virus (HPV). There are two other types of hepatitis viruses: hepatitis A and hepatitis C. Hepatitis can cause liver inflammation. Hepatitis B is a curable disease that can be prevented with a vaccine. It can affect a person either for a few weeks, causing less damage or chronic infection, lifelong sickness.
The seriousness of the contagion is defined by the spread of the virus in the liver. If the infection is widespread in the liver, it then causes chronic hepatitis or cirrhosis. WHO estimated that the African region is the highest infected area of hepatitis, with 6.2% of the population infected.
