Why hepatitis B very serious?
Hepatitis B is spread when blood, semen, or other body fluids from a person infected with the virus enters the body of someone who is not infected.
How serious is chronic (long-term) hepatitis B?
Chronic hepatitis B can develop into a serious disease resulting in long-term health problems, including liver damage, liver failure, liver cancer, and even death.
There were 1,649 deaths related to hepatitis B virus reported to CDC in 2018, but this is an underestimate.
How hepatitis B is curable?
A vaccine can prevent hepatitis B, but there's no cure if you have the condition. If you're infected, taking certain precautions can help prevent spreading the virus to others.
Why Hepatitis B is a “silent epidemic” ?
Because most people do not have symptoms when they are newly infected or chronically infected.
Thus, they can unknowingly spread the virus to others and continue the silent spread of hepatitis B.
For people who are chronically infected but don’t have any symptoms, their liver is still being silently damaged which can develop into serious liver disease such as cirrhosis or liver cancer.
How does it preventable and treatable?
The good news is that hepatitis B is preventable and treatable. There is a simple blood test to diagnose a hepatitis B infection.
Testing is the only way to know for sure if you are infected. There is a safe vaccine to prevent hepatitis B. There are effective drug therapies that can manage a chronic hepatitis B infection, and a cure is within sight.
What is Hepatitis B and Your Liver?
The liver is such an important organ that we can survive only one or two days if it completely shuts down - if the liver fails, your body will fail, too.
Fortunately, the liver can function even when up to 80% of it is diseased or removed. This is because it has the amazing ability to regenerate - or create - itself from healthy liver cells that still exist.
If your body were an automobile, your liver would be considered the engine. It does hundreds of vital things to make sure everything runs smoothly:

What's Structure of the Hepatitis B Virus?
The hepatitis B virus contains an outer envelope and an inner core.
What's the HBsAg antigen?
The outer envelope of the virus is composed of a surface protein called the hepatitis B surface antigen or "HBsAg".
The HBsAg can be detected by a simple blood test and a positive test result indicates a person is infected with the hepatitis B virus.
What's the HBcAg antigen?
The inner core of the virus is a protein shell referred to as the hepatitis B core antigen or "HBcAg," which contains the hepatitis B virus DNA and enzymes used in viral replication.
