A serious liver infection caused by the hepatitis B virus that's easily preventable by a vaccine.







































What is the Hepatitis?

An inflammation of the liver.


Why Hepatitis B also called HBV, Hep B?

A serious liver infection caused by the hepatitis B virus that's easily preventable by a vaccine. And this disease is most commonly spread by exposure to infected bodily fluids.


How Hepatitis is spread to the world?

~Spreads by sexual contact

~Preventable by vaccine

~Treatable by a medical professional

~Requires a medical diagnosis

~Lab tests or imaging always required.


how it spreads called Hepatitis?

~By blood products (unclean needles or unscreened blood).

~By having unprotected vaginal, anal or oral sex.

~By mother to baby by pregnancy, labour or nursing.


Which Symptoms of Hepatitis Requires a medical diagnosis?

Symptoms are variable and include yellowing of the eyes, abdominal pain and dark urine.


Some people, particularly children, don't experience any symptoms. In chronic cases, liver failure, cancer or scarring can occur.


How Hepatitis treatment depends on severity?

The condition often clears up on its own. Chronic cases require medication and possibly a liver transplant.


How is hepatitis B is caused by?

Hepatitis B is a vaccine-preventable liver infection caused by the hepatitis B virus (HBV).


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:


Which Stores vitamins sugar and iron?

Liver

Stores vitamins, sugar and iron to help give your body energy.

Controls the production and removal of cholesterol.

Clears your blood of waste products, drugs and other poisonous substances.

Makes clotting factors to stop excessive bleeding after cuts or injuries.

Produces immune factors and removes bacteria from the bloodstream to combat infection.


Releases a substance called "bile" to help digest food and absorb important nutrients

The word “hepatitis” actually means “inflammation” of the liver.


Thus, “hepatitis B” refers to inflammation of the liver caused by the hepatitis B virus.


With early detection and appropriate follow-up medical care, people living with a chronic hepatitis B infection can expect to enjoy a long and healthy life.


What is the Hepatitis B Virus?

The hepatitis B virus is a small DNA virus that belongs to the “Hepadnaviridae” family. Related viruses in this family are also found in woodchucks, ground squirrels, tree squirrels, Peking ducks, and herons.


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.
