Slide1

Hepatitis B

Hepatitis B is a pathogen, which causes liver disease and inflammation of the liver.Slide2

History

In 1963, Dr Baruch

Blumberg

accidentally discovered an antigen that detected the presence of hepatitis B in blood samples.

Dr

Blumberg

and his team identified a strange antigen from a blood sample of an Austrian Aborigine.

They decided to name this antigen the Australia antigen.

In 1967, further research showed that this was the hepatitis B causing antigen, which was then officially recognised.Slide3

Symptoms

Signs and symptoms of HBV usually appear about one to four months after you've been infected. Symptoms include:

Abdominal pain

Dark urine

Fever

Joint pain

Loss of appetite

Nausea and vomiting

JaundiceSlide4

Diagnosis

Hepatitis B is usually diagnosed with routine or requested blood screening tests such as:

Hepatitis B Surface Antigen Test

This test shows if you're contagious. A positive result means you have HBV and can spread the disease. A negative result means you don't have HBV.

Hepatitis B Core Antigen Test

This shows whether you are currently infected with HBV. A positive result indicates that you have chronic hepatitis B.Slide5

Antibody Hepatitis B Surface Antigen Test

Shows whether you're immune to HBV. A positive test shows that it is very unlikely you will contact hepatitis B.

Liver Function Tests

These check your blood for heightened enzymes from your liver. HBV can mimic the symptoms of other conditions such as liver diseases.Slide6

Contraction

You may get HBV if you:

Get a tattoo or a piercing with unsterilised tools.

Share needles with an infected person.

Have unprotected sex with an infected person.

Share personal items,

like toothbrushes and razors with an infected person. Slide7

Prognosis

The hepatitis B virus usually only stays in the system for around one to three months and is therefor an acute infection.

In severe cases, if a person remains infected they may develop complications such as liver cirrhosis or liver cancer.Slide8

Treatment

Chronic hepatitis B is not curable but it is treatable.

Treatments include:

R

eceiving

an injection of hepatitis B immune globulin within 12 hours of coming in contact with the

virus.

Antiviral medications .

Liver transplants.Slide9

Prevention

The hepatitis B vaccine is typically given as three or four injections over six months. You can't get hepatitis B from the vaccine

.

Other ways to reduce your risk of HBV include

:

Before you travel to a foreign country, ask your doctor about the HBV vaccine.

Know the HBV status of any sexual partner.

Be cautious about getting piercings and tattoos .

Stop using illicit drugs.Slide10

Future

Other drugs to treat hepatitis B are

being developed.Slide11

Facts

This year alone, 10 to 30 million people will become infected with HBV.

Infection kills one person every 30-45 seconds .

HBV is about 10 times more prevalent than HIV in the world.Slide12
