What is hepatisis b?

Hepatitis B is a liver infection caused by the hepatitis B virus (HBV). It can cause both short-term and long-term liver problems.

Short-term symptoms of hepatitis B can include:

* Nausea

* Vomiting

* Fatigue

* Joint pain

* Fever

Long-term complications of hepatitis B can include:

* Cirrhosis (scarring of the liver)

* Liver cancer

* Liver failure

Hepatitis B is spread through contact with infected blood or bodily fluids. This can happen through:

* Sharing needles or other drug paraphernalia

* Unprotected sex

* Contact with open wounds or sores

* Receiving blood or blood products from an infected person

Hepatitis B can be prevented by:

* Getting vaccinated

* Practicing safe sex

* Not sharing needles or other drug paraphernalia

* Getting tested for hepatitis B if you're at risk

If you're diagnosed with hepatitis B, your doctor may recommend antiviral medication to help slow down or stop the progression of the infection. Treatment may also help reduce your risk of developing long-term complications.
