Understanding Hepatitis B: A Comprehensive Guide

What is Hepatitis B?

Hepatitis B is a viral infection that affects the liver. It's caused by the hepatitis B virus (HBV), which can be transmitted through contact with infected blood, semen, or other bodily fluids. The virus attacks the liver and causes inflammation, leading to damage and potentially even death.

There are several forms of HBV, including acute and chronic infections. Acute infection is a short-term illness that usually resolves on its own within 6 months, while chronic infection can last for years or even decades.

How is Hepatitis B Transmitted?

Hepatitis B can be transmitted through various means, including:

- Direct contact with infected blood or bodily fluids

- Sharing needles or syringes contaminated with the virus

- Mother-to-child transmission during childbirth

- Sexual contact with an infected person

What are the Symptoms of Hepatitis B?

The symptoms of hepatitis B can vary depending on the severity of the infection. In some cases, there may be no noticeable symptoms at all.

Common symptoms include:

- Fatigue

- Loss of appetite

- Nausea and vomiting

- Abdominal pain

- Dark urine or pale stools
