Overview

Hepatitis B is a viral infection that affects the liver and is caused by the Hepatitis B virus (HBV). It spreads through contact with infected blood or bodily fluids, such as unprotected sex, sharing needles, or from mother to baby during childbirth.



While some people show no symptoms, others may experience fatigue, jaundice (yellowing of skin or eyes), dark urine, abdominal pain, or nausea. Risk factors include unsafe injections, unprotected sex, working in healthcare, and living in areas where HBV is common.

 

 

Vaccination is the most effective way to prevent Hepatitis B. It is safe and effective, and it’s recommended for all infants, healthcare workers, and anyone at risk of exposure to infected blood or bodily fluids.

 

 

There’s no cure for HBV, but chronic cases can be managed with antiviral medications to slow liver damage. Regular monitoring, a healthy lifestyle, and avoiding alcohol are key. Vaccination is the best way to prevent HBV infection.
