Hepatitis B is a viral infection of the liver caused by the Hepatitis B virus (HBV). It can be acute (short-term) or chronic (long-term) and may lead to serious complications like liver cirrhosis, liver failure, and liver cancer if not treated properly.Hepatitis B is a major public health problem, especially in developing countries.
HEPATITIS VIRUS UNDER MICROSCOPE
How Does Hepatitis B Spread?
Hepatitis B spreads through contact with infected blood or body fluids.
Common modes of transmission:
- Unprotected sexual contact
- From infected mother to baby at birth
- Sharing needles, syringes, or razors
- Unsafe blood transfusion
- Tattooing or piercing with unsterilized instruments
- Accidental needle-stick injury (healthcare workers)

Types of Hepatitis B
1. Acute Hepatitis B
- Short-term infection
- Most adults recover completely
- Symptoms last less than 6 months
2. Chronic Hepatitis B
- Infection lasts more than 6 months
- More common if infected at birth or childhood
- Can progress to cirrhosis or liver cancer

Many patients may remain asymptomatic, especially in early stages.
Common symptoms:
- Fatigue and weakness
- Fever
- Loss of appetite
- Nausea and vomiting
- Abdominal pain (right upper side)
- Dark-colored urine
- Pale stools
- Jaundice (yellowing of eyes and skin)
Diagnosis of Hepatitis B
Diagnosis is done by blood tests, including:
- HBsAg – indicates current infection
- Anti-HBs – indicates immunity
- Anti-HBc – past or current infection
- HBeAg & Anti-HBe – viral activity
- HBV DNA – viral load
- Liver function tests (SGOT, SGPT, bilirubin)
- Ultrasound abdomen (to assess liver damage)
Treatment of Hepatitis B
Acute Hepatitis B
- Usually no antiviral treatment required
- Supportive care: rest, fluids, healthy diet
- Regular monitoring
Chronic Hepatitis B
Treatment depends on:
- Viral load
- Liver enzyme levels
- Liver damage
Antiviral medicines include:
- Tenofovir
- Entecavir
- Pegylated Interferon (in selected cases)
⚠️ NOTE :-
Treatment is usually long-term and supervised by a doctor.
Complications of Untreated Hepatitis B
- Chronic hepatitis
- Liver cirrhosis
- Liver failure
- Hepatocellular carcinoma (liver cancer)
Prevention of Hepatitis B
1. Vaccination
- Most effective method
- Safe and highly effective
- Given in 3 doses (0, 1, and 6 months)
2. Safe practices
- Use condoms
- Avoid sharing needles, razors, toothbrushes
- Ensure sterilized instruments
- Screen blood before transfusion
