Hepatitis B is a major public health problem in Nigeria — about 8% of Nigerians are infected, many without knowing it. It’s called a "silent killer" because it can damage your liver for decades with no symptoms, then cause liver cancer or cirrhosis. But it’s preventable with a vaccine and manageable with treatment.
1. What Is Hepatitis B?
null
2. Symptoms: Acute vs Chronic
Many people have NO symptoms, especially kids. That’s why testing is critical.
Acute Hepatitis B — 1 to 4 months after exposure:
70% of adults have symptoms, but most kids don’t
Fever, fatigue, weakness
Loss of appetite, nausea, vomiting
Abdominal pain, especially right upper side where liver is
Dark urine = tea/cola colored
Pale/clay-colored stool
Joint pain
Jaundice: Yellow eyes/skin — appears after other symptoms
Lasts few weeks to 6 months. Most adults clear it completely
Chronic Hepatitis B — Lasts >6 months, often decades:
Most have NO symptoms for 20-30 years while liver is slowly damaged
Later signs: Persistent fatigue, abdominal swelling, spider veins on skin, easy bruising/bleeding, confusion = hepatic encephalopathy
Complications: Cirrhosis = liver scarring, liver failure, hepatocellular carcinoma = liver cancer. 15-25% of chronic cases die from these
Red flags → See doctor ASAP: Yellow eyes + vomiting + confusion, severe abdominal swelling, vomiting blood, black tarry stool, extreme fatigue.
3. Treatment & Management: Your Core 4 Expanded + More
1. Get vaccinated
Why: Vaccine is 98-100% effective. Best prevention tool. Nigeria has it in routine infant immunization.
Schedule:
Babies: Birth dose within 24h — critical to stop mother-to-child spread, then 3 more doses at 6, 10, 14 weeks as part of Penta vaccine
Adults not vaccinated: 3 doses — 0, 1, 6 months. Fast track: 0, 7, 21 days + booster at 12 months if urgent
Post-exposure: Vaccine + HBIG = Hepatitis B Immunoglobulin within 24h if exposed
Who needs it: ALL babies, all unvaccinated adults, especially healthcare workers, s*x partners of Hep B+ people, people with multiple partners, HIV+, diabetics, travelers to endemic areas
Test first: Do HBsAg test before vaccinating adults. If already infected, vaccine won’t help. If already immune from past infection, no need.
Safe: Cannot give you Hep B. Made from part of virus, not live virus. Side effects = sore arm, mild fever 1-2 days.
2. Avoid sharing needles/razors
Why: Tiny invisible blood drops transmit HBV. Virus survives 7+ days outside body on surfaces.
How: Don’t share toothbrushes, razors, nail clippers, earrings. Ensure barbers use new blade per client — carry your own clipper. Avoid pedicure tools if not sterilized. Never share needles for drugs, tattoos, or injections.
Healthcare: Ensure new syringe + needle for every injection. Insist on screened blood if transfused.
3. Practice safe s*x
Why: Semen + vaginal fluids transmit HBV. Risk similar to HIV.
How: Condoms reduce risk 90%+. Limit partners. Both partners test. If partner is Hep B+, you get vaccinated. Avoid s*x during me**es or if ge***al sores present.
4. Limit alcohol
Why: Alcohol + Hep B = double damage to liver. Speeds up cirrhosis + cancer risk.
How: If HBsAg positive, avoid alcohol completely. Even “small” amounts harm inflamed liver. Also avoid herbal mixtures/agbo with unknown liver toxicity.
Other key management:
null
Monitoring if chronic Hep B: See doctor every 6-12 months. Tests: HBsAg, HBeAg, HBV DNA viral load, ALT, abdominal ultrasound, FibroScan.
4. Diagnosis: Know Your Status
Nigeria has high prevalence, so all adults should test once. Free at many govt hospitals during campaigns.
null
Interpretation:
HBsAg negative, Anti-HBs positive = Immune, protected
HBsAg positive >6 months = Chronic infection
HBsAg negative, Anti-HBc positive, Anti-HBs positive = Past infection, now immune
All negative = Susceptible, get vaccine
5. Prevention: Break the Chain
Birth dose vaccine — Most important. Nigeria’s coverage still
