Hepatitis B is one of the most serious and most common infectious diseases in the world — and Nigeria carries one of the highest burdens of this disease anywhere on the planet. Yet despite its prevalence and severity, most Nigerians living with hepatitis B do not know they have it.
That silence is what makes hepatitis B so dangerous. For years — sometimes decades — the hepatitis B virus can live inside a person’s body, quietly destroying liver tissue, without producing a single symptom. By the time symptoms appear, many patients have already developed cirrhosis of the liver or liver cancer.
This article is designed to change that. Whether you have never heard much about hepatitis B, or whether you or someone you love has recently been diagnosed, this complete guide will give you the knowledge you need — written in plain, clear language, by the team at Omokos Diagnostics and Clinical Services Ltd in Benin City.
Key Fact: According to the World Health Organization (WHO), approximately 296 million people are living with chronic hepatitis B infection globally. Nigeria has one of the highest prevalence rates in sub-Saharan Africa, with estimates suggesting that 8 to 12 percent of the Nigerian population carries the hepatitis B virus.

1. What is Hepatitis B?
Hepatitis B is a liver infection caused by the Hepatitis B Virus (HBV). The word hepatitis simply means inflammation of the liver. There are several types of viral hepatitis — A, B, C, D, and E — each caused by a different virus. Hepatitis B is caused specifically by HBV, a member of the Hepadnaviridae family of viruses.
The liver is one of the most vital organs in the human body. It processes nutrients from food, filters toxins from the blood, produces proteins essential for blood clotting, manufactures bile for digestion, and performs hundreds of other critical functions. When the hepatitis B virus infects liver cells — called hepatocytes — it triggers the immune system to attack them, causing inflammation and, over time, damage to liver tissue.
There are two forms of hepatitis B infection:
- Acute Hepatitis B — a short-term infection lasting less than 6 months. Many adults who contract hepatitis B experience acute infection and clear the virus naturally through their immune response.
- Chronic Hepatitis B — an infection that lasts longer than 6 months. The immune system is unable to clear the virus, which remains in the body indefinitely. Chronic hepatitis B is a lifelong condition that requires monitoring and, in many cases, treatment.
Hepatitis B is between 50 and 100 times more infectious than HIV. It can survive outside the human body for up to 7 days on surfaces — and can still cause infection during that time. Understanding how it spreads is the first step in protecting yourself.
2. How is Hepatitis B Transmitted?
Understanding how hepatitis B spreads is essential for protecting yourself and your family. Hepatitis B is transmitted through contact with the blood, semen, vaginal fluids, and other body fluids of an infected person. It is not spread through casual contact.
Routes of Transmission
- Mother to Child During Childbirth (Perinatal Transmission) — This is the most common route of hepatitis B transmission in Nigeria and across sub-Saharan Africa. An infected mother can pass the virus to her baby during delivery through exposure to blood and body fluids. Babies infected this way have a 90 percent chance of developing chronic hepatitis B if not treated immediately.
- Unprotected Sexual Contact — Hepatitis B is a sexually transmitted infection. It can be spread through vaginal, anal, or oral sex with an infected partner. The risk is highest with unprotected penetrative sex.
- Sharing Needles or Sharp Objects — Sharing needles, syringes, lancets, or any equipment that draws blood with an infected person transmits the virus directly into the bloodstream.
- Unsafe Medical and Dental Procedures — Procedures involving non-sterile instruments, including some traditional practices, tattooing, body piercing, and scarification, carry a risk of hepatitis B transmission.
- Blood Transfusions — Receiving blood from an infected donor who has not been properly screened can transmit the virus. This risk has been reduced by blood screening programmes but remains a concern in some settings.
- Sharing Personal Items — Sharing razors, nail clippers, toothbrushes, or any item that may come into contact with blood can transmit the virus.
How Hepatitis B is NOT Transmitted
Hepatitis B is not spread through:
- Hugging, handshaking, or ordinary physical contact
- Sharing food, water, or eating utensils
- Coughing, sneezing, or being in the same room as an infected person
- Breastfeeding — provided the baby has received the hepatitis B vaccine and immunoglobulin at birth
- Mosquito bites or insect bites
Many Nigerians avoid people with hepatitis B out of fear of casual transmission. This fear is unfounded and leads to harmful stigma. Hepatitis B cannot be spread through everyday social contact. Education is the cure for stigma.
3. What Are the Symptoms of Hepatitis B?
One of the most dangerous characteristics of hepatitis B is that it is largely asymptomatic — meaning the majority of people infected with the virus experience no symptoms, particularly in the early stages of chronic infection. This is why so many Nigerians are infected without knowing it.
Symptoms of Acute Hepatitis B
When symptoms do occur during acute infection, they typically appear 1 to 4 months after exposure and may include:
- Yellowing of the skin and eyes — jaundice — caused by bilirubin accumulation
- Dark, tea-coloured or cola-coloured urine
- Pale, clay-coloured stools
- Severe fatigue and weakness
- Nausea, vomiting, and loss of appetite
- Abdominal pain or discomfort — particularly in the right upper abdomen where the liver is located
- Fever — usually mild
- Joint pain
Symptoms of Chronic Hepatitis B
In chronic hepatitis B, most people have NO symptoms for years or even decades. When symptoms eventually appear, they often indicate advanced liver disease:
- Persistent fatigue and weakness
- Abdominal swelling — ascites — from liver failure
- Jaundice in advanced stages
- Easy bruising and bleeding — the liver can no longer produce clotting factors
- Spider angiomas — small spider-like blood vessels visible under the skin
- Mental confusion — hepatic encephalopathy — when toxins accumulate in the brain
- Significant unintended weight loss
CRITICAL POINT: The absence of symptoms does not mean you are not infected. Millions of Nigerians have chronic hepatitis B with no symptoms whatsoever — and are unknowingly transmitting the virus to others. The only way to know your status is through testing.
4. Acute vs Chronic Hepatitis B — What is the Difference?
| Feature | Acute Hepatitis B | Chronic Hepatitis B |
| Duration | Less than 6 months | More than 6 months — often lifelong |
| Who gets it | Mostly adults infected for the first time | Mostly people infected in infancy or childhood |
| Symptoms | Often present — jaundice, fatigue, nausea | Usually absent for years or decades |
| Outcome | Most adults clear the virus naturally (90%+) | Virus remains — requires lifelong management |
| Risk of liver cancer | Low | Significantly elevated — up to 25% lifetime risk |
| Treatment needed | Usually supportive care only | Antiviral therapy in many cases |
| Transmission risk | Present while virus is active | Continuous — person is infectious throughout |
The likelihood of developing chronic hepatitis B is strongly related to the age at which infection occurs. Babies infected at birth have a 90 percent chance of developing chronic infection. Children infected between 1 and 5 years have a 25 to 50 percent chance. Adults infected for the first time have only a 5 percent chance of developing chronic infection.
This is why the hepatitis B vaccination at birth is so critically important. Protecting babies at birth dramatically reduces their lifetime risk of chronic hepatitis B and all its devastating consequences.
5. How is Hepatitis B Diagnosed?
Hepatitis B is diagnosed through blood tests. These tests detect specific antigens (proteins from the virus) and antibodies (proteins produced by your immune system in response to the virus). Understanding which test shows what helps you make sense of your results.
| Test Name | What It Detects | What a Positive Result Means |
| HBsAg (Hepatitis B Surface Antigen) | The outer surface protein of the hepatitis B virus | You are currently infected with hepatitis B — acute or chronic |
| Anti-HBs (Hepatitis B Surface Antibody) | Antibody to the surface antigen | You are immune — either from vaccination or from clearing a past infection |
| Anti-HBc IgM (Core Antibody IgM) | Recent immune response to the core protein | Recent or acute hepatitis B infection |
| Anti-HBc IgG (Core Antibody IgG) | Past immune response to the core protein | Past or chronic hepatitis B infection |
| HBeAg (Hepatitis B e Antigen) | Viral protein indicating active replication | High viral activity — highly infectious |
| Anti-HBe (Hepatitis B e Antibody) | Antibody to the e antigen | Reduced viral replication — lower infectivity |
| HBV DNA (Viral Load) | Actual hepatitis B virus genetic material | Measures how much virus is in the blood — used to monitor treatment |
| Liver Function Tests (LFTs) | Liver enzyme levels — ALT, AST, ALP, bilirubin | Assess degree of liver inflammation and damage |
The Most Important Test — HBsAg
The Hepatitis B Surface Antigen (HBsAg) test is the standard first-line screening test for hepatitis B. It is simple, affordable, and available at Omokos Diagnostics and Clinical Services Ltd in Benin City.
- HBsAg Positive — you are currently infected with hepatitis B
- HBsAg Negative — you are not currently infected. However, if you have never been vaccinated, you are at risk and should receive the vaccine.
Get your HBsAg tested today at Omokos Diagnostics. The test is quick, affordable, and could be the most important health decision you make this year. Walk in or book an appointment at www.omokosdiagnostics.com.ng
6. What Happens to the Liver in Hepatitis B?
In chronic hepatitis B, the liver is under continuous attack from both the virus and the immune system’s response to it. Over many years, this ongoing inflammation causes progressive damage:
| Stage | What is Happening | Timeline |
| Hepatitis (Liver Inflammation) | Liver cells are infected and inflamed. Most patients have no symptoms. | Years 1 to 10+ |
| Liver Fibrosis | Scar tissue begins to replace healthy liver tissue. The liver starts losing function gradually. | Years 5 to 20 |
| Liver Cirrhosis | Extensive scarring. The liver is severely damaged and hardened. Symptoms begin to appear. | Years 10 to 30 |
| Liver Failure | The liver can no longer perform its essential functions. Life-threatening complications develop. | End stage |
| Hepatocellular Carcinoma (HCC) | Primary liver cancer — one of the most common cancers in Nigeria. Often fatal when detected late. | Can occur at any stage of chronic infection |
Liver cancer caused by chronic hepatitis B is one of the leading causes of cancer death in Nigeria. It is largely preventable through vaccination, early detection, and treatment. Do not wait for symptoms.
7. How is Hepatitis B Treated?
Acute Hepatitis B
Most adults with acute hepatitis B do not require specific antiviral treatment. The immune system clears the virus naturally in more than 90 percent of adult cases. Treatment is supportive:
- Rest and adequate sleep
- High fluid intake to prevent dehydration
- Avoiding alcohol completely — alcohol accelerates liver damage
- Avoiding medications metabolised by the liver unless prescribed by a doctor
- Regular monitoring of liver function and viral markers
Chronic Hepatitis B
Not all patients with chronic hepatitis B require immediate antiviral treatment. Treatment decisions are based on viral load, liver enzyme levels, degree of liver damage, and other clinical factors assessed by a specialist.
When treatment is indicated, the approved antiviral medications for chronic hepatitis B include:
- Tenofovir (TDF) — the most commonly used first-line antiviral in Nigeria. Highly effective, well-tolerated, and available through the Nigerian government’s hepatitis programme.
- Entecavir — another highly effective antiviral option with low risk of resistance.
- Interferon alfa — an injectable medication used in selected patients. Less commonly used due to side effects.
- Tenofovir alafenamide (TAF) — a newer formulation with improved kidney and bone safety profile.
While current antiviral medications suppress the hepatitis B virus very effectively, they rarely completely eliminate it from the body. Treatment is therefore long-term — often lifelong — and requires regular monitoring.
Important: Treatment for hepatitis B should only be started and monitored by a qualified medical doctor or hepatologist. Never start, stop, or change antiviral treatment without medical guidance.
8. Can Hepatitis B Be Prevented?
YES — and this is perhaps the most important message in this entire article. Hepatitis B is almost entirely preventable. We have a safe, effective, and affordable vaccine that provides protection in more than 95 percent of people who receive the full course.
The Hepatitis B Vaccine
| Vaccine Detail | Information |
| Type of vaccine | Recombinant subunit vaccine — contains only HBsAg protein, not live virus |
| Effectiveness | More than 95 percent effective in preventing infection |
| Schedule for adults | 3 doses: at 0 months, 1 month, and 6 months (0-1-6 schedule) |
| Schedule for newborns | First dose within 24 hours of birth, followed by 2 more doses |
| Duration of protection | At least 20 years — likely lifelong for most people |
| Side effects | Mild soreness at injection site, occasional mild fever — very safe |
| Who should be vaccinated | Everyone who has not previously been vaccinated and is HBsAg negative |
Other Prevention Measures
- Use condoms consistently during sexual intercourse
- Never share needles, syringes, razors, nail clippers, or toothbrushes
- Ensure medical and dental procedures are performed with sterile instruments
- Screen all blood before transfusion
- Test all pregnant women for hepatitis B and vaccinate newborns immediately after birth
- Inform sexual partners of your hepatitis B status so they can be vaccinated
The single most powerful intervention against hepatitis B in Nigeria is ensuring that every newborn receives the hepatitis B vaccine within 24 hours of birth. This birth dose prevents mother-to-child transmission — the most common route of hepatitis B infection in Nigeria.
9. Hepatitis B and Pregnancy — What Every Nigerian Mother Must Know
Hepatitis B and pregnancy is a topic of critical importance in Nigeria, where mother-to-child transmission is the most common route by which the virus spreads. Every pregnant woman in Nigeria should be tested for hepatitis B as part of her antenatal care.
- All pregnant women should have HBsAg tested early in pregnancy — ideally at the first antenatal visit
- If HBsAg is positive, the viral load (HBV DNA) should be measured to assess the risk of transmission to the baby
- The newborn must receive both the hepatitis B vaccine AND hepatitis B immunoglobulin (HBIG) within 12 to 24 hours of birth
- The combination of vaccine and HBIG is more than 95 percent effective in preventing mother-to-child transmission
- Mothers with high viral load may be offered antiviral treatment in the third trimester to further reduce transmission risk
- Breastfeeding is safe for babies who have received the birth dose vaccine and HBIG
If you are pregnant and have not been tested for hepatitis B, please do so immediately. At Omokos Diagnostics in Benin City, we offer HBsAg testing as part of our antenatal screening services. Early detection protects your baby.
10. Hepatitis B and HIV Co-Infection
Hepatitis B and HIV share the same routes of transmission and therefore frequently occur together in the same person — a condition called co-infection. In Nigeria, hepatitis B and HIV co-infection is a significant public health concern.
- People living with HIV are at higher risk of hepatitis B infection due to shared transmission routes and potential immune compromise
- Hepatitis B progresses more rapidly to cirrhosis and liver cancer in people who are also HIV positive
- Liver disease is now one of the leading causes of death in people living with HIV in Nigeria
- The good news is that some antiretroviral medications used to treat HIV — particularly tenofovir — also suppress hepatitis B, providing dual treatment benefit
- All people living with HIV should be screened for hepatitis B, and all people diagnosed with hepatitis B should consider HIV testing
11. Living With Hepatitis B — A Practical Guide
A diagnosis of chronic hepatitis B can feel overwhelming. But with the right knowledge, medical care, and lifestyle choices, millions of people live long, healthy, and productive lives with this condition. Here is your practical guide:
| Area | What to Do |
| Medical Monitoring | See a doctor at least every 6 months. Monitor liver function tests, HBsAg, HBV DNA, and ultrasound of the liver regularly. |
| Medication | Take antiviral medication exactly as prescribed. Never stop without medical advice — stopping treatment abruptly can cause severe liver flare. |
| Alcohol | Avoid alcohol completely. Alcohol dramatically accelerates liver damage in people with hepatitis B. |
| Diet | Eat a balanced, nutritious diet. Avoid processed foods, excessive fat, and heavily salted foods. Drink adequate water. |
| Exercise | Regular moderate exercise is beneficial. It supports liver health, weight management, and overall wellbeing. |
| Medications | Inform all doctors and pharmacists of your hepatitis B status. Some medications are hepatotoxic and should be avoided or used with caution. |
| Sexual partners | Inform sexual partners of your status so they can be tested and vaccinated. Use condoms consistently. |
| Household members | All household members and close contacts should be tested and vaccinated if not already immune. |
| Mental health | A hepatitis B diagnosis can cause anxiety and depression. Seek emotional support — from trusted family, a counsellor, or a hepatitis B support group. |
| Stigma | Hepatitis B cannot be spread through casual contact. You do not owe anyone an explanation of your health status. However, informing those who may be at risk is an act of care. |
12. Frequently Asked Questions About Hepatitis B
Can hepatitis B be cured completely?
Currently, there is no cure that completely eliminates the hepatitis B virus from the body in all patients. However, antiviral medications suppress the virus to very low or undetectable levels, prevent liver damage, and dramatically reduce the risk of liver cancer. Research into a functional cure is actively ongoing.
Can I get hepatitis B from eating at a restaurant?
No. Hepatitis B is not transmitted through food, water, or sharing utensils. You cannot get hepatitis B by eating food prepared by an infected person.
I was vaccinated as a child. Am I still protected?
Studies show that the hepatitis B vaccine provides long-lasting protection — likely 20 years or more. If you were vaccinated as part of a complete 3-dose course, you are most likely still protected. However, if you are unsure of your vaccination history or work in a high-risk environment, an Anti-HBs antibody test can confirm your immune status.
My HBsAg test is positive. What should I do right now?
Stay calm. A positive HBsAg result means you are currently infected with hepatitis B, but it does not tell you how serious your infection is. You need further tests — including liver function tests and HBV DNA — and a consultation with a doctor. Early management prevents progression to serious liver disease.
Is hepatitis B the same as hepatitis C?
No. Hepatitis B and hepatitis C are caused by completely different viruses. Hepatitis B has a vaccine; hepatitis C does not. Hepatitis C is curable with direct-acting antiviral drugs; hepatitis B currently has no cure but is well managed with antivirals. Both affect the liver and can cause cirrhosis and liver cancer if untreated.
Can I donate blood if I have hepatitis B?
No. People with hepatitis B — whether acute or chronic — are permanently deferred from blood donation in Nigeria and internationally. This is to protect blood recipients from receiving infected blood.
Where can I get tested for hepatitis B in Benin City?
You can get your HBsAg test done at Omokos Diagnostics and Clinical Services Ltd, located at Igo Community, After Ekehuan Barracks, Benin City, Edo State. Walk in or visit www.omokosdiagnostics.com.ng to book an appointment. Results are fast, accurate, and confidential.
Conclusion — Know Your Status. Protect Your Liver.
Hepatitis B is serious. It is common. It is largely silent. And it is killing thousands of Nigerians every year — most of them people who never knew they were infected.
But hepatitis B is also preventable. It is manageable. And with early detection and proper care, people with hepatitis B can live full, healthy, and long lives.
The single most important step you can take today is to know your status. A simple blood test — the HBsAg test — takes minutes and can tell you whether you are infected. If you are negative, you can protect yourself with the vaccine. If you are positive, you can begin the journey of monitoring and treatment that will protect your liver for the decades ahead.
Test today. Protect your liver. Protect your family.
