Hepatitis B is one of the most widespread and dangerous viral infections affecting the liver. Despite advancements in medicine, Hepatitis B remains a silent global threat—many infected people do not show symptoms for years, allowing liver inflammation to progress quietly into fibrosis, cirrhosis, or even liver cancer.

Understanding who is at highest risk and how to prevent the disease is essential. This article breaks down the key facts every individual, parent, and healthcare-conscious reader should know.

I. What Is Hepatitis B?

Hepatitis B is a viral infection caused by the Hepatitis B virus (HBV). It targets the liver, causing acute or chronic inflammation.

There are two types:

• Acute infection: Short-term, may resolve on its own.

• Chronic infection: Long-term, lasting more than 6 months; can lead to liver scarring, liver failure, or cancer.

The virus spreads when infected blood or bodily fluids enter another person’s bloodstream.

II. High-Risk Groups

Although anyone can contract HBV, certain groups face significantly higher risk:

1. Infants Born to HBV-Positive Mothers

This group has the highest likelihood of developing chronic infection because their immune systems cannot fight the virus effectively.

2. Healthcare Workers

Doctors, nurses, lab technicians, and emergency responders face constant exposure to blood and sharps injuries.

3. People Living With an Infected Family Member

Sharing razors, toothbrushes, or even surfaces contaminated with blood increases risk.

4. Individuals With Multiple Sexual Partners

HBV can be transmitted through sexual activity, especially when protection is not used.

5. People Who Inject Drugs

Shared needles or syringes are one of the fastest transmission routes.

6. Patients Undergoing Dialysis

Frequent exposure to medical equipment raises the risk of transmission.

7. Travelers to High-Prevalence Regions

Areas such as parts of Asia, Africa, and the Pacific Islands have high rates of chronic HBV.

III. Signs & Symptoms

Many people never show signs. When symptoms appear, they may include:

• Fatigue

• Jaundice

• Loss of appetite

• Dark urine

• Persistent nausea

• Right upper abdominal pain

Chronic Hepatitis B often remains silent for decades.

IV. Prevention Measures

Hepatitis B is almost entirely preventable. The following strategies are globally recommended:

1. Vaccination (Most Important)

The HBV vaccine is 95% effective.
Schedule:
✔ Birth dose
✔ Followed by 2–3 additional doses

Adults can vaccinate anytime.

2. Practice Safe Sex

Use condoms and avoid risky sexual behaviors.

3. Avoid Sharing Personal Items

Razors, clippers, toothbrushes, and needles should never be shared.

4. Safe Piercing & Tattooing

Ensure equipment is sterilized and licensed.

5. Screen Pregnant Women

Early detection prevents mother-to-child transmission.

6. Regular Testing for High-Risk Groups

Blood tests include HBsAg, anti-HBs, and anti-HBc.

V. When to See a Doctor

Seek medical advice if you:

• Have been exposed to infected blood

• Show signs of liver issues

• Are pregnant (HBV screening is mandatory)

• Have a family history of liver disease
