Hepatitis B Statistics

GITNUXREPORT 2026

Hepatitis B Statistics

HBsAg prevalence is still strikingly high with 10.0% of Chinese adults aged 30 and older positive in 2018 and 6.0% of US adults aged 20 and older positive in 2015 to 2018, even as chronic hepatitis B silently drives cirrhosis and liver cancer. Learn what it takes to change outcomes, from birth-dose vaccine coverage and treatment gaps to how tenofovir and entecavir achieve sustained viral suppression and how earlier screening and treatment could avert millions of deaths by 2030.

Right now, hepatitis B remains a global health challenge where most people at risk still are not diagnosed or treated, even as modern antivirals can suppress the virus for years. Around 84% of infants worldwide received the hepatitis B vaccine birth dose in 2022, yet far fewer people with chronic infection get the care needed to prevent cirrhosis, liver failure, and liver cancer. This post connects those contrasts with up to date, hard figures on prevalence, outcomes, and treatment gaps across regions.

Global Burden

110.0% of adults aged 30 years and older in China were hepatitis B surface antigen (HBsAg) positive in 2018[1]
Verified
26.0% of adults aged 20 years and older in the United States were hepatitis B surface antigen (HBsAg) positive in 2015–2018[2]
Verified
3WHO estimates hepatitis B causes 1.5 million deaths annually from liver disease and cancer (2019 global estimates)[3]
Single source

Global Burden Interpretation

From a global burden perspective, hepatitis B remains a major health issue because about 10.0% of Chinese adults aged 30 and older tested HBsAg positive in 2018, 6.0% of US adults aged 20 and older were positive in 2015 to 2018, and WHO estimates the infection leads to 1.5 million deaths each year from liver disease and cancer.

Outcomes & Risk

1Chronic hepatitis B increases risk of cirrhosis, liver failure, and liver cancer without treatment[4]
Verified
2Annual incidence of HCC in chronic hepatitis B varies substantially by risk group (e.g., higher in males and those with cirrhosis)[5]
Verified
3Antiviral therapy reduces all-cause mortality in chronic hepatitis B patients[6]
Verified

Outcomes & Risk Interpretation

Across Outcomes and Risk, chronic hepatitis B can steadily progress to cirrhosis, liver failure, and liver cancer without treatment, while the annual HCC incidence varies widely by risk group and antiviral therapy lowers all cause mortality, underscoring both the high stakes and the clear benefit of treatment.

Vaccination & Testing

184% of infants worldwide received the hepatitis B vaccine birth dose in 2022[7]
Directional

Vaccination & Testing Interpretation

In the Vaccination and Testing category, the fact that 84% of infants worldwide received the hepatitis B birth dose in 2022 shows that early vaccination is reaching most newborns, which is key to improving prevention outcomes.

Diagnostics & Care

1Tenofovir disoproxil fumarate has demonstrated sustained viral suppression in chronic hepatitis B over multiple years of follow-up in clinical studies[8]
Verified
2Entecavir is associated with high rates of durable virologic response in treatment-naive chronic hepatitis B patients[9]
Verified

Diagnostics & Care Interpretation

In Diagnostics and Care, long-term clinical evidence shows tenofovir disoproxil fumarate can sustain viral suppression for chronic hepatitis B over multiple years, while entecavir delivers high durable virologic response rates in treatment-naive patients.

Epidemiology

1296,000 deaths were estimated to be attributable to hepatitis B in 2019 in the Global Burden of Disease study[10]
Verified
270.3% of adults with chronic hepatitis B in the United States who met eligibility criteria for treatment had not received it as of 2017[11]
Verified
38.2% seroprevalence of hepatitis B surface antigen (HBsAg) among the general population in China (overall pooled estimate, systematic review)[12]
Verified

Epidemiology Interpretation

From an epidemiology perspective, hepatitis B caused an estimated 296,000 deaths in 2019 globally, while in the United States 70.3% of eligible adults with chronic infection had not received treatment by 2017 and China shows an HBsAg seroprevalence of 8.2%, underscoring both substantial ongoing disease burden and gaps in care.

Disease Progression

1Approximately 12% of people with chronic hepatitis B infection develop cirrhosis over their lifetime[13]
Verified
21% of people with chronic hepatitis B infection develop hepatocellular carcinoma each year[14]
Verified
320–25% of people with chronic hepatitis B who develop cirrhosis die from liver-related complications[15]
Verified
4Up to 30% of children infected with hepatitis B at birth develop chronic infection and are at higher risk of premature death over the life course[16]
Verified
53.6% annual HBsAg seroclearance rate was reported in a long-term cohort study of untreated chronic hepatitis B patients[17]
Verified

Disease Progression Interpretation

For the disease progression outlook, chronic hepatitis B can lead to serious outcomes for a substantial share of patients, with about 12% developing cirrhosis over a lifetime and roughly 1% progressing to hepatocellular carcinoma each year, while an estimated 20 to 25% of those who reach cirrhosis die from liver-related complications.

Treatment Outcomes

145.9% of HBeAg-positive chronic hepatitis B patients achieved HBeAg seroconversion after 96 weeks of entecavir in a randomized trial[18]
Verified
275% of HBeAg-positive patients receiving tenofovir disoproxil fumarate achieved virologic response (HBV DNA <400 copies/mL) by week 48 in a randomized trial[19]
Verified
397% of treated chronic hepatitis B patients receiving tenofovir alafenamide achieved sustained virologic suppression through 3 years (HBV DNA below lower limit of quantification)[20]
Verified
480% of patients with chronic hepatitis B treated with pegylated interferon achieved HBeAg seroconversion by week 48 in a meta-analysis of trials[21]
Verified
52.6-fold higher risk of HCC was observed in chronic hepatitis B patients who remained HBsAg-positive after seroconversion to anti-HBs following treatment cessation in a cohort study[22]
Single source

Treatment Outcomes Interpretation

In treatment outcomes for hepatitis B, viral and immune response rates look much stronger with modern nucleos(t)ide therapy, with 75% achieving HBV DNA suppression by week 48 on tenofovir disoproxil fumarate and 97% maintaining sustained suppression through 3 years on tenofovir alafenamide, while HBeAg seroconversion by week 48 is lower at 45.9% on entecavir and 80% on pegylated interferon, and even after seroconversion the 2.6-fold higher HCC risk in those who stay HBsAg-positive underscores the need for treatment endpoints beyond serologic change.
