Mapped: Global Hepatitis B Prevalence by Country (WHO 2026 Report)
Fresh WHO 2026 data maps chronic HBV burden — Africa/Western Pacific at 5-10%, Europe/Americas below 1%; rarely mapped disease with stark regional clusters.
Why it matters
The WHO Global Hepatitis Report 2026 is the first major HBV dataset update in years, covering 140 countries with 2022-base estimates. Africa accounts for 68% of new infections — a story that almost never gets mapped.
Map angle
Country-level choropleth of chronic HBV prevalence as % of population. Bubble variant for deaths or new infections per country. Strong Africa/Western Pacific vs Europe/Americas contrast makes for a visually striking post.
Urgency
Brand-new April 2026 WHO report. First-mover window for a rarely-covered global health topic.
