About

This canvas is a comprehensive Hepatitis A epidemiological dashboard that analyzes U.S. outbreak patterns, demographic risk factors, and prevention effectiveness from 2011–2023 CDC surveillance data. It features three visualization blocks that feed from a central dataset: an annual cases trend chart showing the dramatic 2019 peak and subsequent 91% decline, a demographic risk analysis comparing infection rates by age group and case attribution by risk factor (drug use, homelessness, travel), and a prevention methods effectiveness ranking that highlights vaccination as the gold standard (97% effective) versus ineffective measures like alcohol-based hand sanitizers.
