# Clinical progress note: Hepatitis A virus

## TL;DR

Hepatitis A virus remains a public health issue in the U.S., despite vaccination progress, with outbreaks highlighting inequities and the need for continued prevention efforts.

## Contribution

The paper emphasizes the importance of addressing vaccine inequities and leveraging hospitalization to prevent HAV resurgence.

## Key findings

- Recent outbreaks show HAV can re-emerge due to vaccine coverage gaps.
- Hospitalization is a key opportunity to improve protection for at-risk populations.
- Equitable vaccine access and surveillance are essential to prevent resurgence.

## Abstract

Despite a decline in hepatitis A virus (HAV) incidence following vaccine introduction, HAV remains a public health concern in the United States. Recent multi‐state outbreaks have demonstrated that HAV can re‐emerge and highlight inequities in vaccine coverage or access, outbreak response, and in those with social or health risk factors. Continued investment in prevention, particularly vaccination and surveillance, is essential to prevent resurgence. Hospitalization offers a critical opportunity to address these gaps and provide equitable protection for at‐risk populations.
