## TL;DR

A rare case of pneumonia caused by human mastadenovirus B55 was found in a French patient with no recent travel history.

## Contribution

This is the first reported case of HAdV-B55 in France without travel history, suggesting local circulation.

## Key findings

- HAdV-B55 was identified in a patient with pneumonia and diarrhea in France.
- The infection was detected retrospectively through fecal testing.
- The case indicates possible endemic presence of HAdV-B55 in France.

## Abstract

We report a rare case of pneumonia caused by human mastadenovirus (HAdV) B55 in France in a patient without recent travel history. HAdV-B55 infection was identified retrospectively after being detected in feces during an investigation for concomitant diarrhea. This case suggests possible silent endemic circulation of HAdV-B55 in France.
