French hospital staff antibody study reveals infection patterns

NCT ID NCT04481529

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tested over 1,500 hospital workers in four French hospitals for COVID-19 antibodies to see how many had been infected. Researchers compared infection rates among staff in COVID-19 units, other care areas, and non-care roles, and across regions with different outbreak intensities. The goal was to understand exposure risks and help protect healthcare workers in future waves.
