The Infection of Healthcare Workers and the Reinfection of Patients by Omicron Variant — Jiangsu Province, China, December 2022 to January 2023

WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? Healthcare workers (HCWs) and previously infected patients (PIPs) may experience a wave of epidemic following the modification of the country’s coronavirus disease (COVID)-zero policy in China. WHAT IS ADDED BY THIS REPORT? As of early January 2023, the initial wave of the COVID-19 pandemic among HCWs had effectively subsided, with no statistically significant differences observed in infection rates compared to those of their co-occupants. The proportion of reinfections among PIPs was relatively low, particularly in those with recent infections. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Medical and health services have resumed normal operations. For patients who have recently experienced severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections, appropriate relaxation of policies may be considered.
