Abstract
WHAT IS ALREADY KNOWN ABOUT THIS TOPIC? The psychological impact of the large-scale infection of the population resulting from the end of lockdown measures in China during the coronavirus disease 2019 (COVID-19) pandemic is unknown. WHAT IS ADDED BY THIS REPORT? Among all participants, 55.7% had depression symptoms, with a significant difference between the infected and non-infected groups, and 30.1% had anxiety. Those who were young, unvaccinated, had lower incomes, and experienced chronic diseases were more likely to experience negative emotions. WHAT ARE THE IMPLICATIONS FOR PUBLIC HEALTH PRACTICE? Government officials should take into account the effect of policies on public sentiment during similar public health events and implement tailored community interventions to address any negative sentiment.
