Incidence and Disease Course of COVID-19 Infection Among Unvaccinated Patients Who Received Local Corticosteroid Injections.

Objective: There are concerns that local corticosteroid injections may increase the risk of COVID-19 infection because of the immunosuppressive effect of corticosteroids. This study aimed to examine the relationship between local corticosteroid injections and the risk of COVID-19 infection.

Design: The date and type of procedure as well as the dose and type of corticosteroids used in patients who underwent local corticosteroid injections within 1 yr after the first COVID-19 case in the country were examined retrospectively and recorded.
