Psychological Status of Opioid Treatment Service Staff in Tehran, the Epicenter of COVID-19 Outbreak in Iran: A Longitudinal Cohort Study

Abstract

Background: Coronavirus disease 2019 (COVID-19) is a severe acute respiratory syndrome that emerged in early December 2019. Global proliferation, abrupt increases in confirmed cases, and the risk of self-infection have caused significant stress and anxiety among staff working in opioid treatment services (OTS). The aim of our study was to determine the psychological status of staff working in OTS during the outbreak period of COVID-19 in Tehran.
