The COVID-19 Resource Centre, established by Elsevier in January 2020, provides free information in English and Mandarin on the novel coronavirus. The centre is hosted on Elsevier Connect and grants permission for all COVID-19-related research to be immediately available in PubMed Central and other public repositories, with unrestricted reuse and analysis rights. The Psychiatric–Medical Comorbidity section focuses on the prevalence and impact of psychiatric disorders in patients with chronic medical illnesses and vice versa. A study on long-term psychiatric morbidities among SARS survivors at 30 months post-outbreak found a high cumulative incidence of psychiatric disorders (58.9%) and a current prevalence of 33.3%. PTSD was the most prevalent condition, followed by depressive disorders. The study highlights the need for enhanced preparedness and competence in detecting and managing psychological sequelae of future infectious disease outbreaks. The study, conducted at United Christian Hospital in Hong Kong, assessed psychiatric outcomes in 90 SARS survivors using the Structured Clinical Interview for DSM-IV, Impact of Events Scale–Revised, and Hospital Anxiety and Depression Scale. The results showed that 58.9% of survivors had a cumulative incidence of psychiatric disorders, with PTSD being the most common (47.8%). The study also noted higher rates of PTSD among healthcare workers (HCWs) compared to non-HCWs. The findings suggest that the SARS outbreak should be considered a mental health catastrophe, emphasizing the importance of comprehensive management of psychiatric comorbidities in survivors.The COVID-19 Resource Centre, established by Elsevier in January 2020, provides free information in English and Mandarin on the novel coronavirus.
