Elsevier established a free COVID-19 resource center in January 2020, offering English and Mandarin information on the virus. The center is hosted on Elsevier Connect, and Elsevier grants permission for free access to its research in PubMed Central and other repositories for unrestricted reuse. A review of existing literature on mental health impacts of the COVID-19 pandemic found that anxiety, depression, and stress are common psychological responses. Symptoms of anxiety and depression were reported in 16-28% of cases, with 8% reporting stress. These symptoms may be linked to disturbed sleep. Factors influencing this risk include individual and structural variables. The literature is limited to a few countries, potentially not reflecting global experiences. The review highlights the psychological impact of the pandemic on the general population, healthcare workers, and vulnerable groups. Observational studies from China showed that anxiety and depression were more common in females, students, and those with symptoms suggestive of COVID-19. Social support and accurate information were protective factors. Healthcare workers faced significant mental health risks due to long hours, infection risks, and stress. Studies suggest the need for mental health services and support for vulnerable populations. Vulnerable groups include the elderly, homeless, migrant workers, and those with pre-existing mental health conditions. Therapeutic interventions include online mental health services, telemedicine, and community-based support. These strategies aim to provide accessible mental health care without increasing infection risks. However, their effectiveness and acceptance are yet to be fully validated. The review concludes that mental health is a critical concern during the pandemic, requiring coordinated efforts from healthcare professionals and systems. Further research is needed, especially in countries with less developed mental health infrastructure. Long-term mental health impacts may take weeks or months to emerge, necessitating ongoing attention and support.Elsevier established a free COVID-19 resource center in January 2020, offering English and Mandarin information on the virus.
