The novel Coronavirus disease 2019 (COVID-19) is an illness caused due to Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). The global pandemic was declared by the World Health Organization on 11th March 2020 and COVID-19 has become a clinical threat to the general population and healthcare workers worldwide. This review details the effects on medical staff as they are experiencing specific stressors. The available literature has emerged from only a few of the most affected countries. The majority of studies is focused on depression, anxiety and insomnia. According to studies, mental health problems are a common response to the COVID-19 pandemic. There is a clear need for both training and support programs, to improve the prevention strategies among clinicians. At this time, health-care workers are every country's most valuable resource. Therefore, there is a huge need to building proper strategies for minimising the psychological impact of the COVID-19 pandemic on healthcare workers. It is extremely important to identify risk factors that may help in developing adequate interventions for clinicians. The long-term psychosocial impact of this epidemic on mental health of medical workers remains to be evaluated.
