The human-to-human transmission reported in SARS-CoV-2 infection occurs mainly through droplet or direct contact. Due to this finding, frontline health care workers should follow stringent infection control and preventive measures, such as the use of PPE, to prevent infection (110). The mental health of the medical/health workers who are involved in the COVID-19 outbreak is of great importance, because the strain on their mental well-being will affect their attention, concentration, and decision-making capacity. Hence, for control of the COVID-19 outbreak, rapid steps should be taken to protect the mental health of medical workers (229).
