Coronavirus Disease-19 Testing Strategies for Patients and Health Care Workers to Improve Workplace Safety

Abstract 
Universal testing for COVID-19, at different time points as needed based on the contact history and/or symptoms would facilitate the prevention of horizontal transmission and creation of a safe workplace by identifying and isolating infectious cases. Given the continuing emergence of new viral strains with increased infectivity and severity and uncertainty of the efficacy of the available vaccines in providing protection against those new variants, the significance of widespread screening cannot be overemphasized while preparing workplaces worldwide for the safe return of employees and patients.
