COVID-19 is an emerging disease caused by highly contagious virus called SARS-CoV-2. It caused an extensive health and economic burden around the globe. There is no proven effective treatment yet, except certain preventive mechanisms. Some studies assessing the effects of different preventive strategies have been published. However, there is no conclusive evidence. Therefore, this study aimed to review evidences related to COVID-19 prevention strategies achieved through contact tracing, screening, quarantine, and isolation to determine best practices. 

To support the existing local and national COVID-19 prevention program with tangible evidence, we conducted a systematic review on global strategies for COVID-19 prevention through contact tracing, screening, quarantine, and isolation. We aimed to answer issues related to alternative strategic implementation and effectiveness in the prevention of the disease or death.

The following key questions were considered:

1. Is contact tracing, screening, quarantine, and isolation effective to control the COVID-19 outbreak? 
2. Is there difference in the effectiveness of contact tracing, screening, quarantine, and isolation in different settings?
3. How and when these strategies should be applied to control the COVID-19 outbreak?
