Background: COVID-19 was first declared as an international public health emergency and then a pandemic by the WHO. In this systematic review, the importance of isolation and contact tracing has been explained, and what kinds of practices exist in different countries are mentioned. Methods: A systematic review was conducted in accordance with the PRISMA and Cochrane guidelines by searching articles from major medical databases such as Google Scholar, PubMed/MEDLINE, Cochrane Library, EMBASE, CINAHL between Jan 1, 2020 and Apr 1, 2021. Observational and modeling studies written on contact tracing, screening, quarantine and isolation were included. Results: 27 observational and modeling studies were included. It was seen that rapid contact tracing to reduce the basic reproduction number (R0) from 3.11 to 0.21. Additionally, each new case requires an average of 36 people to be monitored. Since screening programs missed 75% of cases, high-level contact tracing should also be done simultaneously. Wide quarantine would prevent 79.27% deaths and 87.08% infections. Conclusion: Effective, rapid contact tracing is the cornerstone of an effective public health response in outbreaks. Its success depends on quickly identifying cases, gathering information from them about their last contacts, and tracing and isolating those contacts.
