Elimination, Containment, and Mitigation of COVID-19: A Personal Story about International Travels

Abstract

Background: The author and his wife report their unique experience of international travels during the COVID-19 pandemic, and discuss issues encountered in various countries. Methods: Narrated discussion of issues encountered during the COVID-19 pandemic. Discussion: “Zero-COVID” versus “Living with COVID-19” strategies are compared. Children have unique issues with COVID-19 pandemic. Evaluation of efficacy of the approaches in pandem-ic with time should consider the main types of interventions (e.g., border management/quarantine; physical distancing; mask use; case isolation, testing and contact tracing; vaccination). The key met-rics that can be used to compare the impacts of different strategies between the cities (e.g., cumula-tive case rate, cumulative mortality rate, case fatality risk, stringency index, economic performance) should be identified. Research in these approaches can help manage future pandemics in corona-viruses and emerging infections. The UK started with very loose mitigation ('herd immunity') and then switched to a suppression approach in 2021, followed by "living with the virus" approach. Whereas HK has been targeting towards elimination throughout. In between, countries like Singa-pore, Australia and New Zealand have shifted from zero-COVID strategy to living with the virus. It is easier to have effective social control measures in Hong Kong because it has clear borders and an authoritarian government, but it did not have a clear exit policy when Omicron spread.
