Abstract
In South Korea, where successful epidemics have been implemented by the follow-up survey management (containment) of COVID-19-infected persons, the number of infected persons has increased rapidly, and a re-epidemic trend is emerging. The South Korean government is strengthening epidemic prevention activities, such as raising the social distance to the metropolitan area to four levels and raising the vaccination rate. The public is complaining of dissatisfaction with the atrophy of socio-economic activities and distrust of epidemic prevention policies. Australia started with an incidence similar to that of South Korea, but its social activities are more flexible than South Korea and the incidence is maintained at around 0.1 per 100,000 people. As a result of comparing the differences between the two countries, focusing on the OxCGRT Stringency Index of Government Response, it was found that Australia effectively regulates the amount of infection by high-intensity intermittent mitigation and subsequent allowance of social activities. South Korea also recommended confirming a high-intensity intermittent mitigation policy, as in Australia, until community herd immunity by vaccination is formed at this stage.
