The Taiwanese government, specifically PTH, was successful in controlling and preventing Delta-SARS-CoV-2 spread through epidemic investigation, rapid gene sequencing, rapid expanding isolation measures, expanding screening of the COVID-19 antigen for people who lived in regional villages, rapid COVID-19 vaccination, and short regional lockdown and travel restrictions, leading to no new cases of Delta-SARS-CoV-2 infection within the community since 26 June, 2021. Here, PTH is linked to COVID-19.
