Quarantine for all asymptomatic strategy is incorrect in most high infection Covid-19 countries. Covid-19 surges in Italy (2020) and Taiwan (June 2022) are repeating the same mistakes made in Wuhan (China).

In addition. the practice of this strategy without using vaccine can solve vaccine shortages in poor countries problem. Educational Apps link is freely available in this book
