Lessons learned from three Southeast Asian countries during the COVID-19 pandemic

Several scholars have focused on the COVID-19 case studies in Europe and USA, leaving the people in Southeast Asia with little information about the lesson learned from their own case studies. This study aims to analyses case studies through the SEIR model in three Southeast Asia countries including Singapore, Malaysia, and Indonesia. The SEIR model incorporates two type measures including social behavior and lockdowns as well as hospital preparedness. The SEIR model reveals that Malaysia, despite its relatively low testing capacity but with the application of the national lockdown, can slash the coronavirus transmission while Indonesia has still struggled to contain the COVID-19 flow owing to partial lockdowns. Singapore, at one hand, can successfully contain the coronavirus due to the national lockdowns, and the better healthcare system. With this point in mind, it is not surprised that Singapore has very low fatality rates and significantly low cases after lockdowns. Better preparedness, the full lockdowns, and sufficient testing capacity are keys to control the COVID-19 flow, especially if the development of vaccines or distribution of respective vaccines is under progress.
