[8] "One of the most appreciated facts with regard to Vietnam’s countermeasures against the COVID-19 pandemic has been with regard to contact tracing which has gone up to three levels of contact tracing for any positive case which have been detected within the country. "[9] "realizing that an effective tracing system is the most critical component of the pandemic response, Vietnam immediately developed and implemented a thorough, accurate and centralized contact tracing system. Contacts for any person testing positive for the coronavirus are traced to three levels, and all of those people are tested immediately."[10] "Swift introduction of containment measures, combined with aggressive contact tracing, targeted testing, and isolation of suspected COVID-19 cases, helped keep recorded infections and death rates notably low on a per capita basis. "[11] Vietnam
