Vietnam has refused to ‘live with Covid’ unlike some other countries, and controls Coronavirus making its own test kits and aggressively tracing and quarantining contacts with public support solicited with media notices on places frequented by confirmed infected persons.
Unlike the less-successful Korea which uses home quarantine, resulting in a constant stream of deaths, (522 up to Nov 28) Vietnam uses institutional quarantine, regional border restrictions and surgical lockdowns to completely kill outbreaks and bring infections to zero.
Vietnam has had only 35 deaths, no curfews and mild lockdowns (social-isolation) involving a stay at home request, closing bars and gyms.
Vietnam completely killed the first wave from Wuhan in Jan-Feb 2020, the second Wave from mainly European and other Asian nations that allowed community transmission and a third outbreak in Da Nang July – August 2020 after over a 100 days without a single confirmed case.
