WHO Executive Director Mike Ryan urged governments to put in place strong public health measures to prevent a resurgence of coronavirus outbreaks in the future.
"If we don't put in place strong measures, strong public health measures now, when those movement restrictions and lockdowns are lifted the danger is that the disease will jump back up. We need to actively search for cases of the virus and we need to test very single suspect case. We don't need to test everybody. We need to focus on testing those who may have the virus."
A number of countries have introduced drastic restrictions including travel bans, school closures and stay home orders to fight the coronavirus spread.
Ryan says China, Singapore and South Korea have provided a model for other countries, where restrictions were coupled with rigorous measures to test suspected infection cases.
