Bruce Aylward of the World Health Organization said that that world should "jump on this thing super fast", when asked by CNN if the rest of the world should adopt the all-society approach used by the Chinese government.

Aylward added that Chinese’s response was broader than their containment efforts in Wuhan and Hubei, saying, “The danger is looking at Wuhan and Hubei and say[ing] okay that is the Chinese approach – because actually that isn’t. That’s the exceptional part of the Chinese approach that is being applied in an area where you got community-level transmission right through the whole place.”

Aylward said countries should "isolate the contacts” and not let them "wander around and restart the transmission chains," which is what China did. Aylward’s exception, though, was that it was not necessary to lock down entire cities as China did.

“So I think the big message is: You can control this particular respiratory virus by using these measures. You don’t have to lock down cities is the big message from China in fact”, said Aylward.
