The speed of transmission intervention is critical for reducing ICU patients and healthcare staff depletion.

“whether or not you're a city that is totally overrun in terms of having patients on ventilator in the hospital beds and depletion of healthcare staff is very much depends on how quickly you picked up transmission so in Wuhan where transmission went on for six weeks without people intervening it was a catastrophe so it was and we all heard the stories of what went on Wuhan in creating ten cities of hospitals as opposed to Guangdong where they picked it up after a week and there were 20 people in the ICU so it's night and day”
