> In an outbreak on an Australian cruise ship called the Greg Mortimer in late March, the passengers were all given surgical masks and the staff was given N95 masks after the first case of Covid-19 was identified. Mask usage was apparently very high, and even though 128 of the 217 passengers and staff eventually tested positive for the coronavirus, 81% of the infected people remained asymptomatic.

Does anyone know what the baseline to compare with is? What was the rate of symptoms in Diamond Princess?
