| Comment | It's a function of both infection rates and prevalence. We can tolerate higher infection rates (as we have been for a few months) if prevalence is low. Right now prevalence is rapidly increasing, so we have to act now - otherwise we'll be back where we were in March within weeks.
If this (and other measures) is successful and prevalence is reduced over the next few weeks, then we can tolerate opening things and an increase in infection rates again.
Also, in a few weeks we might be over the surge that's come about from schools and universities re-opening. |
