I'm not sure that suggestion was officially implemented for reporting purposes or was guidance for people who wanted to know if they had it.Testing frequency may be static, but has there been any impact in positivity rate, based on the new rule requiring two positive test results? (Or was that merely a suggestion, that wasn't implemented?)
Based on that site posted above, it looks like the positivity rate has been within a couple percent, ~8% +/- 2% just eyeballing it - for a month or so.
The positivity rate appears to have peaked in early January, but we've been in exponential growth of deaths since November. That the 2 would track upward at the same time makes sense to me - more cases translates to more deaths. But as the positivity rate has fallen, the number of deaths does not appear to have followed suit, except maybe the lag is more like 6 weeks or something.
