We have excellent data now? Please share the sources, because over here the lack of solid data seems to be the biggest obstacle to better policy making. We have official figures for COVID-19 deaths that only cover some cases and don't line up with the excess above seasonal rates. We have no idea how many people have already had it without major symptoms and estimates vary by an order of magnitude. We do not know the long term implications for those who have recovered in terms of immunity. Media sources are trying to work out fatality rates naively by dividing deaths so far by confirmed cases so far, ignoring the multi-week lag, so they are comparing incompatible figures and producing figures that may be very optimistic. Who is doing better than this right now?
