This is certainly true...but to an extent. At some point the case numbers should also vastly begin to taper off. For example, here in Connecticut I think we've been hovering between like 800-1,000 cases per day...but given our rate of vaccinations and percent of adult population being vaccinated at some point these numbers should tail off.
After hovering between 3-5% daily positivity rate for the past 2-3 weeks we've been under 3% (and close to 2%) since the end of last week. Obviously positivity rate means more than case numbers but at some point case numbers should rapidly fall off. But according to Governor Lamont, the majority of cases were coming from the 18-30 crowd but now that vaccinations have been opened up for this group I am hoping over the next few weeks positivity rate should drop to around 1.5% and case numbers should drop by several-plus hundred.
