The coronavirus is receding in much of the United States, but spreading in communities with low vaccination rates, where contagious variants pose a new threat.
The country s declining COVID-19 case rates present an unrealistically optimistic perspective for half of the nation - the half that is still not vaccinated.
With the adjustment for vaccination, the national death rate is roughly the same as it was two months ago, while the adjusted rates in several states show the pandemic is spreading as fast among the unvaccinated as it did during the winter surge.
