USA are not locking down shutting the economy. They seem to be enforcing mask wearing having empty stadiums at sports etc.
This is the problem with the high case numbers, I'm not sure how much avoidance is mandated rules or just population scared to gather. The latter is definitely on the minds of friends I have over there especially with the high rate of children being infected, and some of those getting very sick, although thankfully not dieing. And I will use the words getting sick as they are not just testing positive, some are having very severe symptoms leading to lack of eating and drinking for several days and needing medical intervention.
The reason I'm seeing in some states for the rapid spread is that anti vax sentiment also spreads in pockets like the virus itself, so certain towns have very high proportion of unvaccinated, despite the whole country having a generally high rate. This then means when it gets loose in those populations it spreads rapidly among them. You don't get the fire break in the chain in those areas that having 2 of 3 vaccinated offers.

Just for information my view is not based on either of those news reports but on what I've heard from friends over there. The news is just covering a similar topic.
