The torrid coronavirus summer across the Sun Belt is easing after two disastrous months that brought more than 35,000 deaths. Whether the outbreak will heat up again after Labor Day and the resumption of school and football remains to be seen. Seven of the nine states along the nation’s Southern and Western rim are seeing drops in three important gauges — new deaths, new cases and the percentage of tests coming back positive for the virus. Alabama is the only state in the region to see all three numbers rising; Mississippi’s deaths are up, but positive rates and cases are dropping.
