There are a few US states that show some upward momentum in new cases (with relatively stable hit ratios). Nothing conclusive yet. But they should be on the radar again:

1) Georgia

the 7-day MA is edging up, but still below the mid-April peak (w same trend in hospital data...)

2) North Carolina:

local health officials are recognizing that numbers are worse, and could impact the reopening process:

3) Wisconsin

lots of reporting of busy beaches etc around the holiday weekend. time will tell if it has an effect:

Local reporting seems to think the increase is real, but not yet alarming:
