On Monday, California recorded 9,480 new cases, and South Carolina found 1,738 new cases.On Tuesday, Oklahoma counted 585 new infections.On Wednesday, 2,946 new cases were found in Georgia, Arizona had over 4,800 new cases, West Virginia reported 78 confirmed and probable cases, and Montana reported 67 new infections.On Thursday, Oregon recorded 375 new cases, Arkansas reported nearly 900 new cases, and Tennessee had 1,575 cases.On Friday, North Carolina broke the record it had set on Wednesday for its highest single-day infections (1,843) with 2,099 new cases.

Texas counted 8,258 cases, breaking its record from Wednesday (8,076).What they're saying: "Right now, if you look at the number of cases, it's quite disturbing. We're setting records, practically every day, of new cases in the numbers that are reported. That clearly is not the right direction," NIAID director Anthony Fauci told medical journal JAMA on Thursday.Go deeper: Coronavirus cases skyrocketing among communities of color
