The US averaged more than 50,000 new coronavirus cases a day on a rolling seven-day basis on Tuesday for the first time since mid-August, with 16 states reporting their highest mean levels of daily infections since the start of the pandemic.
States revealed a further 46,647 positive tests for Covid-19 over the past 24 hours, according to Covid Tracking Project data, up from 43,124 on Monday and compared with 38,661 on Tuesday last week.
Owing to four consecutive days of more than 50,000 new infections from Wednesday to Saturday — the first such streak since mid-August — the seven-day rolling average of new cases rose to about 51,032 a day. That is the highest the metric has been since August 16.
Rolling seven-day averages for new cases were at record highs in 16 states on Tuesday, according to a Financial Times analysis of Covid Tracking Project data. All but five of those were states in the Midwest region, which has become the autumn hot spot for coronavirus in the US.
For the third time in four days, a record-equalling 19 states had seven-day averages of more than 1,000 new infections a day. Nearly all of these were in the Midwest or the Mountain subregion, as defined by the US Census Bureau.
Texas became the second US state to confirm 800,000 coronavirus cases since the start of the pandemic after revealing 5,210 new cases on Tuesday.
Wisconsin reported a record jump in cases, which the state’s health department put at 3,279 and Covid Tracking Project tallied at 3,428, owing to different methodologies.
Nationally, a further 669 deaths were attributed to coronavirus, up from 287 on Monday and compared with 634 on Tuesday last week. Florida (123), Texas (64) and North Carolina (43) had the largest daily increases in deaths, while Wisconsin (34) was the only state to report a record rise.
Over the past week, the US has averaged about 692 deaths a day, roughly around the lowest level since mid-June.
