The number of confirmed new coronavirus cases in the United States climbed to an all-time high of more than 50 thousand per day today.

With the infection curve rising in 40 of 50 states in a reversal that has largely spared only the Northeast.

In yet another alarming indicator, 36 states are seeing a rise in the percentage of tests that are coming back positive for the virus.

The surge has been blamed in part on Americans not wearing face masks or following other social-distancing rules as states lifted their lockdowns over the past few weeks.

According to a tally kept by Johns Hopkins University, the US recorded 50 thousand 7 hundred new cases today.

That represents a doubling of the daily total over the past month and is higher even than what the country witnessed during the deadliest phase of the crisis in April and May.

Data compiled by the COVID Tracking Project, a volunteer organization that collects testing information say all but 10 states are showing an increase in newly confirmed cases over the past 14 days.

The outbreaks are most severe in Arizona, Texas and Florida, which together with California have re-closed or otherwise clamped back down on bars, restaurants and movie theatres.
