The number of new Covid-19 cases in the United States last week rose 13% to more than 393,000, approaching levels last seen during the summer peak, according to a Reuters analysis.

The number of tests coming back positive for Covid-19 is topping 25% in several states in the U.S. Midwest as cases and hospitalizations also surge in the region, according to a Reuters analysis.

The United States set a one-day record with over 1 million coronavirus diagnostic tests being performed, but the country needs 6 million to 10 million a day to bring outbreaks under control, according to various experts.
