The United States topped 62,000 new coronavirus cases on Thursday, the country’s highest daily count since it reported more than 66,000 cases on July 31.

Cases in the Midwest began to surge during October. On Thursday, Wisconsin, Ohio, Indiana, North Dakota, Montana, New Mexico and Colorado tallied new single-day highs for positive test results. Fourteen states exceeded their seven-day averages of new infections.

Here are some significant developments:

  • Two people involved with Democrat Joe Biden’s presidential campaign have tested positive for the novel coronavirus, officials announced Thursday.
