Washington: US coronavirus deaths topped 45,000 on Tuesday doubling in a little over a week as cases climbed to over 800,000, according to a Reuters tally.

The United States has by far the world's largest number of confirmed coronavirus cases, almost four times as many as Spain, the country with the second-highest number.

Globally, cases topped 2.5 million on Tuesday, with North America accounting for one-third of all cases.

Deaths increased by more than 2600 on Tuesday alone with a few states yet to report.
