Johns Hopkins University said on Tuesday that the total number of confirmed coronavirus infections has reached 3,090,000 globally, with the US topping the list at 1,004,908 cases.

The number of infections in the US has doubled since it topped 500,000 on April 11. More than 20,000 new cases are still being confirmed daily, but the rate of increase is slowing.

The governor of the state of Florida indicated that he would make an announcement on Wednesday on whether to ease the state's lockdown and start reopening the economy.

New York City, the epicenter of the US outbreak, is expected to extend its lockdown beyond May 15. A remaining issue is ensuring sufficient learning opportunities for 1.1 million students from elementary to high school level.

Mayor Bill de Blasio told reporters on Tuesday that 247,000 iPads will be made available by the end of the month to allow students to take part in online classes.

He also said students who cannot complete the necessary courses for graduation or to advance to the next grade by June will be given options to study online over the summer.
