US Secretary of State Mike Pompeo said he expected a solution "in the coming weeks" that would allow travel to restart between the United States and Europe.

His comments came as the World Health Organization warned that the epidemic remained "intense" in the Americas while White House adviser Dr Anthony Fauci said the next two weeks would be "critical" in the US battle to suppress Covid-19.

Travel has been largely banned between the US and the EU since March due to the coronavirus outbreak.

"We have to make sure that we have all of the elements in place to reopen travel between the EU and the United States," said Mr Pompeo.

"I'm very confident that in the coming weeks, we'll figure that out."

However, the New York Times reported that the European Union was considering blocking US travellers as it reopens its borders to tourism due the continuing high number of infections in the States.

The WHO today said it expected coronavirus cases to hit 10 million worldwide in the next week, as it warned the virus was yet to peak in the Americas.

"In the first month of this outbreak, less than 10,000 cases were reported to WHO. In the last month, almost four million cases have been reported," WHO chief Tedros Adhanom Ghebreyesus told a virtual press conference.

"We expect to reach a total of 10 million cases within the next week."

Coronavirus has killed at least 477,500 people and infected nearly 9.3 million others since emerging in China last December, according to a tally from official sources compiled by AFP.

The WHO said that nearly half of all Covid-19 cases globally can be found in the Americas, and the numbers continue to climb, regional director for the Americas, Carissa Etienne, said.

As of 23 June, there have been more than 4.5 million Covid-19 cases and 226,000 deaths reported in the Americas, she said in a virtual briefing from Washington.

WHO emergencies director Michael Ryan warned that the virus was still raging in the Americas and needed a very aggressive response from governments to suppress the spread.

"The epidemic in the Americas, in general, is still intense. It's particularly intense in Central and South America," he said.

"We've seen a steady and worrying continuation of trend, with many countries experiencing between 25% and 50% rise in cases over the last week. 

"Unfortunately, the pandemic for many countries in the Americas has not peaked," he said, and was "likely to result in a sustained number of cases and continued deaths in the coming weeks".
