Daily coronavirus deaths in the US surged to a three-month high of over 2,000 on Thursday and the number of cases passed 19 million globally, pushing many nations to further ratchet up restrictions in the battle against the pandemic.

The world's hardest-hit country, the United States, has seen a major coronavirus resurgence since the end of June, adding 2,060 deaths in 24 hours alone Thursday, a tracker by Johns Hopkins University showed.

But other corners of the globe were also marking grim milestones, with Mexico's official toll soaring above 50,000 dead and the continent of Africa hitting one million confirmed cases.

More than half of Africa's infections are in South Africa, which has the fifth highest number of infections in the world, after the US, Brazil, India and Russia.

Nevertheless the African continent remains one of the least affected, according to the official figures, with only Oceania registering fewer COVID-19 cases.

At least 19,000,553 cases and 712,315 deaths have been registered worldwide, figures compiled by AFP from official sources at 2300 GMT showed, driven by surges in Latin America and India.

The United States has recorded the most deaths with almost 160,000, followed by Brazil with nearly 100,000. Globally, 40 percent of all cases have been notched in the two countries.

Europe remains the hardest-hit region worldwide with more than 200,000 fatalities since the virus first emerged in China late last year.

As governments across the globe struggle to salvage economies ravaged by months of lockdown, many have been forced to look at new measures to curb outbreaks of COVID-19 since they lifted initial containment orders.

Such is the case in Europe where nations imposed new travel restrictions and containment measures with fears growing over a second wave of infections.

In Australia, the second-largest city Melbourne entered the country's toughest lockdown yet on Thursday, closing non-essential businesses and requiring hundreds of thousands more people to stay home.

Germany is the latest to introduce mandatory tests for travelers returning from designated risk zones, starting on Saturday, as fears grow over rising case numbers blamed on summer holidays and local outbreaks.

Germany's list of "risk zones" currently includes most non-EU countries, as well as certain provinces in Belgium and Spain.

Neighboring Austria on Thursday announced it would issue a travel warning for mainland Spain, becoming the latest country to do so amid a rise in new coronavirus cases in the fellow EU member.

Finland also introduced new controls on arrivals from some EU countries, including Belgium, the Netherlands and Andorra, putting a stop to tourists arriving from there and imposing a 14-day quarantine on other returnees.

"The situation is extremely delicate," the health ministry's strategic director Liisa-Maria Voipio-Pulkki said, adding that "some sort of second stage has begun."

Britain has reimposed quarantine for travelers from Belgium, Andorra and the Bahamas.

Norway announced Thursday that France would be considered a red zone due to the resurgence of coronavirus cases there, meaning all travellers arriving from France face a mandatory ten-day quarantine.

Switzerland, Monaco and the Czech Republic were also hit with similar restrictions, as well as two Swedish regions, the Norwegian foreign affairs ministry said.

"The infectious situation can change quickly, as can the restrictions," Foreign Minister Ine Eriksen Soreide said.

The United States bucked the trend despite its own soaring death toll, lifting a blanket warning against all foreign travel.

"Health and safety conditions (are) improving in some countries and potentially deteriorating in others," the State Department said in a statement.

Many nations are seeing new outbreaks, forcing local or citywide lockdowns and other quarantine measures.

Poland will re-impose compulsory face masks in all public spaces in nine districts amid a new high in infections.

The restrictions will come into force from Saturday and will also affect sports and cultural events in those areas, mainly in the south and east.

Greece's government on Wednesday announced a "wake-up week" on COVID-19, tightening restrictions after the steady rise in mostly domestic infections.

Officials have blamed the increase on overcrowding in clubs and social events.

The new virus outbreaks are forcing officials into an uncomfortable trade-off between public health and the need to bring economies back to life.
