China's leaders staged a triumphant ceremony to celebrate beating the coronavirus on Tuesday as billions of people around the world still suffer the fallout from the pandemic and the global death toll nears 900,000.

The upbeat mood in Beijing comes as concerns grow about a resurgence of COVID-19 across Europe, with France tightening restrictions, cases in Britain spiking and schools resuming around the region.

Tour de France director Christian Prudhomme has tested positive for COVID-19, prompting French Prime Minister Jean Castex to take a test, officials said, after the pair shared the same car to follow a stage of the cycling's premier sporting event at the weekend.

Worldwide infections to date now stand at more than 27 million and over 890,000 people have died from the disease, with the pandemic showing no sign of peaking.

But in China the virus has been all but banished through lockdowns and travel restrictions earlier in the year that have officials touting the nation as a coronavirus success story.

President Xi Jinping said China had passed "an extraordinary and historic test" during an awards ceremony for medical professionals decorated with bugle calls and applause.

"We quickly achieved initial success in the people's war against the coronavirus," Xi said.

"We are leading the world in economic recovery and in the fight against COVID-19."

The nation’s propaganda machine has been attempting to seize the narrative surrounding the pandemic, reframing the episode as an example of the agility and organisation of the Communist leadership.

Beijing is also touting progress on its vaccines as a sign of global leadership and resilience.

China put its homegrown COVID-19 vaccines on display for the first time at a Beijing trade fair this week and authorities hope the jabs will be approved for use by year-end.

The vaccines are among nearly 10 worldwide to enter phase 3 trials, typically the last step ahead of regulatory approval, as countries race to stub out an illness that continues to ravage large parts of the globe.

Spain has become the first country in Western Europe to pass half a million infections. The nation had largely gained control over its outbreak but cases have surged since restrictions were removed at the end of June.

In Morocco, the government shut all schools and imposed a lockdown on Casablanca on the day classes were supposed to resume after cases surged in the city.

Officials said the virus risked overwhelming the North African country if it was not controlled, but some parents were left fuming.

"They were on cloud nine over returning to school tomorrow,” one father wrote of his children on Twitter.

Restrictions have also been reimposed in France where seven more regions were placed on a red list after recording daily infection rates of between 7,000 and 9,000.

In England, officials fiddled with quarantine rules again, imposing curbs on travellers from seven Greek islands popular with holiday makers, after Britain at the weekend registered a level of infection not seen since late May.

In Asia, India pressed ahead with reopening its battered economy despite surpassing Brazil on Monday as the second-most infected nation in the world with 4.2 million cases.

The country’s top tourist attraction the Taj Mahal will reopen on September 21, officials said, more than six months after it was shut.

Trains began running again in the capital New Delhi after a five-month shutdown and 12 other cities also restarted subway services.

"For our lives to move on, we have to get out of our homes... so this is a good move by the government,” commuter Deepak Kumar told AFP in Delhi.

South Africa, however, reported Tuesday its economy shrank by more than half in the second quarter, an unprecedented decline, as the pandemic took its toll on Africa’s most industrialised state.

Barty to skip French Open 

French footballer Kylian Mbappe became the latest sports star to test positive for the virus after his club teammate Brazilian forward Neymar was confirmed to have COVID-19 last week.

Mbappe has been ruled out of France’s Nations League game against Croatia on Tuesday and is the seventh Paris Saint-Germain player to contract the illness.

A number of tennis players have also been infected, and on Tuesday, world number one Ashleigh Barty announced she will not defend her French Open crown due to virus fears.

The Australian star said it was a "difficult” decision but the health of her family and team came first.
