Coronavirus: Hope in US as WHO hails global progress

The United States has logged a second consecutive day of fewer than 900 coronavirus deaths, as the World Health Organization hailed global progress but warned of the need for "extreme vigilance" against a second wave.

Optimism was tempered by the increasingly dire economic situation, with France showing a huge fall in activity last month and a warning that a major US airline would likely go under because of the pandemic, as jobs vanish and businesses go to the wall.

The virus has now killed more than 285,000 people, according to a tally compiled by AFP. The number of infections has surpassed 4.1 million.

Infection rates in many countries have started to slow, the World Health Organization (WHO) noted, with weeks of lockdown paying dividends.

"The good news is that there has been a great deal of success in slowing the virus and ultimately saving lives," WHO director-general Tedros Adhanom Ghebreyesus told a virtual briefing.

But the global health body warned of a second wave of transmission, with emergencies chief Michael Ryan lamenting that some governments were choosing to "drive through this blind" by not ramping up capacity to test and trace.

Swathes of the US have opened up in recent days, despite warnings that the virus is not fully under control in the world's worst-hit country.

There was some qualified good news for Americans on Monday, with a tally showing 830 deaths in 24 hours -- a second consecutive day of fewer than 900.

Nevertheless, more than 80,000 people are known to have died from the disease since it hit America's shores.

The true human cost could be much higher.

In a study, the US Centers for Disease Control and Prevention said the number of dead in worst-hit New York could be around 30 percent more than the official toll.

The virus appeared to have gained a foothold in the White House over the weekend, with a second confirmed case in the West Wing.

Staff there were told Monday they had to wear masks at work, and Donald Trump said he might limit contact with his deputy after an aide to Vice President Mike Pence tested positive.

Trump, who is desperately seeking to reboot the economy ahead of the November election, said the US was making "tremendous strides" in ramping up testing and the number of virus infections is "coming down very rapidly."

He said it was essential to get the country reopened.

"The people want our country open," the president said.

But Trump's top infectious diseases expert, Anthony Fauci, was set to warn the Senate Tuesday of "needless suffering and death" if that re-opening happens too quickly, according to the New York Times.

"We risk the danger of multiple outbreaks throughout the country. This will not only result in needless suffering and death, but would actually set us back on our quest to return to normal," he told the paper.

In California, which retains many of the restrictions dispensed with by other states, Tesla's outspoken boss Elon Musk said he would defy local rules and get his plant back in action.

"Tesla is restarting production today against Alameda County rules," Musk said in a tweet.

"I will be on the line with everyone else. If anyone is arrested, I ask that it only be me."

Musk's impatience -- reflected in anti- lockdown protests throughout the US -- comes as new figures showed the pain being felt all around the world.

On Tuesday, France reported a 27 percent plunge in economic activity for April compared with pre-pandemic forecasts.

Japanese auto giant Toyota said it expected a 79.5 percent drop in annual operating profit this fiscal year, calling the effect of the virus "wide-ranging, significant and serious."

Industry chiefs say the business landscape could look very different in the future.

"It's most likely," Boeing CEO David Calhoun told a reporter when asked if a major US airline could go bust over the coming months.

"You know something will happen in September," Calhoun said. "Traffic levels will not be back to 100 percent, they won't even be back to 25."

In Europe, where infection rates and death tolls have significantly tailed off, millions of people have begun emerging from lockdown.

Spaniards revelled in being able to visit outdoor terraces and cafes after months under one of the world's toughest lockdowns, although virus hotspots such as Madrid and Barcelona remain under wraps.

"It's very emotional, almost as if we were opening for the first time," said a smiling Raffa Olivier after setting up tables outside his ice-cream parlour in the seaside town of Tarragona.

Shopping strips were once again populated in Greece, while in other parts of Europe -- from the Netherlands to Switzerland and Croatia -- youngsters headed back to the classroom after weeks at home.

In Asia, normal life was also getting back on track with trains restarting in India later Tuesday.

Shanghai Disneyland reopened at the start of the week, and many workers returned to offices in Hong Kong.

There was also light at the end of the tunnel for sports fans.

Italian football's Serie A clubs are set to return to team training from May 18, and Germany's Bundesliga will kick off on Saturday -- but without fans.

"It's a good feeling. We are now looking forward to being able to resume playing," said Bayern chairman Karl-Heinz Rummenigge.

It is "an important and wonderful signal for the Bundesliga."
