Coronavirus deaths soared across Europe and the United States on Sunday despite heightened restrictions, as Germany banned gatherings of more than two people and Chancellor Angela Merkel went into quarantine.
In the US, President Donald Trump ordered emergency medical stations for hotspots, hospitals scrambled to find ventilators, and a trillion-dollar proposal to rescue America's reeling economy crashed to defeat.
Germany and Greece became the latest countries to tighten curtailments on movement as the virus kept nearly a billion people indoors and intensified fears of a global recession unlike any experienced for decades.

The epicentre is firmly in Europe after shifting from China where the illness first emerged late last year.
"I'm a little upset with China. I'll be honest with you...," Trump said referring to a lack of cooperation and information early on in the crisis.
Italy's world-topping toll from the pandemic approached 5,500 as the Mediterranean country reported another 651 deaths, a day after it overtook China for the highest number of fatalities.
Greece imposed a national lockdown and in Germany Merkel began quarantining at home after being treated by a doctor who has since tested positive for the virus.
But lockdown measures in Italy have done little to stem the outbreak and New Yorkers were finding it difficult on a spring weekend to put a stop to fun in the city that never sleeps.
"I don't know what they're not understanding," said Governor Andrew Cuomo, complaining that parks were still full of people not respecting social-distancing orders.

Residents across France, where the death toll jumped to 562, remained shut in their homes. A curfew was imposed in some regions and the mayor of Paris called for even more drastic confinement measures in a city under lockdown.
Britain inched toward similar measures as Prime Minister Boris Johnson warned the country was a couple of weeks behind registering similar numbers to Italy.
US SENATOR POSITIVE
In the US, where Rand Paul became the first US senator to test positive, a Republican-proposed bill earmarking up to $2 trillion in funding for American families, businesses and hospitals, failed to pass after receiving zero support from Democrats who said it wasn't enough.
Several European countries have already announced their own stimulus packages to stave off economic collapse.

While the number of cases in China – which reported its first local infection in four days on Sunday – has slumped dramatically since the crisis began, there are fears in Asia of "imported" cases from other hotspots like Europe.

Normally bustling streets in New Delhi and Mumbai were mostly deserted and many shops shuttered during India's one-day nationwide "self-imposed curfew."

In sport, International Olympic Committee president Thomas Bach said postponing the 2020 Games was an option but that cancellation was "not on the agenda."
Accurate Covid-19 figures are difficult to obtain because many of the victims suffered from other illnesses, and infection rates are uncertain because of a lack of testing in many countries.
