Brazil and Mexico reported record daily coronavirus death tolls as governments in Latin America battled to fortify defences against the accelerating pandemic with fresh lockdown orders and curfews.
European nations are emerging from months of lockdowns with some borders reopening, but South and Central America have become the new hotspots in a crisis that has claimed at least 385,000 lives worldwide.
Mexico announced more than 1,000 coronavirus deaths in a day for the first time, while Brazil reported a record 1,349 daily deaths.
Brazilian President Jair Bolsonaro has staunchly opposed lockdowns but many local authorities have defied him and, with the crisis deepening, a vast section of Bahia state was placed under curfew yesterday.
There was more cause for concern in Chile, where the government said it was extending a three-week shutdown of the capital Santiago after a new record for daily deaths.
And in more evidence of the scale of the crisis in Latin America, the journalists' union in Peru said at least 20 reporters had died from the coronavirus.
The outbreak in Peru has been so intense that oxygen tanks needed in hospitals have become scarce, with many lining up to buy them for their loved ones.
"We haven't found oxygen yet," said the daughter of a woman with Covid-19 in Lima.
"I'm worried about my mom more than anything else, because she's going to need a lot of oxygen and the hospital doesn't have enough."
Experts have warned that travel restrictions will be needed around the world in some form until a vaccine is found and efforts to develop one are gathering pace.
Britain to host global vaccine summit
Britain is set to host a major meeting today, with more than 50 countries as well as individuals such as Bill Gates taking part, to raise money for Gavi, the global vaccine alliance.
Gavi and its partners will also launch a financing drive to purchase potential Covid-19 vaccines, scale-up their production and support delivery to developing nations.
Tests on one potential vaccine, being developed by Oxford University, will begin on 2,000 health services volunteers in Brazil next week.
But months of lockdowns that left half of humanity under some form of confinement have battered the global economy, and there is desperation in many countries to reopen and revive businesses.
Italy opened its borders to European travellers yesterday, hoping tourism will revive its recession-hit economy three months after its shutdown, though a full recovery seemed a long way off.
"I don't think we'll see any foreign tourists really until the end of August or even September," said Mimmo Burgio, a cafe owner near Rome's Colosseum. "Who's going to come?"
The United States remains the hardest-hit nation in the world, with 1.85 million infections and more than 107,000 deaths, and there are fears that the ongoing wave of protests in the country over racism and police brutality could fuel the spread of the virus.
Massive rallies have been held around the US in protest at the death of African-American man George Floyd in Minneapolis on 25 May, despite the risk of Covid-19 and restrictions on public gatherings.
Many have said that while they were aware of the risk of infection, the issue of police brutality and racism was so widespread and long-standing that they had to come out.
Cav Manning from New York, was among the tens of thousands across the US willing to risk infection as he joined a protest in Brooklyn earlier this week.
"What we saw is so disturbing that we've got to be out here right now," he told AFP.
"Despite Covid, despite the fact that you might get infected."
