Spain overtook China for the number of confirmed coronavirus cases reporting a total of 85,195 cases on Monday.
A new daily total of 812 deaths was a slight decrease on Sunday's record of 838, bringing the overall number of fatalities to 7,340.
Spain joins Italy and the US with over 85,000 infections.
At midday on Monday a minute's silence was held in a central Madrid square for the victims.
The news came as Spain put into effect tighter lockdown measures approved by the government. Announced over the weekend by Prime Minister Pedro Sanchez in the latest attempt to slow the spread of the coronavirus, they were approved at an extraordinary cabinet meeting on Sunday.
All non-essential workers are being confined to their homes from Monday until April 9, a further restriction on top of the constraints already imposed under the state of alarm declared on March 14.
Only people working in sectors assuring basic state functions such as health, security, energy, telecommunications, food and medical supplies can go out to work.
In Italy there was some encouraging news as the daily death toll -- at 756 on Sunday -- fell for the third day running.
"These are big changes, in order of 10-15% per day, and are reflecting the fact that the health system is answering back and of the efficacy of the measures taken," said pulmonologist and government adviser Luca Richeldi.
Meanwhile in the UK a health chief in England warned that it could be six months before life returns to normal.
Among the latest developments:
EasyJet says it is grounding its entire fleet of aircraft due to the pandemic, blaming "unprecedented restrictions". The budget airline will continue to make its planes available for rescue flights.
President Trump extended social distancing guidelines to April 30, having previously said he wanted the US to return to normal by Easter.
Spain's latest daily death toll of 812 on Monday followed a new one-day record the previous day. The total number of confirmed cases, which has now overtaken China's total, rose by eight percent in 24 hours.
Italy, which has the world’s highest number of deaths, counted 756 more deaths in 24 hours bringing its total death toll to 10,779. The figure was a significant drop on the two previous days' totals of 969 and 889.
Shoppers in Austria will have to wear face masks in supermarkets, Chancellor Sebastian Kurz announced. The masks will be handed out at shop entrances from Wednesday.
The Tokyo Olympic Games -- postponed by a decision taken last week by the International Olympic Committee and the Japanese government -- will take place from July 23 to August 8 next year, the IOC said. The Paralympics will take place from August 24 to September 5, 2021.
British Prime Minister Boris Johnson warned on Sunday that "things will get worse before they get better" and that further restrictions may be imposed on citizens.
In Russia, where the reported numbers had suggested the country was escaping the worst of the virus, the mayor of Moscow ordered a lockdown.
UK government says it will work to repatriate citizens
The UK foreign secretary Dominic Raab said the government was working to repatriate citizens stranded throughout the world amidst the crisis.
In a government briefing in which he stood in for Prime Minister Boris Johnson who has tested positive for the virus, Raab said the government was working with airlines to support charter flights for British citizens.
He said they would redesignate £75 million (€84 million) to bring down costs for British citizens.
There are more than 22,000 cases of the virus in the United Kingdom and more than 1,400 have died.
Watch the government's briefing on the virus in the video player below:
On Sunday UK Prime Minister Boris Johnson predicted that "things will get worse before they get better" and said more constraints on freedom of movement may be imposed.
The British leader, who is in self-isolation, stressed in a letter to be sent to every household in the country that confinement rules "must be observed" and that "police will issue fines" if they are broken.
His warning came just hours after the country announced that its death toll from the deadly virus had passed the grim 1,000 threshold.
And in the UK's daily briefing, the deputy chief medical officer Dr Jenny Harries said it could be at least six months before life returned to normal in the country, although she did add: "This is not to say we would be in complete lockdown for six months". It emerged that there will be a review of the situation every three weeks to see how things are progressing.
European lockdowns extended
Across Europe, countries have reinforced measures to contain the spread of the deadly disease with Hungary and Ireland both introducing 15-day lockdown on Friday.
France and Belgium, already nearly two weeks into their own lockdowns, both extended their self-isolation policies by another two weeks on Friday, a day after Spain had announced its own extension.
Russia announced on Saturday it would completely close its borders due to the global COVID-19 pandemic.
In the UK, NHS England announced on Saturday that two new hospitals would be created in the coming days.
These two facilities in Birmingham and Manchester — both to be housed in conference centres —will each provide an initial 500 beds that could then be expanded by up to 2,000 beds.
US leads world in COVID-19 cases
Meanwhile, the United States' top infectious disease scientist said on Sunday that the country could see more than 100,000 deaths and millions of coronavirus infections.
On Friday the US became the first country in the world to report more than 100,000 confirmed cases. It now counts over 125,000 cases.
The number of fatalities has also shot up, standing at 2,197 on Sunday with New York remaining the most heavily-impacted city.
New Yorkers and residents of neighbouring states including New Jersey and Connecticut are now being urged by the Centre for Disease Control "to refrain from non-essential domestic travel for 14 days".
Andrew Cuomo, the New York State governor, announced that the New York State primary for the US presidential election, planned for 28 April, would be postponed to 23 June due to the coronavirus pandemic.
More than 3.2 million Americans filed for unemployment benefits last week, according to the country's labour department, more than four times the previous record.
The US has responded to the growing number of coronavirus cases there with the largest economic rescue in history, worth €1.85 trillion, to help businesses, workers and the health care system.
The rescue package is larger than the 2008 bank bailout and 2009 recovery act.
A World Health Organization spokesperson said last week that the United States had the "potential" to become the new epicentre of the pandemic, due to a "very large acceleration" in infections.
'Fight only begun' in France
With 319 new deaths due to COVID-19 on Saturday, France's death toll crossed the 2,000 bar. Authorities also revealed that there are currently more than 4,200 people in intensive care in the country.
Prime Minister Edouard Philippe warned that "the first 15 days of April will be difficult, even more difficult than the 15 past ones", as France prepares for a sharp increase in the number of COVID-19 cases according to projections.
"The fight has only begun", Philippe said. The French health minister Olivier Véran added that the country wants to increase its intensive care bed capacity from 5,000 currently to 14,000.
The government issued measures to temporarily adapt the French labour law to create a "real war economy", the prime minister said with businesses allowed to make employees work longer hours, or work nights or Sundays as needed.
The measures include a €1 billion fund for small businesses and self-employed people, as well as financial aid for the travel sector, and systems put in place to pay salaries to the workers whose jobs have been stopped under the lockdown.
The government had previously announced that €45 billion had been mobilised to help struggling businesses and workers — by delaying or scrapping social benefits charges — and that it would also guarantee €300 billion in loans to struggling business and that social benefits charged would be delayed or scrapped.
Germany took a similar approach, promising that it would guarantee at least €550 billion in loans to businesses impacted by the pandemic and taking measures to alleviate the fiscal burden on companies.
Nations around the world are taking measures to mitigate the impact the pandemic will have on the economy. The Moody's credit rating agency forecast that all G20 countries would fall into recession this year.
At the European level, the European Central Bank has pledged to pour in €750 billion into the euro area economy while the European Commission has relaxed budgetary rules to give member states more leeway to allocate funds to the public health crisis.
It also announced on Saturday that it will issue a new budget proposal for the 2021-2027 period to include a "stimulus package that will guarantee the Union's cohesion through solidarity and responsibility," Commission President Ursula von der Leyen said.
Member states, however, have so far failed to find a common strategy, with hard-hit southern nations including Italy and Spain, calling for the creation of so-called "corona bonds" which would pool debt. They are opposed by richer northern member states including Germany and the Netherlands which favour using the European Stability Mechanism created following the 2008 financial crisis.
UN launches humanitarian response plan
The UN has launched a $2 billion (€1.85 billion) plan to develop a humanitarian response to COVID-19 in the poorest countries.
The plan was launched in tandem with the World Health Organization (WHO) and UNICEF to support vulnerable communities in the world.
The UN secretary-general appealed to governments to support the initiative financially.
"If we do not act decisively now, I fear that the virus will establish a foothold in the most fragile of countries, leaving the world more vulnerable as it continues to circle the planet," Antonio Guterres said.
"While COVID-19 is a threat to people everywhere, what's most worrying is the danger the virus poses to people already affected by crisis," said WHO director-general Dr Tedros Adhanom Ghebreyesus, talking about those displaced by conflict and climate or those living in poverty.
Meanwhile, UNICEF executive director Henrietta Fore spoke about how COVID-19 had upended the lives of children who cannot go to school.
"Children are the hidden victims of this pandemic," she said, pointing out that some children do not have basic hygiene services or access to online learning to continue their education.
A vaccine is still months away, says WHO
WHO chief Dr. Tedros Adhanom Ghebreyesus said on Friday that the world must "stay calm" and that "we must fight, unite, ignite".
"Unite because we are one humanity, we can only fight together. And ignite the industrial mind and innovation of G20 countries to produce and distribute the tools needed to save lives."
He said that a COVID-19 vaccine is "still 12 to 18 months away".
The disease has so far predominantly impacted older adults and people of any age who have a serious underlying medical condition such as chronic lung disease, a serious heart condition, obesity or patients fighting cancer.
But the young are not immune. A healthy 16-year-old girl died of coronavirus in France on Thursday.
Drastic action around the world
Hotels in Spain have been converted into makeshift hospitals and an ice rink in the capital Madrid is being used as a morgue, as the infections and deaths continue to shoot up.
In Italy, authorities are investigating if a hotly contested Champions League match in Milan in February poured rocket fuel on the crisis that is overwhelming Italian hospitals. Italian doctors are being forced to choose who will receive desperately needed ventilators and who won't.
Both these countries, and others in Europe, are seeing their health care systems come under intense strain, with hospitals running short of critical equipment needed to treat patients and keep doctors and nurses safe. Doctors are dying in Italy and Spain says 14% of its infections are health care workers.
Finland, which has 1,025 confirmed cases of coronavirus and has reported seven deaths, announced on Wednesday the lockdown of the capital Helsinki and its region, starting Friday until 19 April.
Russia grounds flights, delays constitutional changes
Russia announced on Saturday that it would temporarily close all its borders starting on March 30. International flights had already been grounded from Friday except those bringing Russian nationals home from abroad.
Russia also delayed a vote on constitutional changes amidst the coronavirus outbreak. The vote included a change to allow President Vladimir Putin to seek another presidential term.
The country has more than 1,260 confirmed cases, according to the John Hopkins University's tally, and has so far recorded four deaths.
New Zealand records first death
Case numbers in countries with fragile health care systems are rising, and governments are taking drastic action to avoid the sort of crises currently being experienced in western European countries and the United States.
Virus cases in South Africa rose to 709 as the country got ready to go on lockdown on Friday. New Zealand declared an emergency ahead of an unprecedented lockdown which begins on Wednesday. The island nation's recorded its first death on Sunday.
And India announced a 21-day total lockdown in the country of 1.3 billion people - the most sweeping effort yet to stop the transmission of COVID-19.
"To save India and every Indian, there will be a total ban on venturing out of your homes,” Prime Minister Narendra Modi said.
There were 981 cases of the virus in the country on Sunday, according to a tally maintained by researchers at Johns Hopkins University.
