The worldwide death toll from the coronavirus hit 100,000 as Christians around the globe marked a Good Friday unlike any other in front of computer screens instead of in church pews and some countries tiptoed toward reopening segments of their battered economies.

Around the world, public health officials and religious leaders alike warned people against violating the lockdowns and social distancing rules over Easter and allowing the virus to come storming back.

Authorities resorted to roadblocks and other means to discourage travel.

In Italy, officials employed helicopters, drones and stepped up police checks to make sure residents didn't slip out of their homes. On Thursday alone, police stopped some 300,000 people around Italy to check whether they had permission to travel. About 10,000 were issued summonses.

Some churches held services online, while others arranged prayers at drive-in theatres.

Fire-scarred Notre Dame Cathedral came back to life briefly in Paris, days before the first anniversary of the April 15 inferno that ravaged it. Services were broadcast from the closed-to-the-public cathedral.

The holiday observances came as the worldwide number of deaths tracked by Johns Hopkins University hit a bleak milestone of 100,000 since late December, when the outbreak emerged in China. The number confirmed to be infected was more than 1.6 million.

The true number of lives lost is believed be much higher because of limited testing, different rules for counting the dead and cover-ups by some governments. For example, in places like New York, Italy and Spain, many victims who died outside a hospital say, in a home or a nursing home, have not been part of the count.

In the US, deaths climbed past 16,700, with close to half in New York state. Still, there were signs of hope. New York state reported 777 new deaths, down slightly from the day before, for an overall toll of more than 7,800.

"I understand intellectually why it's happening," Gov. Andrew Cuomo said. "It doesn't make it any easier to accept."

But state officials said the number of people in intensive care dropped for the first time since mid-March and hospitalisations are slowing: 290 new patients in a single day, compared with daily increases of more than 1,000 last week.

Cuomo said if the trend holds, New York might not need the overflow field hospitals that officials have been scrambling to construct.

"There is a light at the end of the tunnel," said Dr Jolion McGreevy, medical director of Mount Sinai Hospitals emergency department. "Its getting better, but it's not like it's going to just drop off overnight. I think it's going to continue to slowly decline over the next weeks and months."

Struggling economies

With the pandemic slamming economies, the head of the International Monetary Fund warned that the global economy is headed for the worst recession since the Depression.

In Europe, the 19 countries that use the euro currency overcame weeks of bitter divisions to agree on spending $550 billion to cushion the recession caused by the virus.

Mario Centeno, who heads the eurozone finance ministers group, called the package "totally unprecedented. ... Tonight Europe has shown it can deliver when the will is there."

As weeks of lockdowns were extended in nation after nation, governments were pressed to ease restrictions on key businesses and industries.

After a two-week freeze on all non-essential economic activity, Spain decided to allow factories and construction sites to resume work on Monday, while schools, most shops and offices will remain closed.

Spanish authorities said they trust that the move wont cause a significant surge in infections.

"We wouldn't be adopting them otherwise," said Mara Jos Sierra of Spain's health emergency centre.

The head of the World Health Organization, Tedros Adhanom Ghebreyesus, warned that a premature lifting of restrictions could lead to a deadly resurgence.

In Italy, the industrial lobbies in regions representing 45 per cent of the country's economic output urged the government to ease its two-week lockdown on all non-essential manufacturing, saying the country “risks definitively shutting down its own motor, and every day that passes the risk grows not to be able to restart it."

Around the world

Italy reported 570 additional deaths for a running total of more than 18,800 — the highest of any country but said the number of hospital admissions is falling along with the number of patients in intensive care.

Malaysia's prime minister announced a two-week extension to the country's lockdown but said selected economic sectors can reopen in phases while following strict hygiene rules.

In the Kenyan capital of Nairobi, people desperate for food stampeded, pushing through a gate at a district office in the Kibera slum. Police fired tear gas, injuring several people.

In Japan, the worlds third-largest economy, many have criticised Prime Minister Shinzo Abe as being too slow to act against the pandemic. In a rare rebuke, the Japanese prefecture of Aichi, home to the Toyota car company, declared its own state of emergency, saying it cannot wait for the government.

"The situation is critical," said Aichi Gov. Hideaki Omura. "We decided to do everything we can to protect Aichi residents lives and health."

Japan has the world's oldest population, and Covid-19 can be especially serious for the elderly.

In some of the worst-hit countries, Italy and Spain, new infections, hospitalisations and deaths have been levelling off. But the daily tolls remain shocking.

The 605 new deaths announced in Spain were the lowest in more than two weeks. The coronavirus has claimed more than 15,800 lives there, though the rates of contagion and deaths are dropping.

Britain recorded 980 new deaths, its highest daily total, for close to 9,000 in all.

British Prime Minister Boris Johnson was moved out of intensive care on Thursday after spending three nights there being treated for the virus. The 55-year-old remained hospitalised in London.

His father, Stanley Johnson, said the prime minister needs to rest up before returning to work.
