India's coronavirus disaster deepened on Thursday with the daily death toll climbing above 3,600 as dozens of countries sent urgent medical aid to help tackle the spiraling crisis.
India remains in the spotlight although the pandemic is still worsening in many other parts of the world.
However the United States and several European nations are starting to ease restrictions as their vaccination campaigns pick up.
In New York, Mayor Bill de Blasio said the city hopes to "fully reopen" on July 1.
And in France, cafes, cultural venues and business will reopen in several phases from next month, President Emmanuel Macron said.
Irish Prime Minister Micheal Martin announced plans to lift lockdown restrictions starting May 10, including "vaccine bonus" perks for those who have had both jabs.
"Hope is returning," Martin said.
Portugal said it would reopen its land border with Spain on Saturday.
But the World Health Organization issued a stark warning to European nations that relaxing COVID measures could spark a "perfect storm" allowing cases to spiral -- as in India.
"It is very important to realise that the situation in India can happen anywhere," said WHO Europe chief Hans Kluge.
India deaths rising exponentially
Death and infection rates have been rising exponentially throughout April in India, which experts blame in part on mass gatherings.
On Thursday, the south Asian nation reported 3,645 deaths over the past 24 hours, while confirmed new cases hit a new global record with more than 379,000. The official numbers are widely believed to be far below the reality.
The pandemic has claimed at least 3.1 million lives around the world, with India accounting for more than 200,000 fatalities, the worst toll outside the Americas.
The US is the worst-affected country with over 570,000 deaths, followed by Brazil and Mexico.
In many Indian cities, hospitals are running out of beds as relatives of the sick crowd jostle for medicines and oxygen cylinders.
"We rushed to multiple hospitals, but were denied admission everywhere," said the son of an 84-year-old woman who died at home this week after a desperate search for a hospital bed and oxygen in Kolkata, capital of West Bengal state.
The Indian government will open vaccinations to all adults from Saturday. It had previously limited shots to the over-45s and certain other groups.
Several states have warned, however, they do not have sufficient vaccine stocks and the expanded rollout is threatened by administrative bickering, confusion over prices and technical glitches on the government's digital vaccine platform.
'Unprecedented situation'
More than 40 countries have committed to sending India vital medical aid, particularly oxygen amid a severe shortage, Foreign Secretary Harsh Vardhan Shringla said.
The supplies include almost 550 oxygen-generating plants, more than 4,000 oxygen concentrators, 10,000 oxygen cylinders as well as 17 cryogenic tankers.
Hundreds of thousands of doses of COVID-19 treatment drugs as well as raw materials to produce vaccines were also being sent.
The WHO has said the virus variant feared to be contributing to the catastrophe on the sub-continent has now been found in more than a dozen countries.
But the body has stopped short of saying it is more transmissible, more deadly or able to dodge vaccines.
Lollipop tests
In the United States, President Joe Biden on Wednesday hailed his nation's inoculation program as one of "the greatest logistical achievements" in American history.
More than 234 million doses had been administered by Wednesday in the United States, according to the Centers for Disease Control.
Countries are looking to do the same in Europe, and Germany hit a new record in daily vaccinations with 1.1 million people, Health Minister Jens Spahn said.
That meant Europe's biggest economy for the first time vaccinated more than one percent of its population in 24 hours.
The EU also inched further toward a COVID certificate for travel, after the EU parliament approved the position it would take in talks with the executive branch and the bloc's members.
In France, where the rollout has stuttered, President Macron set out a timetable for a gradual lifting of COVID curbs from May 19 to the end of June.
Shortly after he made his comments, the first case of the Indian variant of coronavirus was detected in mainland France.
Amid concern that virus variants may spread quickly among youngsters, a lollipop-shaped test is being rolled out in some Austrian kindergartens.
Burgenland province said it had already ordered 35,000 lollipop tests after a succesful pilot scheme.
"Put the test in the mouth, suck for 90 seconds, dip the test in the container, wait 15 minutes, check the result," the instructions read.
