The world began ushering in 2022 on Friday after another tumultuous and pandemic-ridden year capped by new restrictions, soaring case numbers, and a slight glimmer of hope for better times ahead.
The past 12 months saw a new US president and a fresh Adele album, the first spectator-free Olympics, and dreams of democracy from Afghanistan to Sudan and Hong Kong crushed by authoritarian regimes.
But it was the pandemic — now entering its third year — that again dominated life for most of humankind.
More than 5.4 million people have died since the coronavirus was first reported in central China in December 2019.
Countless more have been sickened, subjected to outbreaks, lockdowns, lock-ins and an alphabet spaghetti of PCR, LFT and RAT tests.
The year 2021 started with hope, as life-saving vaccines were rolled out to around 60 percent of the world's population, although many of its poor still have limited access and some of its rich falsely believe the jabs are part of some ill-defined plot.
As the year drew to a close, the emergence of the omicron variant pushed the number of daily new COVID-19 cases past one million for the first time, according to an AFP tally.
France on Friday became the latest country to announce omicron was now its dominant coronavirus strain.
In Britain, the United States, and even Australia — long a refuge from the pandemic — the variant's prominence is driving record new cases.
- To party, or not? -
From Seoul to San Francisco, celebrations were again cancelled or curtailed in the face of the surge in infections.
The glitzy Gulf city state of Dubai went ahead with its celebrations despite the surge in infections, with 36 firework displays at 29 locations.
Revelers gathered from early evening to watch the spectacle at the world's tallest tower, the Burj Khalifa.
At Expo 2020, the world fair which opened a year late because of COVID, celebrations started in the afternoon and were scheduled to continue into New Year's Day.
Authorities warned they would fine anyone not wearing a protective mask.
In Sydney, which in normal times bills itself as the "New Year's Eve capital of the world", the vast harbor where people gathered to watch the city's fireworks was notably uncrowded.
With tourists still unable to enter the country and many residents fearful of the rapid spread of omicron, tens of thousands were estimated to have attended, rather than the 1 million-plus who normally flock to the foreshore.
Still, the city saw New Year's Eve in with a bang, igniting 6 tonnes of technicolored fireworks that lit up the Opera House and floating barges, turning the Harbour Bridge rainbow-like.
"I'm just trying to focus on the positive things that happened this year, rather than dwelling on all the bad things that have happened," 22-year-old medical student Melinda Howard told AFP as she waited for the show.
In Sudan, Christian figures announced the cancellation of New Year's celebrations in memory of 5 pro-democracy demonstrators killed on Thursday in the latest protests against an October coup.
In Tunis, authorities cited the "rise in cases" of coronavirus for the last-minute cancellation of festivities planned for Bourguiba Avenue, the capital's central thoroughfare.
In contrast, South Africa — the first country to report omicron back in November — lifted a curfew late Thursday to allow festivities to go ahead.
Health officials said that a dip in infections in the past week indicated the peak of the current wave had passed — crucially without a significant increase in deaths.
- 'Only one desire' -
In Rio, celebrations on Copacabana Beach will go ahead in a scaled back format — though crowds of revelers are still expected at the traditional party spot.
"People have only one desire, to leave their homes, to celebrate life," 45-year-old Copacabana beach waiter Francisco Rodrigues said.
In India, Delhi implemented a 10 p.m. curfew while Mumbai police issued evening bans on people visiting the city's beaches and seafront promenades, normally popular sites for seeing in the new year.
The UK also marks the New Year in muted fashion, and does so under the warmest temperatures on record, near 15 degrees Celsius.
In the Netherlands, authorities banned fireworks for a second year in a row in an effort to prevent firework-related injuries putting additional strain on health services stretched by COVID.
But a 12-year-old child was killed and another seriously injured while apparently watching an adult set off fireworks, police said.
- Trying times -
The World Health Organization has warned of trying times ahead, saying omicron could lead to "a tsunami of cases".
Many Western leaders have been hesitant to reimpose strict controls seen in 2020, for fear of sparking a new economic downturn.
But on-again-off-again restrictions have still prompted frequent, vocal and occasionally violent anti-lockdown, anti-vaccine and anti-government protests.
Experts and non-experts alike hope that 2022 may be remembered as a new, less deadly phase of the pandemic.
"Hopefully 2022 is going to be better for everyone," said 31-year-old reveler Oscar Ramirez in Sydney.
"Everyone in the world needs a big change."
