The world ushered in 2022 on Friday with scaled-back celebrations due to new restrictions aimed at slowing soaring Covid cases -- although hope remained for a better new year.
New York revived its New Year's Eve ball drop in Times Square in limited form, Paris nixed its fireworks show over rising Omicron cases and London's pyrotechnic display was broadcast on TV.
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 Myanmar 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?
Parts of the Pacific nation of Kiribati became the first to welcome in the new year from 1000 GMT.
But from Seoul to San Francisco, celebrations have again been cancelled or curtailed as infections rise.
In Sydney, which in normal times bills itself as the "New Year's Eve capital of the world", the vast harbour 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 one million-plus who normally flock to the foreshore.
Still, the city saw New Year's Eve in with a bang -- igniting six tonnes of technicoloured 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.
Dubai went ahead with its celebrations undeterred, with 36 firework displays at 29 locations.
Elsewhere in the Middle East, municipal authorities in the Tunisian capital Tunis cited the "rise in cases" of coronavirus for the last-minute cancellation of a concert and other festivities planned for Bourguiba Avenue, the main city-centre 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.
A new-year tragedy struck in India, where at least 12 people died and 13 were injured in a stampede at a religious shrine during Saturday's early hours. Pilgrims had gathered to offer new-year prayers, officials said.
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 went ahead in a scaled-back format, although crowds still arrived 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.
Authorities in Seoul are showing caution, barring spectators from a traditional midnight bell-ringing that will instead be live-streamed.
In India, fearing a repeat of a devastating virus surge that overwhelmed the country in April and May, cities and states have imposed restrictions on gatherings. Delhi implemented a 10:00 pm curfew.
Mumbai police on Friday issued evening bans on people visiting public places such as the city's beaches and seafront promenades, normally popular sites for seeing in the new year -- with the restrictions set to last two weeks.
The UK also marks the new year in muted fashion, but at least does so under the warmest temperatures on record, near 15 degrees Celsius (59 degrees Fahrenheit).
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 reveller Oscar Ramirez in Sydney.
"Everyone in the world needs a big change."
