The speed with which new variants of the COVID-19 virus spread around the world can leave government’s scrambling to catch up. What is sometimes more remarkable is the speed with which those new variants are detected.
It has taken barely two weeks from the initial testing of ‘patient zero’, before potentially the entire globe is readying itself to examine COVID test samples to see if they contain the Omicron variant.
Patient zero, called n=1 or the index case by the scientific community, arrived at Hong Kong International Airport on 11 November, having flown in from South Africa via Doha in Qatar, on flight QR818.
He had been in South Africa for almost three weeks, and had tested negative the day before he began his trip there.
On his return to the territory on the Qatar Airways flight, the 36-year-old was in seat 31A, and was showing no symptoms when he checked into the Regal Airport Hotel in Chek Lap Kok, to begin his mandatory quarantine. He also tested negative on his return.

Hong Kong has some of the most stringent regulations on arrival in the world.
Anyone coming from a “high-risk” country can only board flights for the territory if they are fully-vaccinated Hong Kong residents and even then they have to undergo compulsory isolation for 21 days in a designated quarantine hotel when they arrive.

While in quarantine, they must undergo six COVID tests and then they must monitor themselves for the following seven days, after which they are tested again 26 days after the day of their arrival.
The man in question had fulfilled all the requirements, having received the Pfizer vaccine on 13 May and 4 June, and outwardly there were no signs his case was anything unusual.

But two days into his quarantine, he was tested again, on 13 November, and after showing a high viral load was sent to hospital the next day.
Meanwhile, another passenger that had arrived in Hong Kong the day before the man who later became patient zero, was staying in a room opposite him on the fifth floor of the same quarantine hotel.
He tested negative twice before, on 18 November, a result showed he too had a high viral load and he was also rushed to hospital.
Like all arrivals who test positive after coming to Hong Kong, they were give case numbers – 12388 and 12404.
Early conclusions from Hong Kong’s health authorities were that case 12404 might have been infected with the variant as air flowed into the corridor when case 12388 opened his hotel room door as he was not wearing a surgical mask.

While the test results from the Hong Kong travellers were being analysed, other researchers in South Africa and Botswana were also looking into a newly emerging variant.
Just three days after the Hong Kong traveller went to his quarantine hotel, a number of people were being routinely tested in the South African province of Gauteng.
At around the same time, South Africa, and particularly Gauteng, began to see a sudden uptick in cases.
South African scientists began to come to the conclusion they were seeing something new after detecting a group of related SARS-CoV-2 viruses that were turning up in large numbers, compared to other variants.

What is the new COVID variant?
Out of the specimens collected between 14 and 23 November, more than 70% were of the same type.
They raised the alarm on 22 November.
The next day the new variant was picked up by GISAID, the open-access database of flu viruses and coronavirus variants that has been critical to spreading news around the world about emerging forms of COVID-19.
On 24 November, it was given a new name under the criteria given to emerging COVID variants – B.1.1.529.

Scotland and Wales are calling for all UK travellers to isolate for eight days when arriving in the country.
On the same day, the new variant was reported to the World Health Organisation, which convened its technical advisory group – similar to WHO’s equivalent to SAGE – to assess what should be done.
The UK, responding to the rapidly evolving situation, designated the virus type a variant under investigation, VUI-21NOV-01, on 25 November.
As it did so, cases in South Africa were shooting up.
Professor Sharon Peacock of COG-UK Genomics UK Consortium, which oversees sequencing in the UK, said on Friday: “The number of recorded COVID-19 infections on 16 November 2021 was 273 cases. By 25 November this had risen to more than 1,200 cases.

Health minister Edward Argar says Omicron cases will rise across the UK in the run-up to Christmas.
“More than 80% of these were from Gauteng province. Cases in Gauteng province initially appeared to be clustered, but over time there has been more widespread dispersal of infections across the province.
“An analysis of the R value (a measure of growth rate) is 1.47 for South Africa as a whole, but initial estimates for Gauteng province are 1.93. Based on this measurement, it indicates that growth rate of cases is considerably higher in Gauteng province than the rest of the country.
“Around 100 B.1.1.529 genomes have now been identified in South Africa, mostly from Gauteng province. But this region is also where the sequencing has been targeted, and the question is whether the variant is present over a wider geographic area.”

South Africa’s president says Omicron is now responsible for the majority of cases in the country’s most populated area.
In total, according to the European Centre for Disease Control, South African investigators examined 77 samples in Gauteng taken between 12 and 20 November looking for a specific mutation that suggested Omicron was present, and found it in all cases.
The results, say the ECDC, suggest that Omicron is already dominant in Gauteng and is present in significant proportions in most parts of South Africa.
The question is, what does this mean for the rest of the world?
It is clear that Omicron has been in the UK for several days.
After one of the first cases in England was revealed to have been identified in Brentwood, Essex County Council said staff, customers and delivery workers who visited a branch of KFC on Brentwood High Street on Friday 19 November, between 1pm and 5pm, should take a PCR test immediately – suggesting a person with the variant was in the restaurant at the time.

Sky’s Charlotte Lomas looks at what scientists know so far about the Omicron COVID variant and how it behaves.
Likewise, they asked anyone in the congregation of the town’s Trinity Church on Sunday 21 November to do the same.
Essex’s director of public health Dr Mike Gogarty told the BBC’s World At One programme that the person in question was tested on 20 November and has contracted the variant from someone who had been in contact with someone who had been to South Africa – in a clear case of community transmission.
He said: “We are talking probably about two weeks from now since that person returned from Africa.”
Both the UK cases identified on Saturday, which also included one in Nottingham, were linked to travel in South Africa. A third case in the London borough of Westminster, who had previously been in southern Africa, has since left the country.
But while South Africa, like the UK, has an effective system to sequence COVID test samples, many other countries in Africa do not.
Omicron has been detected early in Botswana, but there are concerns it may be widespread in several other nations in southern Africa.
Some 98 samples were sequenced in Botswana to allow the identification of six cases of Omicron by Friday, reported the ECDC, but in the same period countries like Kenya sequenced just five cases, with no Omicron cases.

Dr Chaand Nagpaul says there needs to be a consistent policy in mask wearing in public.
Israel, one of the world’s most vaccinated countries, said on Friday it had also detected the country’s first case of Omicron in a traveller who had returned from Malawi. Two other suspected cases were also placed in isolation.
On that day, as the world became aware of the extent of the spread, markets reacted with oil prices plunging and airlines shares suffering major losses.
A case was also confirmed in Belgium and on Saturday suspected cases were reported in Germany, Italy and the Czech Republic.

Denmark and Australia announced two cases and the Netherlands identified 13 Omicron cases in dozens of COVID-positive travellers from South Africa on Sunday.
On Monday, further cases were announced in Portugal, where 13 players and staff members of Lisbon soccer team Belenenses were found to be positive for the variant even though only one player had been recently to South Africa.
Countries across the planet have reacted by closing their borders or reintroducing severe travel restrictions.
While scientists have raised the alarm, and have said they expected it to spread, many say there is no more cause for concern in terms of the impact on people, than there might have been if the Delta variant stays dominant.

Reacting to the news cases had been discovered in Scotland, Professor Rowland Kao, the Sir Timothy O’Shea Professor of Veterinary Epidemiology and Data Science at the University of Edinburgh, said: “It is now clear that the Omicron variant has been spreading around the world for some days, if not weeks prior to the alarms being raised, and this is only to be expected for a virus which transmits as easily as SARS-CoV-2, and with international travel now substantial (even though not quite at the level pre-pandemic).
“Evidence of community spread in two locations in Scotland (ie cases with no obvious risks other than community spread) and no obvious source yet, are strong indicators that we shall see more cases in Scotland arise over the next few days and weeks.
“As always, anything individuals can do to mitigate spread (physical distancing, taking lateral flow tests when appropriate and being aware of COVID symptoms and testing) will be beneficial.
“However it is important to remember that the omicron variant may not pose an increased health risk – it may in fact cause milder infections. However we shall only know for sure in the next few weeks.”

From being able to count on one hand the number of warships and boats in the Caribbean, since August we can see the build-up of the number, and variety of ships under US command.
And that’s only at sea – air power has also been deployed, with bombers flying over the Caribbean, and even along the Venezuelan coast, as recently as this week.

Sky’s Data & Forensics unit has verified that in the past four months since strikes began, 23 boats have been targeted in 22 strikes, killing 87 people.

It was the first such strike since 15 November and since the defence secretary, sometimes referred to as secretary of war, Pete Hegseth, came under scrutiny for an alleged “second strike” in an earlier attack.
The US says it carried out the action because of drugs – and there has been some evidence to support its assertion.
The Dominican Republic said it had recovered the contents of one boat hit by a strike – a huge haul of cocaine.
Legal issues
Whatever the cargo, though, there are serious, disputed legal issues.
Firstly, it is contested whether by designating the people on the boats as narcoterrorists, it makes them lawful military targets – or whether the strikes are in fact extra judicial murders of civilians at sea.
And more specifically… well, let’s go back to that very first video, of the very first strike.
What this footage doesn’t show is what came afterwards – an alleged “second strike” that targeted people in the water posing no apparent threat.
And the 4 December strike shows this strategy isn’t over.
The strikes are just part of the story, as warships and planes have headed toward the region in huge numbers.
Drugs or oil?
Some have said this isn’t about drugs at all, but oil.
Venezuela has lots – the world’s largest proven reserves.
Speaking to the faithful on Fox News, Republican congresswoman – and Trump supporter – Maria Salazar said access to Venezuela would be a “field day” for American oil companies.
And Maduro himself has taken up that theme. A few days later, he wrote this letter to OPEC – which represents major oil producing nations – to “address the growing and illegal threats made by the government of the United States against Venezuela”.
That’s how Maduro has framed this – a plan by the US “to seize Venezuela’s vast oil reserves… through lethal military force”.
Lethal military force – an understatement when you think of the armada lying in wait.
And it may be called upon soon. Trump on Tuesday said he’s preparing to take these strikes from international waters on to Venezuelan territory.
Maduro has complained of 22 weeks of “aggression”. There may be many more to come.

Donald Trump’s bruising assessment of Europe as “weak” and “decaying” is a bitter blow to nations already reeling from the release of his national security strategy.
At the end of the 45-minute interview with Politico, EU leaders might be forgiven for thinking, with friends like these, who needs enemies?
“Europe doesn’t know what to do,” Trump said, “They want to be politically correct, and it makes them weak.”

On the contrary, I would imagine some choice words were being uttered in European capitals as they waded through the string of insults.
What has Trump said?
First up, the US president criticised European leaders for failing to end the war between Russia and Ukraine.
“They talk but they don’t produce. And the war just keeps going on and on,” he said.
The fact that the Russians have shown no real commitment to stopping the invasion they started is not mentioned.
Instead, the blame is laid squarely at the feet of Ukraine and its allies in Europe.
“I think if I weren’t president, we would have had World War III,” Trump suggested, while concluding that Moscow is in the stronger position.

Does he have a point?
Critics claim that the White House has emboldened the Kremlin and brought Putin in from the cold with a summit and photo opportunities.
Trump highlights the fact that his return to office forced many European NATO members to increase defence spending drastically.
On this, he is correct – the growing insecurity around how long America can be relied on has brought security into sharp focus.
German Chancellor Friedrich Merz on Tuesday claimed some of its contents were unacceptable from a European point of view.
“I see no need for America to want to save democracy in Europe. If it was necessary to save it, we would manage it on our own,” he told a news conference in Rhineland-Palatinate, the German state where Trump’s paternal grandfather was born.

For this reason, Merz reiterated that Europe and Germany must become more independent of America for their security policies.
However, he noted, “I say in my discussions with the Americans, ‘America first’ is fine, but America alone cannot be in your interests.”
For his part, while Trump said he liked most of Europe’s current leaders, he warned they were “destroying” their countries with their migration policies.
He said: “Europe is a different place, and if it keeps going the way it’s going, Europe will not be…in my opinion, many of those countries will not be viable countries any longer. Their immigration policy is a disaster”.
He added: “Most European nations… they’re decaying.”
Again, the comments echoed his security strategy, which warned immigration risked “civilisation erasure” in Europe.
There’s no doubt immigration is a major concern for many of the continent’s leaders and voters.

However, irregular crossings into the EU fell 22% in the first 10 months of 2025 according to Frontex, a fact which seems to have passed the president and his team by.
“Within a few decades at the latest, certain Nato members will become majority non-European”, his security document warned.
It also suggested “cultivating resistance” in Europe “to restore former greatness” leading to speculation about how America might intervene in European politics.
Trump appeared to add further clarification on Tuesday, saying while he did not “want to run Europe”, he would consider “endorsing” his preferred candidates in future elections.

This comment will also ruffle feathers on the continent where the European Council President has already warned Trump’s administration against interfering in Europe’s affairs.
“Allies do not threaten to interfere in the domestic political choices of their allies,” Antonio Costa said on Monday.
“The US cannot replace Europe in what its vision is of free expression… Europe must be sovereign.”
So, what will happen now, and how will Europe’s leaders respond?
If you are hoping for a showdown, you will likely be disappointed.
Like him or loathe him, Europe’s leaders need Trump.
They need the might of America and want to try to secure continued support for Ukraine.
While the next few days will be filled with politely scripted statements or rejections of the president’s comments, most of his allies know on this occasion they are probably best to grin and bear it.
A “cheap ceasefire” between Ukraine and Russia – with Kyiv forced to surrender land – would create an “expensive peace” for the whole of Europe, Norway’s foreign minister has warned.
Espen Barth Eide explained this could mean security challenges for generations, with the continent’s whole future “on the line”.
It was why Ukraine, its European allies and the US should seek to agree a common position when trying to secure a settlement with Vladimir Putin, the top Norwegian diplomat told Sky News in an interview during a visit to London on Tuesday.
“I very much hope that we will have peace in Ukraine and nobody wants that more than the Ukrainians themselves,” Mr Eide said.
“But I am worried that we might push this to what in quotation marks is a ‘cheap ceasefire’, which will lead to a very expensive peace.”
Explaining what he meant, Mr Eide said a post-war era follows every conflict – big or small.

Inside Ukraine’s underground military HQ
How that plays out typically depends upon the conditions under which the fighting stopped.
“If you are not careful, you will lock in certain things that it will be hard to overcome,” he said.
“So if we leave with deep uncertainties, or if we allow a kind of a new Yalta, a new Iron Curtain, to descend on Europe as we come to peace in Ukraine, that’s problematic for the whole of Europe. So our future is very much on the line here.”
He said this mattered most for Ukrainians – but the outcome of the war will also affect the future of his country, the UK and the rest of the continent.
“This has to be taken more seriously… It’s a conflict in Europe, it has global consequences, but it’s fundamentally a war in our continent and the way it’s solved matters to our coming generations,” the Norwegian foreign minister said.
Russia ‘will know very well how to exploit vagueness’
Asked what he meant by a cheap ceasefire, he said: “If Ukraine is forced to give up territory that it currently militarily holds, I think that would be very problematic.
“If restrictions are imposed on future sovereignty. If there’s vagueness on what was actually agreed that can be exploited. I think our Russian neighbours will know very well how to exploit that vagueness in order to keep a small flame burning to annoy us in the future.”
Progress being made on peace talks
Referring to the latest round of peace talks, initiated by Donald Trump, Mr Eide signalled that progress was being made from an initial 28-point peace plan proposed a couple of weeks ago by the United States that favoured Moscow over Kyiv.
That document included a requirement for the Ukrainian side to give up territory it still holds in eastern Ukraine to Russia and Mr Eide described it as “problematic in many aspects”.
But he said: “I think we’ve now had a good conversation between Ukraine, leading European countries and the US on how to adapt and develop that into something which might be a good platform for Ukraine and its allies to go to Russia with.
“We still don’t know the Russian response, but what I do know is the more we are in agreement as the West, the better Ukraine will stand.”
