By now, we all know the coronavirus has a tendency to morph as it spreads, creating different strains and variants along the way – with differing symptoms and varying infection rates. We’ve had the dreaded Omicron XE, the Centaurus and now, experts are weighing in on the ‘XBB’ Covid-19 variation, warning that sensationalist news reports (which have referred to it as the ‘nightmare’ strain) are ‘irresponsible’.
What is the XBB Covid variant?
While the new XBB variant, which is making its way through Southeast Asia, has seen case numbers double in a day in the likes of Singapore, those in the medical field are saying it isn’t anything especially new, although it does appear to be “immune evasive” against some vaccines. The World Health Organisation (WHO) issued a statement on Wednesday saying the XBB variant has been detected in 26 countries in total, but did not say specifically which ones. However, we do know that a small number of cases have already been observed in England.
“[Referring to it as the ‘nightmare’ strain] is irresponsible reporting because it’s impossible to know what all these variants mean,” UC Berkeley infectious disease expert, John Swartzberg, told the San Francisco Chronicle this week.
“We are seeing a slew of new variants that are using a similar approach to survive — they are finding ways to evade the way we get immunity from vaccines and previous infection with changes on the spike protein,” he added. “XBB is no different from the others.”
Thankfully, other authority figures have stressed that at the moment “there is no evidence that XBB causes more severe illness” when looking at Singapore as a case study. This, it’s believed, is due to a high uptake of booster vaccines in the sovereign island country.
It’s thought that this particular strain of Covid-19 is combination of two different strains of Omicron, and the WHO have implied that XBB looks as though it is the most antibody-evasive variant so far, something they’ve gleaned through “laboratory evidence”, but that the bivalent boosters (which use a formula targeting both the original Covid strain and Omicron variations) have shown promising results.
There are also ‘spin off strains’ of XBB, known as XBB.1, XBB.2, and XBB.3.
It’s reported that the symptoms of the XBB variant are similar to its Omicron cousins:
Cough
Cold
Low-level fever
Sore throat
Body aches
For those who have underlying health conditions, such as diabetes, symptoms may be more severe.

Ukraine on Sunday denounced as dangerous lies suggestions from Russia that it was preparing to use a "dirty bomb". Its western allies also dismissed the allegations from Moscow, just hours after Russia went public with the claims. In conversations with his British, French and Turkish counterparts, Russian Defence Minister Sergei Shoigu conveyed "concerns about possible provocations by Ukraine with the use of a 'dirty bomb'", Moscow said. Russia did not mention the alleged "dirty bomb" allegation in its statement following Shoigu's call with Pentagon chief Lloyd Austin. "If Russia calls and says that Ukraine is allegedly preparing something, it means one thing: Russia has already prepared all this," President Volodymyr Zelensky said in a video address on social media. "I believe that now the world should react as harshly as possible." Earlier Sunday, Ukraine's Foreign Minister Dmytro Kuleba denounced Moscow's claims as "absurd" and "dangerous". "Russians often accuse others of what they plan themselves," he added. A British defence ministry statement said Defence Secretary Ben Wallace had "refuted these claims and cautioned that such allegations should not be used as a pretext for greater escalation". And in Washington, National Security Council spokeswoman Adrienne Watson dismissed Moscow's "transparently false" claim. "The world would see through any attempt to use this allegation as a pretext for escalation," she added. – 'Vile strikes' – Russia also announced Sunday that it had destroyed a depot in central Ukraine storing over 100,000 tonnes of aviation fuel. Kyiv's energy operator meanwhile said scheduled power cuts had been introduced in the Ukrainian capital due to Russia's repeated strikes on the nation's power network. The blackouts started from 11:13 am (0813 GMT) with consumers in Kyiv divided into three groups "disconnected for a certain period of time", energy company DTEK said. DTEK reiterated calls for residents to use electricity "sparingly" and for businesses to limit their use of external lighting. More than one million Ukrainian households have lost electricity following recent Russian strikes, according to the Ukrainian presidency, at least a third of the country's power stations having been destroyed ahead of winter. Zelensky condemned the "vile strikes" in comments late Saturday, after Russian attacks caused power cuts across the country. – 'Save your strength' – In the southern Ukrainian city of Kryvyi Rig, deputy mayor Sergiy Miliutin was dealing with emergencies and power outages from his underground bunker, used as a venue for a children's martial arts competition. "I've reached a point where I just survive on my drive. You have to stay level-headed and save your strength. No one knows how long this will all last," he told AFP. The intensification of Russian strikes on Ukraine, particularly energy facilities, came after the bridge linking the annexed Crimea peninsula to mainland Russia was partially destroyed by an explosion earlier this month. It was another major setback for Moscow's forces, battling to contain a Ukrainian counter-offensive in the south and east of the country. French President Emmanuel Macron said Sunday that it was for Ukrainians to decide when "peace is possible", in comments made in Rome at the start of a peace summit. Ukraine reported three deaths in an overnight Russian artillery strike in the Toretsk area, a governor of the eastern Donetsk region said. Inside Russia, two lines of defence have been built in the border region of Kursk to deal with any possible attack, a local governor said on Sunday. On Saturday Vyacheslav Gladkov, the governor in the neighbouring Russian border region of Belgorod, said the construction of defence structures had begun. Gladkov said two civilians had been killed in strikes there Saturday, and that 15,000 people had been left without electricity. – Kherson evacuations – Meanwhile Ukraine's SBU intelligence service said it had detained two officials of Ukrainian aircraft engine maker Motor Sich on suspicion of working with Russia. The SBU said management at the company's plant in Ukraine's southern Zaporizhzhia region — partly controlled by Russian forces — had colluded with Russian state-owned defence conglomerate Rostec. The suspects had supplied Russia with Ukrainian aircraft engines that were used to make and repair attack helicopters, the SBU said. In the southern Ukrainian region of Kherson, which Russia claims to have annexed, pro-Moscow officials on Saturday urged residents to leave "immediately" amid a "tense situation" at the front. Kherson, the region's main city, was the first to fall to Moscow's troops and retaking it would be a major prize in Ukraine's counter-offensive. A Moscow-installed official in Kherson, Kirill Stremousov, told Russian news agency Interfax on Saturday that around 25,000 people had left Kherson city to the left bank of the Dnipro River. Ukraine has denounced the removal of residents from Kherson, describing them as "deportations". bur-imm/raz/jj/lcm

Former Chinese president Hu Jintao was unexpectedly led out of Saturday's closing ceremony of the Communist Party Congress in a dramatic moment that disrupted the highly choreographed event.
Pro-Russian authorities on Saturday urged residents in the southern Kherson region, which Moscow claims to have annexed, to leave the main city "immediately" in the face of Kyiv's advancing counter-offensive. It comes as President Volodymyr Zelensky said Russia had launched 36 rockets overnight in a "massive attack" on Ukraine, following reported strikes on energy infrastructure that resulted in power outages across the country. And Japanese Prime Minister Fumio Kishida became the latest world leader to reproach Moscow for its talk of using nuclear weapons. Kyiv's forces have been advancing along the west bank of the Dnipro river, towards the Kherson region's eponymous main city. Kherson was the first major city to fall to Moscow's troops, and retaking it would be a major prize in Ukraine's counter-offensive. In recent days, Russia has been moving residents in the region — which Moscow claims to have annexed in September — east to Russia, in efforts Kyiv has denounced as "deportations". "Due to the tense situation on the front, the increased danger of mass shelling of the city and the threat of terrorist attacks, all civilians must immediately leave the city and cross to the left bank" of the Dnipro river, the region's pro-Russian authorities announced on social media. A Moscow-installed official in Kherson, Kirill Stremousov, told Russian news agency Interfax on Saturday that around 25,000 people had made the crossing. Sergiy Khlan, the Ukrainian deputy head of the Kherson region, said Russians were removing property and documents from banks and the passport office as they withdrew. Ukraine's general staff said Moscow's forces had abandoned two more settlements in Kherson and were evacuating medical personnel from a third, accusing them of looting local civilians. – A 'serious threat' – Earlier Saturday, Japan's Kishida denounced Moscow's comments regarding the possible use of nuclear weapons in the Ukraine conflict. "Russia's act of threatening the use of nuclear weapons is a serious threat to the peace and security of the international community and absolutely unacceptable," he said. The 77-year period of no nuclear weapons use "must not be ended", said Kishida, speaking in Australia. Since Russia invaded Ukraine in February, Putin has made several thinly veiled threats about his willingness to deploy tactical nuclear weapons. Earlier this month, the European Union foreign policy chief Josep Borrell warned that the Russian army would be "annihilated" if Russia launched such an attack. Washington has also warned Moscow of "catastrophic" consequences should they use such weapons. Japan is the only country ever to have been hit with nuclear weapons: the US atomic bomb dropped on Hiroshima on August 6, 1945, which killed 140,000 people, and the second US bomb on Nagasaki, three days later, which killed 74,000 people. – 'Afraid for our lives' – At a train station in the town of Dzhankoy in the north of Crimea, a peninsula that Moscow annexed from Ukraine in 2014, Kherson residents were boarding a train for southern Russia, an AFP reporter saw Friday. "We are leaving Kherson because heavy shelling started there, we are afraid for our lives," said Valentina Yelkina, a pensioner travelling with her daughter. More than a million households in Ukraine have been left without electricity following Russian strikes on energy facilities across the country, the deputy head of the Ukrainian presidency Kyrylo Tymoshenko said on Saturday. Fresh Russian strikes targeted energy infrastructure in Ukraine's west, the national operator said earlier, with officials in several regions of the war-scarred country reporting power outages as winter approaches. Russians "carried out another missile attack on energy facilities of the main networks of Ukraine's western regions", Ukraine's energy operator Ukrenergo said on social media. "These are vile strikes on critical objects," said Zelensky. "The world can and must stop this terror." Power outages were reported in other parts of the country and local officials repeated calls to reduce energy use. Some parts of Ukraine have already cut their electricity use by up to 20 percent, according to Ukrenergo. "Saturday in Ukraine starts with a barrage of Russian missiles aimed at critical civilian infrastructure," Ukraine's Foreign Minister Dmytro Kuleba said on Twitter. He once again urged Kyiv's allies to hasten the delivery of air defence systems. In the Russian Belgorod region bordering Ukraine, at least two civilians were killed in strikes on Saturday, according to the local governor Vyacheslav Gladkov. Nearly 15,000 people were left without electricity, he added. Russia last week reported a "considerable increase" in Ukrainian fire into its territory, saying attacks had largely concentrated on Belgorod region and neighbouring regions of Bryansk and Kursk. bur-imm/jj/ah
