‘Ferocious’ Covid outbreak in Beijing traced to raucous bar | China

Authorities in Beijing are racing to contain a Covid outbreak traced to a 24-hour bar known for cheap liquor and big crowds, with millions of people facing mandatory testing and thousands under targeted lockdowns.

The outbreak of 228 cases linked to the Heaven Supermarket bar, which had just reopened as curbs in the Chinese capital eased last week, highlights how difficult it will be for China to make a success of its “zero Covid” policy as much of the rest of the world tries to live with the virus.

The re-emergence of infections is also raising fresh concerns about the outlook for the world’s second-largest economy. China is only just shaking off the economic impact of a two-month lockdown of Shanghai that caused disruption to global supply chains.

“Epidemic prevention and control is at a critical juncture,” said Liu Xiaofeng, a Beijing health official, at a news conference on Monday, adding that the outbreak linked to the bar in the city’s biggest district, Chaoyang, was “still developing”.

In a show of how seriously authorities are taking the situation, the Chinese vice-premier Sun Chunlan visited the bar and said Covid prevention measures would need to be strengthened, state media reported.

People infected in the outbreak live or work in 14 of the capital’s 16 districts, authorities have said.

Dine-in service at Beijing restaurants resumed on 6 June after more than a month in which the city of 22 million people enforced various coronavirus restrictions. Many shopping centres, gyms and other venues were closed, parts of the public transport system were suspended and millions of people were urged to work from home.

Chaoyang kicked off a three-day mass testing campaign among its roughly 3.5 million residents on Monday. About 10,000 close contacts of the bar’s patrons have been identified and their residential buildings put under lockdown. Some planned school reopenings in the district have been postponed.

Queues snaked around testing sites on Monday for more than 100 metres, according to Reuters witnesses. Large metal barriers had been installed around several residential compounds, with people in hazmat suits spraying disinfectant.

Other nearby businesses under lockdown included the Paradise Massage and Spa parlour. Police tape and security staff blocked the entrance to the parlour on Sunday and authorities said a handful of people would be locked in temporarily for checks.

Last week as dine-in curbs were lifted, Heaven Supermarket Bar, modelled as a large self-service liquor store with chairs, sofas and tables, reclaimed its popularity among young, noisy crowds starved of socialising and parties during Beijing’s Covid restrictions.

The bar, where patrons check aisles to grab anything from local heavy spirits to Belgian beer, is known among Beijing revellers for its tables littered with empty bottles, and customers falling asleep on sofas after midnight.

Officials have not commented on the exact cause of the outbreak, nor explained why they are not yet reinstating the level of curbs seen last month.

The state-backed Beijing Evening News wrote on Monday that the outbreak had arisen from loopholes and complacency in epidemic prevention, and said that if it grew, “consequences could be serious, and would be such that nobody would want to see”.

Shanghai endured two months of lockdown, with restrictions lifted less than a fortnight ago. There was relief among its residents on Monday after mass testing for most of its 25 million people at the weekend showed only a small rise in daily cases.

But frustrations have continued to simmer about the damage the lockdown caused, especially to residents’ livelihoods. On Monday, shopkeepers in the city centre held up signs and shouted demands for rent refunds, according to videos widely posted on Chinese social media. The rare protest had dissipated by the time Reuters visited on Monday afternoon, and there was a heavy police presence in the area.

Ferocious ‘penis worms’ were the hermit crabs of the ancient seas

The Cambrian period (543 million to 490 million years ago) brought the first great explosion of biodiversity to Earth, with the ancestors of practically all modern animals first appearing. One of the most feared among them was the penis worm.

Technically known as priapulids — named for Priapus, the well-endowed Greek god of male genitals — penis worms, as they’re commonly known, are a division of marine worms that have survived in the world’s oceans for 500 million years. Their modern descendants live largely unseen in muddy burrows deep underwater, occasionally freaking out fishermen with their floppy, phallus-shaped bodies. But fossils dating back to the early Cambrian show that penis worms were once a scourge of the ancient seas, widely distributed around the world and in possession of extendible, fang-lined mouths that could make a snack out of the poor marine creature that crossed them.

But, fearsome as they were, penis worms themselves were not without fear. In a new study published Nov. 7 in the journal Current Biology, researchers discovered four priapulid fossils that were nestled into the cone-shaped shells of hyoliths, a long-extinct group of marine animals.

Because all of the worms were found in the same type of shell, and in roughly the same position, it’s likely that the worms had appropriated the shells as their homes, just as modern hermit crabs do, the researchers said.

If that’s the case, then it would seem that penis worms invented the “hermit” lifestyle hundreds of millions of years before the crustaceans that made it famous.

“The only explanation that made sense was that these shells were their homes — something that came as a real surprise,” study co-author Martin Smith, an associate professor of paleontology at Durham University in England, said in a statement via email.

The team discovered the four hermit penis fossils in the collections of the Guanshan fossil deposits, from southern China. These fossil deposits, dating to the early Cambrian (about 525 million years ago) are famous for preserving not just hard structures such as teeth and shells, but also soft tissue — like the bodies of priapulids — which are much rarer to find in the fossil record.

In each shell, the worm’s bottom sits squished into the bottom of the cone, while the worm’s head and mouth dangle out over the side — sort of like a melting swirl of soft-serve ice cream. According to the researchers, the fossil region contained dozens of other empty shells, but no other free-living priapulids, suggesting the connection between the two was no mere accident. Furthermore, each worm fit snugly in its sheath, suggesting the creatures chose their shells for permanent protection from Cambrian predators, rather than as temporary refuge.

This type of “hermiting” behavior has never been seen in priapulids before, nor in any species before the Mesozoic era (250 million to 65 million years ago), the researchers wrote. For Smith, it’s “mind-boggling” that this complex behavior could have emerged so soon after the great burst of biodiversity known as the Cambrian explosion, more than 500 million years ago. In the harsh world of the early ocean, it seems even fearsome penis worms had to get creative.
