The Chinese city of Xian remained under lockdown for a fifth day yesterday, as authorities reported 150 new local symptomatic COVID-19 cases for Sunday, a slight decrease from the previous day.
Case numbers in Xian, home to 13 million people, remain tiny compared with many clusters overseas, but authorities have imposed tough curbs on leaving the city and travel within it, because of Beijing’s drive to immediately contain outbreaks.
Authorities have not announced any infection caused by the Omicron variant of SARS-CoV-2 in Xian, where there were 635 confirmed COVID-19 cases from Dec. 9 to Sunday.

The 150 local symptomatic cases on Sunday compared with 155 a day earlier, and accounted for most of the 162 new domestic infections in China.
China reported a total of 158 domestically transmitted symptomatic cases for Sunday.
The new case number for Sunday marks the highest nationwide count of local symptomatic infections since the daily bulletin provided by the Chinese National Health Commission started to classify asymptomatic carriers separately from the end of March last year.
In Xian, residents cannot leave the city without approval from employers or local authorities.
From Thursday, households have been allowed to send only one person to shop for necessities every two days. Other family members cannot leave home unless they have essential jobs or urgent matters to attend to, approved by employers or communities.
Xian authorities yesterday urged residents to stay home except for having their sample taken in a new round of citywide testing.
Xian has also launched a citywide disinfection campaign, with workers spraying pathogen-killing solutions onto roads and buildings. People have been advised not to touch plants or building surfaces.
Jin Dong-yan (金冬雁), a virologist at the University of Hong Kong, said the mass disinfection of outdoor air and surfaces seemed unnecessary given the low risk of people catching COVID-19 from outdoor surfaces with so few people outside.
“This is shooting mosquitoes with cannon,” Jin said.
However, he said that disinfection of indoor surfaces, especially in places visit by infected people, is necessary.
An American scientist convicted of lying to US authorities about payments from China while he was at Harvard University has rebuilt his research lab in Shenzhen, China, to pursue technology the Chinese government has identified as a national priority: embedding electronics into the human brain. Charles Lieber, 67, is among the world’s leading researchers in brain-computer interfaces. The technology has shown promise in treating conditions such as amyotrophic lateral sclerosis and restoring movement in paralyzed people. It also has potential military applications: Scientists at the Chinese People’s Liberation Army have investigated brain interfaces as a way to engineer super soldiers by boosting
Indonesian police have arrested 13 people after shocking images of alleged abuse against small children at a daycare center went viral, sparking outrage across the nation, officials said on Monday. Police on Friday last week raided Little Aresha, a daycare center in Yogyakarta on Java island, following a report from a former employee. CCTV footage circulating on social media showed children, most younger than two, lying on the floor wearing only diapers, their hands and feet bound with rags. The police have confirmed that the footage is authentic. Police said they also found 20 children crammed into a room just 3m by 3m. “So
A grieving mother has ended her life at a clinic in Switzerland four years after the death of her only child. Wendy Duffy, 56, a physically healthy woman, died at the Pegasos clinic in Basel after struggling to cope with the death of her 23-year-old son, Marcus. The former care worker, from the West Midlands, England, had previously attempted to take her own life. The case comes as assisted dying would not become law in England and Wales after proposed legislation, branded “hopelessly flawed” by opponents, ran out of time. Ruedi Habegger, the founder of Pegasos, described Duffy’s death as
From post offices and parks to stations and even the summit of Mount Fuji, Japan’s vending machines are ubiquitous, but with the rapid pace of inflation cooling demand for their drinks, operators are being forced to rethink the business. Last month beverage giant DyDo Group Holdings announced it would remove about 20,000 vending machines — about 7 percent of their stock nationwide — by January next year, to “reconstruct a profitable network.” Pokka Sapporo Food & Beverage, based in Nagoya, also said last month it would sell its 40,000-machine operation to Osaka-based Lifedrink Co. “The strength of the vending machine
