  Zhao Xiaoqing, right, with Zhao Fei in Xianyang, China. Zhao Xiaoqing When Zhao Xiaoqing first met Zhao Fei on a blind date, the sparks didn’t really fly. When they met for a second time at his home in northwest China in December, it lasted longer than they both expected. Facing a new outbreak of coronavirus cases, the health authorities announced a lockdown so sudden and severe that she didn’t have time to scurry home. So for nearly four weeks, Zhao Xiaoqing has lived in the city of Xianyang, in Shaanxi Province, with the family of Zhao Fei, a man she had barely known. (They share a last name but are not related.) “Initially, I was quite worried about things being awkward,” said Ms. Zhao, who is from Baoji, about 93 miles away, or a two-hour drive by car. “But I got along well with his family.” Chinese officials have employed swift lockdowns across the country as one of its top strategies to rapidly stamp out infections. Last month, officials  locked down 13 million people in the ci

  The stunning Covid vaccines manufactured by Pfizer-BioNTech and Moderna drew upon long-buried discoveries made in the hopes of ending past epidemics.

Johnathon Kelso for The New York Times Thousands of miles from Dr. Barney Graham’s lab in Bethesda, Md., a frightening new coronavirus had jumped from camels to humans in the Middle East, killing one out of every three people infected. An expert on the world’s most intractable viruses, Dr. Graham had been working for months to develop a vaccine, but had gotten nowhere. Now he was terrified that the virus, Middle East Respiratory Syndrome, or MERS, had infected one of his lab’s own scientists, who was sick with a fever and a cough in the fall of 2013 after a pilgrimage to the holy city

MELBOURNE, Australia (AP) — Novak Djokovic remained in limbo even after he was included in the draw for the Australian Open on Thursday, with the tennis star still awaiting a government decision on whether to deport him for not being vaccinated for COVID-19. Despite the cloud hanging over Djokovic’s ability to compete, Australian Open organizers included the top seed in the draw. He is slated to play fellow Serb Miomir Kecmanovic, who is ranked world No. 78., in the opening round next week. No. 1-ranked Djokovic had his visa canceled on arrival in Melbourne last week when his vaccination exemption was rejected, but he won a legal battle on procedural grounds that allowed him to stay in the country. Immigration Minister Alex Hawke has been considering the question since a judge reinstated Djokovic’s visa on Monday. Expectations of a pending decision were raised when Prime Minister Scott Morrison called an afternoon news conference after a national Cabinet meeting. Speculation heightened

Just weeks before hosting the Beijing Winter Olympics, China is battling multiple coronavirus outbreaks in half a dozen cities, with the one closest to the capital driven by the highly transmissible omicron variant. With the success of the Games and China’s national dignity at stake, Beijing is doubling down on its “zero-tolerance” COVID-19 policy.  Across China, more than 20 million people are in some form of lockdown, with many prevented from leaving their homes. Tianjin, only about an hour from Beijing, is on high alert, although it has refrained from imposing a complete lockdown such as that in Xi’an, a city of 14 million.  Instead, it has sealed off several residential communities and universities, canceled almost all flights, suspended high speed train service and closed highways. People leaving the city are required to present negative COVID-19 tests and receive special permission.  The city conducted mass testing for a second time for its 14 million residents on Wednesday, and

  Pandemics do eventually end, even if   omicron   is complicating the question of when this one will. But it won’t be like flipping a light switch: The   world   will have to learn to coexist with a virus that’s not going away. The ultra-contagious omicron mutant is pushing cases to all-time highs and causing chaos as an exhausted world struggles, again, to stem the spread. But this time, we’re not starting from scratch. Vaccines  offer strong protection from serious illness, even if they don’t always prevent a mild infection. Omicron doesn’t appear to be as deadly as some earlier variants. And those who survive it will have some refreshed protection against other forms of the virus that still are circulating — and maybe the  next mutant  to emerge, too. The newest variant is a warning about what will continue to happen “unless we really get serious about the endgame,” said Dr. Albert Ko, an infectious disease specialist at the Yale School of Public Health. “Certainly COVID will be wi
