China’s COVID-19 surge raises odds of new coronavirus mutant
Associated PressCould the COVID-19 surge in China unleash a new coronavirus mutant on the world? “When we’ve seen big waves of infection, it’s often followed by new variants being generated,” Ray said. Ray compared the virus to a boxer that “learns to evade the skills that you have and adapt to get around those.” One big unknown is whether a new variant will cause more severe disease. “Much of the mildness we’ve experienced over the past six to 12 months in many parts of the world has been due to accumulated immunity either through vaccination or infection, not because the virus has changed” in severity, Ray said. China’s plan to track the virus centers around three city hospitals in each province, where samples will be collected from walk-in patients who are very sick and all those who die every week, Xu Wenbo of the Chinese Center for Disease Control and Prevention said at a briefing Tuesday.
