China’s official count 0 2.5 million 83,150 deaths Model based on Shanghai outbreak 1.6 million deaths LOW ESTIMATE HIGH ESTIMATE Estimate using travel patterns 970,000 deaths Estimate using recent testing data 1.5 million deaths Estimate based on U.S. death rates 1.1 million deaths China’s official count 0 2.5 million 83,150 deaths Model based on Shanghai outbreak 1.6 million deaths LOW EST. But China’s official Covid death toll for the entire pandemic remains strikingly low: 83,150 people as of Feb. 9. Four separate academic teams have converged on broadly similar estimates: China’s Covid wave may have killed between a million and 1.5 million people. Why official data underrepresents China’s outbreak83,150 deaths China’s official count on Feb. 9 0 2.5M 83,150 deaths China’s official count on Feb. 9 0 2.5 millionChina has a narrow definition of what counts as a Covid-19 death. But the work was unwavering in its ultimate conclusion: Ending the “zero Covid” policy was likely to overwhelm the health care system, producing an estimated 1.6 million deaths.

The results wouldn’t be published until a few months after Covid arrived in early 2020, but Columbia University’s Jeffrey Shaman and colleagues produced a study in 2016-18 showing that only 5% of cold-symptom sufferers and 21% of people with flu-like symptoms sought medical attention. Had the data been available in the pandemic’s earliest days, it would have reinforced what should have been everybody’s first assumption after reflecting on their own medical behavior. If most people with mild symptoms weren’t seeing doctors, not only was Covid less deadly than being reported, it was likely already out of the bag globally and unstoppable even in countries where it had yet to be formally identified.
Mai mult, este cel mai cuprinzător și mai îndelungat studiu al memoriei imune la coronavirus până în prezent. La opt luni de la infecție, majoritatea persoanelor care și-au revenit, au încă suficiente celule imune pentru a evita virusul și a preveni bolile, arată noile date. Ideea a fost de a construi o imagine a răspunsului imun în timp. Îngrijorările cu privire la cât de mult persistă imunitatea la coronavirus au fost declanșate în principal de cercetarea acelor viruși care cauzează răceli comune. Până acum, cel puțin, a remarcat el, reinfectările cu coronavirus par a fi rare.
