专家预测：针对新冠疫情的隔离措施可能要持续到2022年

研究发现，未来五年的病例总数和所需的隔离水平很大程度上地取决于目前总体的感染水平以及被感染者是否都能获得免疫力，如果获得了免疫力，这种免疫力可以持续多久。作者警告称，这些都是很大的未知因素，因此准确预测疫情长期发展态势是不可能的。

If immunity is permanent, Covid-19 could disappear for five or more years after the first outbreak, the paper suggests. If people have immunity for about a year, as is seen for some other circulating coronaviruses, an annual outbreak cycle would be the most likely outcome.

研究报告指出，如果被感染者能获得永久的免疫力，那么新冠肺炎疫情将会在第一次暴发至少五年后消失。如果人们的免疫力能持续一年左右，就像其他一些循环流行的冠状病毒一样，那么一年一度的暴发周期将是最可能发生的结果。

Prof Marion Koopmans, the head of virology at the Erasmus University Medical Centre in Rotterdam, whose team is studying the antibody response of those infected, said complete and permanent protection would be unusual for a respiratory virus.

荷兰鹿特丹伊拉斯谟大学医学中心病毒学主任马里恩·科普曼斯教授说，对于呼吸道病毒而言，完全且永久的免疫并不常见。他的团队正在研究被感染者的抗体反应。

"What you would expect to see – hope to see – is that people who have had it once ... the disease would get milder,” she said before the latest paper was released.
