Since the first reports in summer 2020, SARS-CoV-2 reinfections have raised concerns about the immunogenicity of the virus, which will affect SARS-CoV-2 epidemiology and possibly the burden of COVID-19 on our societies in the future. This study provides data on the frequency and characteristics of possible reinfections, using the French national COVID-19 testing database. The Omicron variant had a large impact on the frequency of possible reinfections in France, which represented 3.8% of all confirmed COVID-19 cases since December 2021.
自2020年夏季首次报告以来，SARS-CoV-2再次感染引发了人们对该病毒免疫原性的担忧，这将影响SARS-CoV-2的流行病学，并可能影响未来COVID-19对我们社会造成的负担。本研究利用法国国家COVID-19检测数据库，提供了关于可能再次感染的频率和特征的数据。奥密克戎变异株对法国可能再次感染的频率产生了重大影响，自2021年12月以来，再次感染病例占所有确诊COVID-19病例的3.8%。
