Abstract：
This article aims to systematize the evidence regarding risk factors associated with COVID-19 reinfection. We conducted a systematic review of all the scientific publications available until August 2022. To ensure the inclusion of the most recent and relevant information, we searched the PubMed and Scopus databases. Thirty studies were reviewed, with a significant proportion being analytical observational case-control and cohort studies. Upon qualitative analysis of the available evidence, it appears that the probability of reinfection is higher for individuals who are not fully immunized when exposed to a new variant, females, those with pre-existing chronic diseases, individuals aged over 60, and those who have previously experienced severe symptoms of the disease or are immunocompromised. In conclusion, further analytical observational case-control studies are necessary to gain a better understanding of the risk factors associated with SARS-CoV-2 (COVID-19) reinfection.
摘要：
本文旨在将与COVID-19再感染相关的危险因素的证据系统化。我们对2022年8月之前所有可用的科学出版物进行了系统审查。为了确保纳入最新和相关的信息，我们搜索了PubMed和Scopus数据库.回顾了30项研究，其中很大一部分是分析性观察性病例对照和队列研究。在对现有证据进行定性分析后，似乎对于暴露于新变体时未完全免疫的个体，再感染的可能性更高，女性,那些患有慢性病的人，60岁以上的人，以及以前经历过严重疾病症状或免疫功能低下的人。总之,为了更好地了解与SARS-CoV-2(COVID-19)再感染相关的危险因素,需要进一步的分析性观察性病例对照研究.
