摘要

背景:关于首次感染后严重急性呼吸综合征冠状病毒2 (SARS-CoV-2)再感染率差异的数据很少。目的:我们根据4个再感染窗口:29-45天、46-60天、61-90天和≥91天，检查了科威特全国SARS-CoV-2再感染数据。方法:这是一项人群水平的回顾性队列研究，于2020年3月31日至2021年3月31日进行。我们审查了先前从COVID-19中恢复并检测为阴性的人的第二次RT-PCR检测结果阳性的证据。结果:29 ~ 45天再感染率为0.52%，45 ~ 60天再感染率为0.36%，61 ~ 90天再感染率为0.29%，≥91天再感染率为0.20%。再感染时间间隔最短(29-45天)个体的平均年龄(标准差[SD])显著高于其他所有组的平均年龄——43.3岁(SD 17.5)比39.0岁(SD 16.5)，间隔46-60天P = 0.037;61 ~ 90天间隔38.3年(SD 16.5)， P = 0.002;39.2年(SD 14.4)，间隔≥91天P = 0.001。结论:该人群中SARS-CoV-2再感染少见。年龄越大，再感染时间越短。

Nationwide study of rates of reinfection with SARS-CoV-2 among adults in Kuwait.

Background: Data are scarce on differences in the rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) reinfection after the first infection.

Aims: We examined nationwide data on SARS-CoV-2 reinfection in Kuwait according to four-time windows to reinfection: 29-45 days, 46-60 days, 61-90 days, and ≥ 91 days.

Methods: This was a population-level retrospective cohort study conducted between 31 March 2020 and 31 March 2021. We reviewed evidence of second positive RT-PCR test results for those who had previously recovered from COVID-19 and tested negative.

Results: Reinfection rates were: 0.52% for reinfection window 29-45 days, 0.36% for 45-60 days, 0.29% for 61-90 days, and 0.20% for ≥ 91 days. The mean age (standard deviation [SD]) of individuals with the shortest reinfection time interval (29-45 days) was significantly older than the mean age of all other groups - 43.3 years (SD 17.5) compared with: 39.0 years (SD 16.5), P = 0.037 for 46-60-day interval; 38.3 years (SD 16.5), P = 0.002 for 61-90-day interval; and 39.2 years (SD 14.4), P = 0.001 for ≥ 91-days interval.

Conclusion: SARS-CoV-2 reinfection was uncommon among this adult population. Older age was associated with a shorter time to reinfection.
