Abstract

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.

科威特成年人中SARS-CoV-2再感染率的全国性研究

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。

The mission of the Journal is to contribute to improving health in the Eastern Mediterranean Region by publishing and publicising quality health research and information with emphasis on public health and the strategic health priorities of the Region. It aims to: further public health knowledge, policy, practice and education; support health policy-makers, researchers and practitioners; and enable health professionals to remain informed of developments in public health. The EMHJ: -publishes original peer-reviewed research and reviews in all areas of public health of relevance to the Eastern Mediterranean Region -encourages, in particular, research related to the regional health priorities, namely: health systems strengthening; emergency preparedness and response; communicable diseases; noncommunicable diseases and mental health; reproductive, maternal, child health and nutrition -provides up-to-date information on public health developments with special reference to the Region.
