We assessed the risk of reinfection among all residents in South Korea who tested positive for coronavirus disease 2019 from January to August 2022. Children 5-11 years [adjusted hazard ratio (aHR) = 2.20], and 12-17 years old (aHR = 2.00), were at higher risk; whereas 3-dose vaccination (aHR = 0.20) lowered the risk of reinfection.
我们评估了 2022 年 1 月至 8 月期间韩国所有经新冠病毒检测呈阳性的居民的再感染风险。5-11 岁儿童（校正风险比[aHR] = 2.20）和 12-17 岁儿童（aHR = 2.00）风险更高；而 3 剂疫苗接种（aHR = 0.20）降低了再感染的风险。
