Abstract：
OBJECTIVE: To investigate the incidence rate of urinary tract infections (UTIs) among febrile infants aged ≤60 days before, during, and after the COVID-19 pandemic.
METHODS: We conducted a retrospective study in 2 Swedish paediatric emergency departments between 2014 and 2022. We included full-term infants aged ≤60 days with fever without source. We calculated the annual incidence rate of UTI per 1000 births.
RESULTS: We included 1589 full-term infants with fever without source. In 2020, 89 infants were evaluated in the emergency department versus 203-259 in 2017-2019. In 2020, the incidence rate of UTI was 1.43 per 1000 births/year versus 2.18-2.37 in 2017-2019. The median age, sex, fever duration, and urine testing were similar between the years 2017 and 2020.
CONCLUSIONS: The number of febrile infants who presented to the paediatric emergency department and the incidence rate of UTIs decreased in 2020. This decrease might imply a systematic misdiagnosis of UTIs in infants with febrile viral infections. A more selective urine testing approach for febrile, previously healthy, infants should be considered to mitigate UTI misdiagnosis and its potential harmful effects.

摘要：
目的:了解≤60d发热婴儿尿路感染的发生率,during,在COVID-19大流行之后。
方法：我们在2014年至2022年之间在2个瑞典儿科急诊科进行了回顾性研究。我们包括年龄≤60天的足月婴儿，无来源发热。我们计算了每1000名新生儿的UTI年发病率。
结果：我们纳入了1589例无来源发热的足月婴儿。2020年，急诊科评估了89名婴儿，而2017-2019年为203-259名。2020年，UTI的发病率为1.43/1000出生/年，而2017-2019年为2.18-2.37。年龄中位数,性别,发烧持续时间，2017年和2020年的尿液检测相似。
结论：到儿科急诊科就诊的发热婴儿数量和尿路感染的发生率在2020年有所下降。这种减少可能意味着对发热性病毒感染的婴儿的UTI的系统性误诊。一种更具选择性的发热尿液检测方法，以前很健康,婴儿应考虑减轻UTI误诊及其潜在有害影响.
