The adenovirus detection rate is <10% throughout the year in South Korea; however, during the summer of 2023, it showed an unusual increase. We analyzed the adenovirus detection rate using data from the Korea Respiratory Integrated Surveillance System before and after coronavirus disease (COVID-19) collected from 2019 to week 36 of 2023. Before the COVID-19 outbreak in 2019, the mean detection rate was 8.2%, which decreased to 6.1% during the COVID-19 pandemic from 2020 to 2022. In 2023, the mean detection rate was 14.3% in week 36 and the highest in week 34, at 42.2%, and adenovirus was predominantly detected in the summer. The detection rate by age group showed substantially high activity among 0-12-yr-olds after the pandemic. This age group had a steady mean rate of 9.5% during the pandemic, without seasonality. In 2023, the detection rate surged in the 0-6-yr and 7-12-yr age groups, peaking at 61.6% and 57.1%, respectively. The dominant epidemic serotypes were HAdV-1 and HAdV-2 during and HAdV-3 after the pandemic. The multifaceted non-pharmaceutical interventions during the COVID-19 pandemic considerably impacted the prevalence of common respiratory viruses and complicated respiratory virus patterns after the pandemic. Constant surveillance is crucial for epidemic preparedness to monitor the possible surge of certain respiratory viruses.
韩国全年腺病毒检出率<10%；然而，2023 年夏季，其检出率却异常升高。我们分析了 2019 年至 2023 年第 36 周韩国呼吸道综合监测系统在新冠疫情前后的数据，以了解腺病毒的检出率。在 2019 年新冠疫情爆发之前，平均检出率为 8.2%，2020 年至 2022 年疫情期间降至 6.1%。2023 年第 36 周的平均检出率为 14.3%，其中第 34 周最高，为 42.2%，腺病毒主要在夏季检出。按年龄组划分的检出率显示，疫情后 0-12 岁儿童的活跃度显著升高。该年龄段在疫情期间的平均检出率稳定在 9.5%，没有季节性。2023 年，0-6 岁和 7-12 岁年龄组的检出率飙升，分别达到 61.6%和 57.1%。流行期间的主要流行血清型为 HAdV-1 和 HAdV-2，疫情后为 HAdV-3。新冠疫情期间实施的多方面非药物干预措施，极大地影响了常见呼吸道病毒的流行情况，也使呼吸道病毒模式变得复杂。为了应对某些呼吸道病毒可能出现的激增，持续监测对于疫情防范至关重要。
