Abstract

Objectives: To explore the epidemiological characteristics of respiratory syncytial virus (RSV) infection in children in Nanchang and its correlation with climate environmental factors.

Methods: The clinical data were collected from children with acute respiratory infection in Nanchang who were tested for RSV at Jiangxi Provincial Children's Hospital from January 2019 to December 2023, along with climate environmental data for the same period. The epidemiological characteristics of RSV and their correlation with climate environmental factors were investigated.

Results: A total of 178 127 children underwent RSV testing from January 2019 to December 2023, with a positive detection rate of 8.35% (14 873/178 127). The positive detection rate in males was 8.92% (10 137/113 660), which was higher than that in females (7.35%, 4 736/64 467). The differences in RSV positive detection rates among different age groups were statistically significant (P<0.001), with the highest rate observed in the 0 to <3 months age group (14.38%, 3 328/23 142). Peaks in RSV positive detection occurred during winter and spring periods in 2019, 2020, and 2022, while in 2023, it occurred in spring and summer periods, with no seasonality noted in 2021. The RSV positive detection rate showed a positive correlation with average humidity, average atmospheric pressure, monthly PM_2.5, and monthly carbon monoxide levels (P<0.05), while it showed a negative correlation with average wind speed, average temperature, and maximum 8-hour ozone levels (P<0.05).

Conclusions: In Nanchang, the RSV positive detection rate in children with acute respiratory infection is higher in males than in females. Among children of all age groups, the infants aged 0 to <3 months have the highest detection rate of RSV. RSV infection predominantly occurs in winter and spring periods. Lower temperatures, lower wind speeds, higher humidity, and elevated levels of PM_2.5 and carbon monoxide may increase the risk of RSV infection in children.

南昌市儿童呼吸道合胞病毒感染的流行病学特征及其与气候环境因素的相关性

目的：探讨南昌市儿童呼吸道合胞病毒（RSV）感染的流行病学特征及其与气候环境因素的关系。方法：收集2019年1月至2023年12月在江西省儿童医院进行呼吸道合胞病毒检测的南昌市急性呼吸道感染患儿的临床资料及同期气候环境资料。探讨RSV流行病学特征及其与气候环境因素的相关性。结果：2019年1月至2023年12月，共有178 127名儿童接受了RSV检测，阳性检出率为8.35%（14 873/178 127）。男性阳性检出率为8.92%(10 137/113 660)，高于女性（7.35%,4 736/64 467）。不同年龄组间RSV阳性检出率差异有统计学意义（P2.5），月一氧化碳水平差异有统计学意义（pp2.5）。结论：南昌市急性呼吸道感染患儿RSV阳性检出率男性高于女性。在所有年龄组的儿童中，0至2.5岁的婴儿和一氧化碳可能增加儿童感染呼吸道合胞病毒的风险。
