The RSV epidemic varied year-on-year, with annual and biannual epidemics observed. The three approaches identified similar RSV epidemic in Hong Kong, a total of 9 RSV epidemics were found. The RSV epidemics mainly occurred from mid-February to late September, with an average duration of approximately 6 months during the study years. We found that mean temperature was positively associated with RSV positive rate, while mean dew point temperature showed a negative association.\u003Cbr>Conclusions: RSV epidemic varied year-on-year in Hong Kong, the 2 % threshold is recommended as an alert threshold for RSV epidemics. A One Health perspective might enhance future prevention strategies by incorporating broader environmental and intersectoral factors. |  |\n\n1. Introducion  \nRespiratory syncytial virus (RSV) is one of the main causes of acute lower respiratory infection (ALRI), and ALRI is one of the leading causes of morbidity and mortality in young children aged \u003C5 years, especially in infants aged under 1 year [1,2]. Shi et al. estimated that there were 3.2 million RSV-associated hospitalizations in children aged \u003C5 years, especially among infants aged less than 6 months [3]. And RSV can cause a substantial disease burden in adults, especially in older adults aged ≥65 years [4]. There were 336,000 RSV-associated hospitalizations in older adults globally [1]. Early-life infection with RSV has been well documented to increase the risk of recurrent wheezing and asthma  \n[5], and reinfection with RSV can occur throughout life.  \nRSV epidemics show varied seasonal patterns in different areas and different years around the world. In temperate areas, RSV usually has an annual epidemic and peaks during winter months, while for subtropical and tropical areas, RSV seasonality varied from annual epidemic and se","cbCaik9UnAEqUSpg","https://ap.wps.com/l/cbCaik9UnAEqUSpg","pdf",4239077,9,"English","# Background\n# Introduction\n# Methods\n## Data and study period (2014–2023)\n## Seasonality detection approaches\n## Statistical modeling\n# Results\n## RSV epidemic patterns\n## Associations with meteorological factors\n# Conclusions","[{\"question\":\"What is the main aim of the study in Hong Kong from 2014 to 2023?\",\"answer\":\"To characterize RSV seasonality and quantify associations between RSV positivity and meteorological factors, so stakeholders can optimize timing of prevention and immunization strategies.\"},{\"question\":\"Which methods were used to explore RSV seasonality in the study?\",\"answer\":\"Three approaches were applied: the 50th percentile method, the average annual percentage (AAP) method, and the 2% threshold method.\"},{\"question\":\"What seasonal window and duration were observed for RSV epidemics?\",\"answer\":\"RSV epidemics mainly occurred from mid-February to late September, with an average duration of approximately 6 months across the study years.\"},{\"question\":\"What meteorological factors were associated with RSV positive rate?\",\"answer\":\"Mean temperature showed a positive association with RSV positivity, while mean dew point temperature showed a negative association.\"}]","The seasonality of respiratory syncytial virus and its associations with meteorological factors in Hong Kong, 2014-2023 | PDF",1790658037,23,{"code":4,"msg":86,"data":104},[105,109,113,117,122,127,130,135,139,142,146],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":106,"show_sort_weight":107,"slug":108},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":110,"show_sort_weight":111,"slug":112},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":114,"show_sort_weight":115,"slug":116},"Exam",70,"exam",{"id":118,"doc_module":4,"doc_module_name":25,"category_name":119,"show_sort_weight":120,"slug":121},5,"Comic",60,"comic",{"id":123,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":125,"slug":126},6,"Technology",50,"technology",{"id":90,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":128,"slug":129},40,"healthcare",{"id":131,"doc_module":4,"doc_module_name":25,"category_name":132,"show_sort_weight":133,"slug":134},8,"Research & Report",30,"research-report",{"id":96,"doc_module":4,"doc_module_name":25,"category_name":136,"show_sort_weight":137,"slug":138},"Religion & Spirituality",20,"religion-spirituality",{"id":137,"doc_module":4,"doc_module_name":25,"category_name":140,"show_sort_weight":137,"slug":141},"World Cup","world-cup",{"id":143,"doc_module":4,"doc_module_name":25,"category_name":144,"show_sort_weight":143,"slug":145},10,"Lifestyle","lifestyle",{"id":147,"doc_module":4,"doc_module_name":25,"category_name":148,"show_sort_weight":118,"slug":149},19,"General","general"]
