Respiratory syncytial virus (RSV) is most common during the rainy season in a number of low- to middle-income tropical settings, a pattern driven by seasonal changes in climate and nutrition. We investigated the seasonality of RSV in the high-income tropical setting of North Queensland, Australia.
We used RSV hospital admissions data from Cairns and Townsville to assess the seasonality of RSV. We examined the seasonal scale associations between selected meteorological exposures and RSV admissions using cross-correlation of weekly data.
In both Cairns and Townsville, RSV admissions were highest in the latter half of the rainy season. In Cairns, RSV admissions were most strongly correlated with rainfall four weeks previously. In Townsville, RSV admissions were most strongly correlated with rainfall six weeks previously.
The seasonality of RSV in the tropical setting of North Queensland appears to be driven by seasonal variations in rainfall. Further research is needed to assess the impact of climate on RSV incidence in the tropics.
在一些低收入和中等收入的热带地区，呼吸道合胞病毒（RSV）在雨季最为常见，这种模式是由气候和营养的季节性变化驱动的。我们调查了澳大利亚北昆士兰高收入热带地区RSV的季节性。
我们使用凯恩斯和汤斯维尔的RSV住院数据来评估RSV的季节性。我们通过每周数据的互相关分析，研究了选定气象暴露与RSV住院之间的季节尺度关联。
在凯恩斯和汤斯维尔，RSV住院率在雨季后半段最高。在凯恩斯，RSV住院与四周前的降雨量相关性最强。在汤斯维尔，RSV住院与六周前的降雨量相关性最强。
北昆士兰热带地区RSV的季节性似乎是由降雨量的季节性变化驱动的。需要进一步研究来评估气候对热带地区RSV发病率的影响。
