Quarterly distribution of dengue incidence and the relative risk estimates by national, zonal levels and by age groups in the western province in Sri Lanka.

Quarterly distribution of dengue cases per 100,000 population in the first (January to March) and the second (April to June) quarter in 2020 compared to that of five-year average (2015 to 2019). The average values are presented with their respective standard deviation (SD). Standardized incidence ratio (SIR) and meta estimated relative risk with 95% confidence interval are presented.本数据集涵盖2020年第一季度（1月至3月）与第二季度（4月至6月）每10万人口登革热病例数的季度分布数据，并将该数据与2015至2019年的五年平均值进行对比。各平均值将附带其对应的标准差（standard deviation, SD）。此外，本数据集还提供了标准化发病率比（standardized incidence ratio, SIR）以及经荟萃分析估计的相对风险及其95%置信区间（95% confidence interval, CI）。
