2013-2024年北京市和成都市流感统计数据

数据为日数据，包含成都、北京两个城市，流感报告病例数、流感样病例数、流感样病例数乘以流感阳性率三种指标，不同指标和城市的时间范围不同，整体时间范围为2013-2024年。
详细说明：数据为处理后的数据，原始数据取自流感报告病例数、流感样病例数和流感阳性率。流感报告病例数为日数据，来源于全国法定传染病报告信息系统，流感样病例数为日数据，来源于北京和成都的哨点医院流感样病例监测系统，流感阳性率为周数据，来源于北京和成都的病原学监测系统。原始数据采集后进行了进一步的处理，对于日数据，避免周末效应，做7日移动平均处理。流感样病例数乘以流感阳性率作为一个复合指标，计算方式为将周阳性率乘以当周每日的流感样病例数。所有数据均经过数量级的脱敏处理，数据的原始形态没有变化。

This dataset comprises daily data for two cities, Chengdu and Beijing, covering three indicators: the number of reported influenza cases, the number of influenza-like illness (ILI) cases, and a composite indicator calculated as the product of ILI cases and influenza positive rate. The time ranges vary across different indicators and cities, with the overall time span ranging from 2013 to 2024.

Detailed description: This is a preprocessed dataset, whose raw data is collected from three separate sources. The reported influenza cases are daily data obtained from the National Notifiable Infectious Disease Reporting Information System. The ILI cases are daily data collected from the ILI surveillance systems of sentinel hospitals in Beijing and Chengdu. The influenza positive rate is weekly data sourced from the etiological surveillance systems of Beijing and Chengdu.
Following raw data collection, further processing was performed: a 7-day moving average was applied to the daily datasets to mitigate weekend effects. The composite indicator (product of ILI cases and influenza positive rate) is calculated by multiplying the weekly influenza positive rate by the daily ILI cases within the corresponding week. All data has undergone magnitude-based anonymization processing, while the original data structure remains unchanged.
