Old Covid-19 incidence rate

### Actions of Public Health France Public Health France’s mission is to improve and protect the health of populations. During the health crisis linked to the COVID-19 outbreak, Santé publique France is responsible for monitoring and understanding the dynamics of the epidemic, anticipating the various scenarios and putting in place actions to prevent and limit the transmission of this virus on national territory. ### The Tracking Information System (SI-DEP) The new screening information system (SI-DEP), which has been in operation since 13 May 2020, is a secure platform where the results of the laboratory tests carried out by all city and hospital laboratories for SARS-COV2 are systematically recorded. The creation of this information system is authorised for a period of 6 months from the end of the state of health emergency by application of [Decree No 2020-551 of 12 May 2020](https://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000041869923) on the information systems referred to in Article 11 of Law No 2020-546 of 11 May 2020 extending the state of health emergency and supplementing its provisions. ### Description of data This dataset provides information at the departmental and regional level: — the daily and weekly incidence rate per age group; — the daily and weekly standardised incidence rate; — the sliding standardised incidence rate. This dataset provides information at the national level: — the daily and weekly incidence rate by age group and sex; — the daily and weekly standardised incidence rate; — the sliding standardised incidence rate. The incidence rate corresponds to the number of positive tests per 100,000 inhabitants. It shall be calculated as follows: (100000 * number of positive cases)/Population **Accuracy**: — From 29/08 onwards, laboratory data indicators (SI-DEP) show rates of incidence, positivity and screening adjusted for screenings conducted at airports upon arrival of international flights. — For more information, see the methodological note available in the resources. **Limits**: — Only the biological tests of persons for whom the residence department could be located are shown on the maps. Persons whose department could not be traced in the SIDEP data are counted only at the whole French level. As a result, the sum of the tests indicated in the departments or regions is less than the number of tests indicated in France. — The time limit for repeating tests may exceed 9 days in some cases. The indicators are adjusted daily according to the receipt of the results. ### Notable changes Since 8 December, after verifying the quality of the reported data, all results of RT-PCR or Antigenic tests have been included in the production of national and territorial epidemiological indicators (incidence rates, positivity rates and screening rates) relevant to the monitoring of the COVID-19 outbreak. On the other hand, the epidemic is prolonging in time and screening capacities have increased, leading to an increasing frequency of people tested several times. Thus, an adjustment of the methods of splitting for patients benefiting from repeated tests and therefore the definition of the persons tested was necessary. Public Health France, in its patient-centred epidemiological approach, has therefore adapted its methods to ensure that these indicators reflect, in particular, the proportion of infected people among the population tested. These developments have no impact on the trends and interpretation of the dynamics of the epidemic, which remain the same. More precise test data (impact and positivity) are also published by [Santé publique France](https://www.data.gouv.fr/fr/organizations/sante-publique-france/) (SI-DEP data).### 法国公共卫生署的工作职能 法国公共卫生署（Public Health France）的使命是改善并保障全体民众的健康水平。在新冠疫情暴发引发的公共卫生危机期间，该机构负责监测并研判疫情传播态势，预判各类疫情演化场景，并制定防控行动方案，以在法国境内预防并限制该病毒的传播。 ### 追踪信息系统（SI-DEP） 自2020年5月13日起投入运行的新型冠状病毒（SARS-CoV-2）筛查信息系统（SI-DEP），是一个安全可靠的平台，可系统性收录法国所有城市实验室与医院实验室开展的SARS-CoV-2检测结果。 根据2020年5月11日颁布的第2020-546号法律（该法律延长了公共卫生紧急状态并补充相关条款）中第11条关于信息系统的规定，本信息系统的设立获批，有效期为公共卫生紧急状态结束后6个月，依据为2020年5月12日颁布的第2020-551号政令（https://www.legifrance.gouv.fr/affichTexte.do?cidTexte=JORFTEXT000041869923）。 ### 数据集说明 本数据集提供省域与大区层面的信息： — 按年龄组划分的日度与周度发病率； — 日度与周度标准化发病率； — 滑动标准化发病率。 本数据集同时提供全国层面的信息： — 按年龄组与性别划分的日度与周度发病率； — 日度与周度标准化发病率； — 滑动标准化发病率。 发病率指每10万居民中的阳性检测人数，计算公式如下： (100000 × 阳性病例数) / 总人口数 **数据准确性说明**： — 自8月29日起，实验室数据指标（SI-DEP）已纳入针对国际航班入境旅客机场筛查的校正后发病率、阳性率与筛查率数据。 — 如需了解更多信息，请参阅资源中提供的方法学说明。 **数据局限性说明**： — 本数据集的可视化地图仅展示了可确定居住省份的受检者的检测结果。无法在SI-DEP数据中追溯到所属省份的受检者，仅纳入法国全国层面的统计范畴。因此，各省份或区域的检测总数量低于法国全国的检测总数量。 — 部分场景下，重复检测的时间间隔可能超过9天。各项指标将根据检测结果的接收情况每日进行校正。 ### 重要更新说明 自12月8日起，在验证上报数据的质量后，所有RT-PCR检测与抗原检测结果均已纳入与新冠疫情监测相关的全国及区域流行病学指标（发病率、阳性率与筛查率）的计算体系。与此同时，随着疫情持续蔓延与筛查能力提升，民众多次接受检测的频率显著增加。因此，针对多次接受检测的患者的检测结果拆分方法，以及受检人群的定义，均需作出相应调整。法国公共卫生署秉持以患者为中心的流行病学研究理念，对相关计算方法进行了优化，以确保各项指标能够准确反映受检人群中的感染比例。上述调整不会影响疫情态势的趋势分析与解读，相关结论保持不变。更精准的检测数据（包括影响率与阳性率）可通过法国公共卫生署官方平台（https://www.data.gouv.fr/fr/organizations/sante-publique-france/）获取（SI-DEP数据集）。
