High-quality vaccine-preventable disease (VPD) surveillance data are critical for timely outbreak detection and response. In 2019, the World Health Organization (WHO) African Regional Office (AFRO) began transitioning from Epi Info, a free, CDC-developed statistical software package with limited capability to integrate with other information systems, affecting reporting timeliness and data use, to District Health Information Software 2 (DHIS2). DHIS2 is a free and open-source software platform for electronic aggregate Integrated Disease Surveillance and Response (IDSR) and case-based surveillance reporting. A national-level reporting system, which provided countries with the option to adopt this new system, was introduced. Regionally, the Epi Info database will be replaced with a DHIS2 regional data platform. This report describes the phased implementation from 2019 to the present. Phase one (2019-2021) involved developing IDSR aggregate and case-based surveillance packages, including pilots in the countries of Mali, Rwanda, and Togo. Phase two (2022) expanded national-level implementation to 27 countries and established the WHO AFRO DHIS2 regional data platform. Phase three (from 2023 to the present) activities have been building local capacity and support for country reporting to the regional platform. By February 2024, eight of 47 AFRO countries had adopted both the aggregate IDSR and case-based surveillance packages, and two had successfully transferred VPD surveillance data to the AFRO regional platform. Challenges included limited human and financial resources, the need to establish data-sharing and governance agreements, technical support for data transfer, and building local capacity to report to the regional platform. Despite these challenges, the transition to DHIS2 will support efficient data transmission to strengthen VPD detection, response, and public health emergencies through improved system integration and interoperability.

用于疫苗可预防疾病监测的从 Epi Info 迁移到地区卫生信息软件 2 - 世界卫生组织非洲区域，2019-2023 年。


高质量的疫苗可预防疾病 (VPD) 监测数据对于及时发现和应对疫情至关重要。 2019 年，世界卫生组织 (WHO) 非洲区域办事处 (AFRO) 开始从 Epi Info 过渡到地区办事处，Epi Info 是 CDC 开发的免费统计软件包，与其他信息系统集成的能力有限，影响了报告的及时性和数据使用。健康信息软件 2 (DHIS2)。 DHIS2 是一个免费的开源软件平台，用于电子聚合综合疾病监测和响应 (IDSR) 以及基于病例的监测报告。引入了国家级报告系统，为各国提供了采用这一新系统的选择。在区域方面，Epi Info 数据库将被 DHIS2 区域数据平台取代。本报告介绍了2019年至今的分阶段实施情况。第一阶段（2019-2021）涉及开发 IDSR 总体和基于案例的监测包，包括在马里、卢旺达和多哥国家进行试点。第二阶段（2022年）将国家级实施范围扩大到27个国家，并建立了WHO AFRO DHIS2区域数据平台。第三阶段（从 2023 年至今）活动一直在建设当地能力并支持国家向区域平台报告。截至 2024 年 2 月，47 个非洲区域国家中有 8 个国家采用了综合 IDSR 和基于病例的监测方案，其中两个国家已成功将 VPD 监测数据转移到非洲区域区域平台。挑战包括人力和财力资源有限、需要建立数据共享和治理协议、数据传输技术支持以及建设向区域平台报告的当地能力。 尽管存在这些挑战，向 DHIS2 的过渡将支持高效的数据传输，通过改进的系统集成和互操作性来加强 VPD 检测、响应和公共卫生紧急情况。
