A country brief that looks at how reforms to Tanzania’s CRVS system have minimized the impact of COVID–19 lockdown measures on service delivery. This country brief for Tanzania is part of the technical paper series: Documenting the role of notification systems in capturing vital data about births and deaths for health surveillance amid a health crisis. The United Nations Economic Commission for Africa, the APAI-CRVS Secretariat, and the Centre of Excellence for CRVS Systems have partnered to support the development of this technical brief series on innovative, good practices facilitating the continuous and universal registration of vital events in Africa. This includes the generation of data for health surveillance during a health crisis, which has consequently mitigated the impact of COVID-19 on the performance of the civil registration systems. The overarching purpose of this technical paper series is to provide inspiration and policy guidance for CRVS programming in the African region in the midst of a global health crisis, such as the COVID-19 pandemic.
