Background: Many sub-Saharan African patients receive clinical care from extramurally-supported research and surveillance. During the COVID-19 pandemic, pausing these activities reduces patient care, surveillance, and research staff employment, increasing pandemic losses. In Oyo State, Nigeria, we paused a multi-country invasive salmonellosis surveillance initiative and a rural clinical bacteriology project. Objective: Working with research partners raises health facility con- cerns about SARS-CoV-2 transmission risks and incurs infection pre- vention costs, so we developed and implemented re-opening plans to protect staff and patients and help health facilities deliver care.Methods: Our reopening plan included appointing safety and personal protective equipment (PPE) managers from existing project staff cadres, writing new standard operating procedures, implementing extensive assessed training, COVID-19 testing for staff, procuring and managing PPE, and providing secondary bacteraemia blood culture support for COVID-19 patients in State isolation facilities. Results: Surveillance data showed that the pandemic reduced care access and negatively affected patient unsupervised antibacterial use. The re-opening plan repurposed human and material resources from national and international extramurally-supported programs to mitigate these effects on public health. Conclusions: A structured reopening plan restarted care, surveillance, and infection prevention and control.
