The COVID-19 pandemic in Nigeria is part of the worldwide pandemic of coronavirus disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

An effective surveillance system is needed to efficiently control disease outbreaks. We therefore assessed the capacity of the Covid-19 surveillance system for early detection of outbreak, monitor the spread and progress of the pandemic and effectiveness of measures instituted to control the outbreak.
