Abstract

Background: The first wave of the Coronavirus Disease 2019 (COVID-19) pandemic began when the first index case was reported in Nigeria on the 27th of February 2020, and since then, more than 68,000 cases of the disease were confirmed, with 1173 deaths as of November 30, 2020.

Main body: Daily situation reports from the Nigeria Centre for Disease Control spanning February 27-November 30, 2020, were fully considered in this review. Further literature search was performed using PubMed and Google Scholar databases for articles related to response measures adopted by Nigeria. The instantaneous reproduction number (R) was then estimated as a metric to investigate the non-pharmaceutical intervention measures. Nigeria responded to COVID-19 pandemic by implementing anti-COVID-19 mitigation strategies in travel restrictions, social distancing, source control, contact tracing, self-isolation, and quarantine, as well as in clinical interventions. Our epidemiological model estimated the R-value of more than 1.0 in Nigeria and in each of all the 36 states and the Federal Capital Territory.

Conclusion: Nigeria implemented containment and mitigation measures in response to the first wave of COVID-19 and these measures may have contributed to the mild COVID-19 outcome in Nigeria compared to the global trend. However, inadequate PCR testing capacity, lack or suboptimal utilization of epidemic metrics like the virus reproduction number (R) to inform decision making, and premature easing of lockdown measures among others were major challenges to the effective implementation of the COVID-19 response measures.
