Background: As of the 31st of January 2021, there had been 102,399,513 confirmed cases of COVID-19 worldwide, with 2,217,005 deaths reported to WHO. The goal of this study is to uncover the spatiotemporal patterns ofCOVID- 19in Ethiopia, which will aid in the planning and implementation of essential preventative measures.

Methods: We obtained data onCOVID-19cases reported in Ethiopia from November 23 to December 29, 2021, from an Ethiopian health data website that is open to the public. Kulldorff’s retrospective space-time scan statistics were utilized to detect the temporal, geographical, and spatiotemporal clusters ofCOVID-19at the county level in Ethiopia, using the discrete Poisson probability model.

Results: In Ethiopia, between November 23 and December 29, 2021, a total of 22,199COVID-19cases were reported.

TheCOVID-19cases in Ethiopia were strongly clustered in spatial, temporal, and spatiotemporal distribution, according to the results of Kulldorff’s scan statistics. The most likely Spatio-temporal cluster (LLR=70369.783209, RR=412.48, P 0.001) was mostly concentrated in Addis Ababa and clustered between 2021/11/1 and 2021/11/30.

Conclusion: From November 23 to December 29, 2021, this study found three large COVID-19 space-time clusters in Ethiopia, which could aid in future resource allocation in high-risk locations for COVID-19 management and prevention.
