Following the first outbreak of COVID-19 in December 2019, several models have been developed to study and understand its transmission dynamics. Although the spread of COVID-19 is being slowed down by vaccination and other interventions, there is still a need to have a clear understanding of the evolution of the pandemic across countries, states and communities. To this end, there is a need to have a clearer picture of the initial spread of the disease in different regions. In this project, we used a simple SEIR model and a Bayesian inference framework to estimate the basic reproduction number of COVID-19 across Africa. Our estimates vary between 1.98 (Sudan) and 9.66 (Mauritius), with a median of 3.67 (90% CrI: 3.31\u20134.12). The estimates provided in this paper will help to inform COVID-19 modeling in the respective countries\/regions.<\/jats:p>","DOI":"10.1371\/journal.pone.0264455","type":"journal-article","created":{"date-parts":[[2022,2,25]],"date-time":"2022-02-25T13:33:45Z","timestamp":1645796025000},"page":"e0264455","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":30,"title":["The basic reproduction number of COVID-19 across Africa"],"prefix":"10.1371","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8854-2335","authenticated-orcid":true,"given":"Sarafa A.","family":"Iyaniwura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Musa","family":"Rabiu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jummy F.","family":"David","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jude D.","family":"Kong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2022,2,25]]},"reference":[{"key":"pone.0264455.ref001","unstructured":"(WHO) WHO.
