Currently, little is known about the status of PCV\u20102 in Africa. In this study, a total of 408 archived DNA samples collected from pigs in Burkina Faso, Cameroon, Cape Verde, Ethiopia, the Democratic Republic of the Congo, Mozambique, Nigeria, Senegal, Tanzania and Zambia between 2000 and 2018 were screened by PCR for the presence of PCV\u20102. Positive amplicons of the gene encoding the viral capsid protein (ORF2) were sequenced to determine the genotypes circulating in each country. Four of the nine currently known genotypes of PCV\u20102 were identified (i.e. PCV\u20102a, PCV\u20102b, PCV\u20102d and PCV\u20102\u00a0g) with more than one genotype being identified in Burkina Faso, Ethiopia, Nigeria, Mozambique, Senegal and Zambia. Additionally, a phylogeographic analysis which included 38 additional ORF2 gene sequences of PCV\u20102s previously identified in Mozambique, Namibia and South Africa from 2014 to 2016 and 2019 to 2020 and available in public databases, demonstrated the existence of several African\u2010specific clusters and estimated the approximate time of introduction of PCV\u20102s into Africa from other continents. This is the first in\u2010depth study of PCV\u20102 in Africa and it has important implications for pig production at both the small\u2010holder and commercial farm level on the continent.<\/jats:p>","DOI":"10.1111\/tbed.14400","type":"journal-article","created":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T09:59:25Z","timestamp":1637661565000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Porcine
