Several features of low-transmission regions are hypothesized as explanations: higher chance of symptoms and treatment seeking, better treatment access, less within-host competition among clones, and lower rates of recombination. Here, we test whether importation of drug-resistant parasites is more likely to lead to successful emergence and establishment in low-transmission or high-transmission periods of the same epidemiological setting, using a spatial, individual-based stochastic model of malaria and drug-resistance evolution calibrated for Burkina Faso. Upon controlling for the timing of importation of drug-resistant genotypes and examination of key model variables, we found that drug-resistant genotypes imported during the low transmission season were, (1) more susceptible to stochastic extinction due to the action of random genetic drift, and (2) more likely to lead to establishment of drug resistance when parasites are able to survive early stochastic loss due to drift. This implies that rare importation events are more likely to lead to establishment if they occur during a high-transmission season, but that constant importation (e.g., neighboring countries with high levels of resistance) may produce a greater risk during low-transmission periods.\n                <\/jats:p>","DOI":"10.1101\/2023.10.20.563204","type":"posted-content","created":{"date-parts":[[2023,10,23]],"date-time":"2023-10-23T23:30:32Z","timestamp":1698103832000},"source":"Crossref","is-referenced-by-count":2,"title":["Role of Seasonal Importation and Random Genetic Drift on Selection for Drug-Resistant Genotypes of\n                  <i>Plasmodium falciparum<\/i>\n                  in High Transmission Settings"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8757-483X","authenticated-orcid":false,"given":"Robert J.","family":"Zupko","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9988-5712","authenticated-orcid":false,"given":"Joseph L.","family":"Servadio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5118-8432","authenticated-orcid":false,"given":"Tran Dang","family":"Nguyen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thu Nguyen-Anh","family":"Tran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3046-8547","authenticated-orcid":false,"given":"Kien Trung","family":"Tran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1530-1493","authenticated-orcid":false,"given":"Anyir\u00e9kun Fabrice","family":"Som\u00e9","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0830-9630","authenticated-orcid":false,"given":"Maciej F.","family":"Boni","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2023102705000485000_2023.10.20.563204v1.1","doi-asserted-by":"publisher","DOI":"10.1038\/nature00813"},{"key":"2023102705000485000_2023.10.20.563204v1.2","doi-asserted-by":"publisher","DOI":"10.1126\/science.1098876"},{"key":"2023102705000485000_2023.10.20.563204v1.3","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pmed.1001040"},{"key":"2023102705000485000_2023.10.20.563204v1.4","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMp1403340"},{"key":"2023102705000485000_2023.10.20.563204v1.5","doi-asserted-by":"publisher","DOI":"10.1038\/nature12876"},{"key":"2023102705000485000_2023.10.20.563204v1.6","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMoa1314981"},{"key":"2023102705000485000_2023.10.20.563204v1.7","unstructured":"World Health Organization. 2019 World Malaria Report 2019.
