The risk of maternal infection was lower among travellers compared to residents: 25.0% (n = 36\/144) versus 42.9% (n = 309\/721); aRR 0.6; 95% CI 0.5\u20130.8. Risk factors associated with maternal infection among travellers were travelling during the epidemic period (i.e., June 2015 to December 2016) (aOR 29.4; 95% CI 3.7\u2013228.1), travelling to the Caribbean Islands (aOR 3.2; 95% CI 1.2\u20138.7) and stay duration &gt;2 weeks (aOR 8.7; 95% CI 1.1\u201371.5). Adverse pregnancy outcomes were observed in 8.3% (n = 3\/36) of infected travellers and 12.7% (n = 39\/309) of infected residents. Overall, the risk of maternal infections is lower among travellers compared to residents and related to the presence of ongoing outbreaks and stay duration, with stays &lt;2 weeks associated with minimal risk in the absence of ongoing outbreaks.<\/jats:p>","DOI":"10.3390\/v13020341","type":"journal-article","created":{"date-parts":[[2021,2,22]],"date-time":"2021-02-22T20:42:51Z","timestamp":1614026571000},"page":"341","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Maternal
