This study investigates the associations between different environmental factors relative to climate, infectious outbreaks, and emergency visits or weekly hospital admissions for vaso-occlusive crisis (VOC). The identification of risk factors would lead to better patient care and patient management, and more targeted prevention and therapeutic education for patients with SCD in French Guiana. (2) Methods: This study was performed using data collected from the medicalized information system and emergency medical records of Cayenne General Hospital, between 1 January 2010 and 31 December 2016. ARIMA models were used to investigate the potential impact of weather conditions and flu epidemics on VOC occurrence. (3) Results: During the study period, 1739 emergency visits were recorded among 384 patients, of which 856 (49.2%) resulted in hospitalization, 811 (46.6%) resulted in hospital discharge, and 72 (4.2%) in another orientation. Decreased temperature and decreased humidity were both independent factors associated with an increase of VOC cases (p = 0.0128 and p = 0.0004, respectively). When studying severe VOC (leading to hospitalization, with or without prior emergency visit), 2104 hospital admissions were recorded for 326 patients. The only factor associated with severe VOC, in the multivariate analysis, was flu epidemics (p = 0.0148). (4) Conclusions: This study shows a link between climate, flu epidemics, and VOC in French Guiana. Patient\u2019s awareness of risks related to climate and flu epidemics should be encouraged, as home prevention measures can help avoid painful crises. Moreover, physicians should encourage patients to get immunized for influenza every year.<\/jats:p>","DOI":"10.3390\/ijerph16152724","type":"journal-article","created":{"date-parts":[[2019,7,31]],"date-time":"2019-07-31T11:37:07Z","timestamp":1564573027000},"page":"2724","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Air Drep\u2014A Retrospective Study Evaluating the Influence of Weather Conditions and Viral Epidemics on Vaso-Occlusive Crises in Patients with Sickle Cell Disease Living in French Guiana"],"prefix":"10.3390","volume":"16","author":[{"given":"Marie-Claire","family":"Parriault","sequence":"first","affiliation":[{"name":"Centre d\u2019Investigation Clinique Antilles Guyane, CIC INSERM 1424, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claire","family":"Cropet","sequence":"additional","affiliation":[{"name":"Centre d\u2019Investigation Clinique Antilles Guyane, CIC INSERM 1424, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aniza","family":"Fahrasmane","sequence":"additional","affiliation":[{"name":"Centre d\u2019Investigation Clinique Antilles Guyane, CIC INSERM 1424, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"St\u00e9phanie","family":"Rogier","sequence":"additional","affiliation":[{"name":"Centre d\u2019Investigation Clinique Antilles Guyane, CIC INSERM 1424, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1221-6960","authenticated-orcid":false,"given":"Micha\u00ebl","family":"Parisot","sequence":"additional","affiliation":[{"name":"Sickle Cell Disease Center, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathieu","family":"Nacher","sequence":"additional","affiliation":[{"name":"Centre d\u2019Investigation Clinique Antilles Guyane, CIC INSERM 1424, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"},{"name":"Equipe EA3593, Ecosyst\u00e8mes Amazoniens et Pathologie Tropicale, University of French Guiana, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0624-4180","authenticated-orcid":false,"given":"Narcisse","family":"Elenga","sequence":"additional","affiliation":[{"name":"Sickle Cell Disease Center, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"},{"name":"Equipe EA3593, Ecosyst\u00e8mes Amazoniens et Pathologie Tropicale, University of French Guiana, Cayenne 97300, French Guiana"},{"name":"Department of Pediatrics, Andr\u00e9e Rosemon General Hospital, Cayenne 97300, French Guiana"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,7,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1561","DOI":"10.1056\/NEJMra1510865","article-title":"Sickle Cell Disease","volume":"376","author":"Piel","year":"2017","journal-title":"N.
