A total of 136 individuals aged 15 years and older with serologically confirmed CHIKV infection were enrolled. Participants were interviewed at 6 months from the onset of symptoms, and self-reported persistent arthralgia (PA) was the main binary outcome. A self-report numeric rating scale (NRS) ranging from 0 to 10 was used to estimate the severity of articular pain<\/italic>.<\/p>\n<p><bold>Results.<\/bold> <italic>The cumulative incidence of PA was 41.9%. Severe pain (NRS \u2265 7) presented in 36.8% of participants with PA. In multiple analysis, individuals aged 40 years and older (risk ratio (RR) = 1.60; 95% confidence interval (CI), 1.03-2.48) and those with articular pain at 3 months post-infection (RR = 3.95; 95% CI, 1.95-8.01) had a significantly increased risk of PA at 6 months from CHIKV infection<\/italic>.<\/p>\n<p><bold>Conclusions.<\/bold> <italic>To the best of our knowledge, this is first report of a CHIKV-associated longterm outcome in Mexico, where the incidence of the infection has been high. This is also the first study in Latin America evaluating several factors associated with the risk of PA. Our findings may be useful in health care settings to stratify the risk of chronic arthralgia secondary to CHIKV infection and to identify patients who would benefit clinically from early medical intervention<\/italic>.<\/p>","DOI":"10.26633\/rpsp.2017.72","type":"journal-article","created":{"date-parts":[[2019,7,22]],"date-time":"2019-07-22T10:48:06Z","timestamp":1563792486000},"page":"1","source":"Crossref","is-referenced-by-count":4,"title":["Persistent arthralgia and related risks factors in laboratory-confirmed cases of Chikungunya virus infection in Mexico"],"prefix":"10.26633","volume":"41","author":[{"given":"Oliver","family":"Mendoza-Cano","sequence":"first","affiliation":[{"name":"University of Colima, School of Civil Engineering, Coquimatlan, Colima, Mexico."},{"name":"oliver@ucol.mx"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Efr\u00e9n","family":"Murillo-Zamora","sequence":"additional","affiliation":[{"name":"University of Colima, School of Medicine, Doctorate in Health Science program, Colima, Colima, Mexico."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjam\u00edn","family":"Trujillo-Hern\u00e1ndez","sequence":"additional","affiliation":[{"name":"University of Colima, School of Medicine, Colima, Colima, Mexico."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ram\u00f3n Alberto","family":"S\u00e1nchez-Pi\u00f1a","sequence":"additional","affiliation":[{"name":"Harvard University, T.H.
