As both infections are deemed to share similarities at presentation, it would be useful to distinguish COVID-19 from dengue in the context of co-epidemics. Hence, we performed a retrospective cohort study to identify predictors of both infections.<h4>Methodology/principal findings</h4>All the subjects suspected of COVID-19 between March 23 and May 10, 2020, were screened for COVID-19 within the testing center of the University hospital of Saint-Pierre, Reunion island. The screening consisted in a questionnaire surveyed in face-to-face, a nasopharyngeal swab specimen for the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) reverse transcription polymerase chaPLoS neglected tropical diseasese0008879https://www.ebi.ac.uk/biostudies/studies/S-EPMC8102001biostudies-literatureDistinguishing non severe cases of dengue from COVID-19 in the context of co-epidemics: A cohort study in a SARS-CoV-2 testing center on Reunion island.PMC8102001Accot FAndry FJoubert ALegrand FKoumar YLevin CBertolotti AManaquin RPoubeau PGerardin PfalseDistinguishing non severe cases of dengue from COVID-19 in the context of co-epidemics: A cohort study in a SARS-CoV-2 testing center on Reunion island.<h4>Background</h4>As coronavirus 2019 (COVID-19) is spreading globally, several countries are handling dengue epidemics.
