Roses-S: Statement From The World Health Organization On The Reporting Of Seroepidemiologic Studies For Sars-Cov-2

Well-designed population-based seroepidemiologic studies can be used to refine estimates of infection severity and transmission, and are therefore an important component of epidemic surveillance. However, the interpretation of the results of seroepidemiologic studies for SARS-CoV-2 has been hampered to date principally by heterogeneity in the quality of the reporting of the results of the study and a lack of standardized methods and reporting. We provide here the ROSES-S: Reporting of Seroepidemiologic studies-SARS-CoV-2. This is an updated checklist of 22 items that should be included in the reporting of all SARS-CoV-2 seroepidemiologic studies, irrespective of study design.
