Temporal rise in the proportion of younger adults and older adolescents among coronavirus disease (COVID-19) cases following the introduction of physical distancing measures, Germany, March to April 2020. Eurosurveillance 25, no. 17 (2020):pii=2000596. https://doi.org/10.2807/1560-7917.ES.2020.25.17.20005961560-7917http://nrs.harvard.edu/urn-3:HUL.InstRepos:42667695Using data on coronavirus disease (COVID-19) cases in Germany from the Robert Koch Institute, we found a relative increase with time in the prevalence in 15–34 year-olds (particularly 20–24-year-olds) compared with 35–49- and 10–14-year-olds (we excluded older and younger ages because of different healthcare seeking behaviour). This suggests an elevated role for that age group in propagating the epidemic following the introduction of physical distancing measures.en-USCOVID-19age groupsyounger adultsolder adolescentsJournal Article2020-05-1810.2807/1560-7917.es.2020.25.17.2000596
