In Europe, individuals under 40 years old make up a small fraction of COVID-19-related deaths and ICU admissions. The majority of severe cases and deaths are among those 70 years and older. Additional measures should be considered to protect older populations.
Objectives: Precise international estimates of the age breakdown of COVID-19-related deaths and intensive-care-unit (ICU) admissions are lacking. We evaluated the distribution of COVID-19-related fatalities and ICU admissions by age groups in Europe. Materials and methods: On April 6, 2020, we systematically reviewed official COVID-19-related data from 32 European countries. We included countries that provided data regarding more than 10 COVID-19-related deaths stratified by age according to pre-specified age groups (i.e., <40, 40-69, >= 70 years). We used random-effects meta-analysis to summarize the data. Results: Thirteen European countries were included in the review, for a total of 31,864 COVID-19-related deaths (range: 27-14,381 per country). In the main meta-analysis (including data from Germany, Hungary, Italy, The Netherlands, Portugal, Spain, Switzerland; 21,522 COVID-19-related fatalities), the summary proportions of individuals <40, 40-69, and >= 70 years old among all COVID-19-related deaths were 0.1% (0.0-0.2; I-2 28.6%), 13.0% (10.8-15.4; I-2 91.5%), and 86.6% (84.2-88.9; I-2 91.5%), respectively. ICU data were available for four countries (France, Greece, Spain, Sweden). The summary proportions of individuals around <40-50, around 40-69, and around >= 60-70 years old among all COVID-19-related ICU admissions were 5.4% (3.4-7.8; I-2 89.0%), 52.6% (41.8-63.3; I-2 98.1%), and 41.8% (32.0-51.9; I-2 99%), respectively. Conclusions: People under 40 years old represent a small fraction of most severe COVID-19 cases in Europe. These results may help health authorities respond to public concerns and guide future physical distancing and mitigation strategies. Specific measures to protect older people should be considered.
