Determine age-specific infection fatality rates for COVID-19 to inform public health policies
and communications that help protect vulnerable age groups. Studies of COVID-19 …

Importance The degree to which children and adolescents are infected by and transmit
severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is unclear. The role of …

Children less than 18 years of age account for an estimated 2%–5% of reported severe
acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) cases globally. Lower prevalence …

Epidemics generally spread through a succession of waves that reflect factors on multiple
timescales. On short timescales, superspreading events lead to burstiness and …

Population‐based prevalence surveys of Covid‐19 contribute to establish the burden of
infection, the role of asymptomatic and mild infections in transmission, and allow more …

Abstract COVID-19 (Corona Virus Disease 2019) is a severe respiratory syndrome currently
causing a human global pandemic. The original virus, along with newer variants, is highly …

Background We aimed to estimate the seroprevalence of SARS-CoV-2 infection in France
and to identify the populations most exposed during the first epidemic wave. Methods …

This paper assesses the age specificity of the infection fatality rate (IFR) for COVID-19. Our
benchmark meta-regression synthesizes the age-specific IFRs from four recent large-scale …

Background A year following the onset of the COVID-19 pandemic, new infections and
deaths continue to increase in Europe. Serological studies, through providing evidence of …

The ability to preferentially protect high-risk groups in COVID-19 is hotly debated. Here, the
aim is to present simple metrics of such precision shielding of people at high risk of death …
