Topic:

  • Davies et al. used mathematical modeling to estimate the age-specific susceptibility to SARS-CoV-2 infection and the age-specific fraction of infections that are symptomatic. After fitting their model to data from 6 countries, they estimated that people under the age of 20 years are half as susceptible to infection as those over 20 years of age, 79% of infections among adolescents (age 10-19) are asymptomatic, and 31% of infections among people age 70 and older are asymptomatic.
