COVID-19 Case Age Distribution: Correction for Differential Testing by Age.

ABSTRACT:

Background

Despite expected initial universal susceptibility to a novel pandemic pathogen like SARS-CoV-2, the pandemic has been characterized by higher observed incidence in older persons and lower incidence in children and adolescents.

Objective

To determine whether differential testing by age group explains observed variation in incidence.

Design

Population-based cohort study.

Setting

Ontario, Canada.

Participants

Persons diagnosed with SARS-CoV-2 and those tested for SARS-CoV-2.

Measurements

Test volumes from the Ontario Laboratories Information System, number of laboratory-confirmed SARS-CoV-2 cases from the Integrated Public Health Information System, and population figures from Statistics Canada. Demographic and temporal patterns in inciden
