Abstract

Background: Invasive pneumococcal disease (IPD), which is caused by Streptococcus pneumoniae, has been a nationally notifiable disease in Canada since 2000.This report summarizes the demographics, serotypes and antimicrobial resistance of IPD isolates collected in Canada in 2023. Methods:The Public Health Agency of Canada's National Microbiology Laboratory (Winnipeg, Manitoba) collaborates with provincial and territorial public health laboratories to conduct national surveillance of IPD.Serotypes and minimum inhibitory concentrations were obtained from whole genome sequencing data. Results:The incidence of IPD in Canada was 10.2 cases per 100,000 population in 2022, increasing from the low rate of 5.6 cases per 100,000 population in 2021.A total of 4,760 IPD isolates were collected during 2023.The most common serotypes overall were 3 (12.3%,n=587), 4 (12.2%,n=580), 22F (8.2%, n=391) and 9V (7.1%, n=340).Serotypes 4 (7.1%-12.2%,p
