Inferring Public Health Policies From Epidemiology and Whole Genome Sequencing of Invasive Pneumococcal Isolates From a Surveillance Network.

The authors discuss a study by Beall and colleagues on invasive pneumococcal disease (IPD) identified through the U.S. Centers for Disease Control and Prevention's Active Bacterial Core surveillance (ABCs) network during 2018. Topics include serotype 3 as the most common serotype causing IPD in all age groups in 2018 according to Beall and colleagues, a high proportion of IPD occurring in people experiencing homelessness (PEH), and important observation on IPD clusters in the PEH population.
