# Rapid Interventions to Limit Outbreak of Invasive Streptococcus pneumoniae in Correctional Facility, North Carolina, USA, 2024

## TL;DR

A Streptococcus pneumoniae outbreak in a North Carolina prison was controlled through movement restrictions and vaccination, but serotype 4 poses challenges for vaccine effectiveness.

## Contribution

The study demonstrates the effectiveness of rapid interventions in controlling an outbreak of Streptococcus pneumoniae serotype 4 in a correctional facility.

## Key findings

- Movement restrictions and 23-valent pneumococcal vaccination halted new cases of Streptococcus pneumoniae.
- Serotype 4 was identified as a challenge for current vaccination strategies in correctional settings.

## Abstract

A Streptococcus pneumoniae serotype 4 outbreak in a North Carolina correctional facility resulted in 14 cases (8 suspected, 1 probable, and 5 confirmed). After implementation of movement restrictions and vaccination with 23-valent pneumococcal polysaccharide vaccine, new cases ceased. Serotype 4 presence in this setting raises challenges for an effective vaccination strategy.
