Streptococcus Pneumoniae Serotype Distribution in Chile, 2016-2023

Chilean invasive pneumococcal disease (IPD) cases from 2016 to 2023, collected from two public hospitals. The dataset includes demographic, clinical, vaccination, and serotype data for pediatric and adult patients. It was created by Angélica R. Bravo and published on figshare in May 2026.

Use Cases

• Analyze serotype replacement trends based on the predominance of non-vaccine serotypes mentioned in the description
• Model vaccine coverage gaps based on the reported pediatric (75.5%) and adult (6.3%) vaccination rates
• Assess mortality risk factors based on the 20.4% adult mortality rate reported
• Compare prevalent serotypes between age groups based on the listed pediatric (19A, 24F, 6C, 3) and adult (3, 23A, 23B, 19A, 6C) serotypes

Strengths

• Covers an 8-year time range (2016-2023) for longitudinal analysis
• Includes specific vaccination coverage figures (75.5% in children, 6.3% in adults) and a mortality rate (20.4% in adults)
• Identifies the most frequent serotypes for pediatric and adult populations

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• Data is limited to two hospitals in Chile, which may affect generalizability
