Cohort

Key result

Measles-associated stridor occurred in 12% of pediatric measles cases and was associated with severe clinical presentation, leading to an 89.7% hospital admission rate and a 17.9% PICU admission rate.

Overview

Stridor in measles signals higher hospitalization and PICU risk than typical croup; leaves open whether specific protocols improve outcomes.

Key Points

  • This study aims to characterize the clinical features and prevalence of stridor in patients with measles.
  • Conducted a multicenter retrospective observational cohort study in 3 pediatric emergency departments from August 1 to October 31, 2025.
  • Included patients aged 0 to 17 years with PCR-confirmed measles presenting with stridor.
  • Assessed disease severity using the Westley Croup Score.
  • 12% of measles patients presented with stridor, with a median age of 15 months and 85% unvaccinated.
  • 89.7% required hospitalization and 17.9% were admitted to the pediatric intensive care unit (PICU).
  • The median length of hospital stay was 3 days, with significant respiratory compromise noted in 76.9% of patients.

Population
39 pediatric patients aged 0 to 17 years with PCR-confirmed measles and stridor, evaluated retrospectively across 3 pediatric emergency departments.
O
Outcome
Clinical characteristics including incidence, clinical presentation, admission rate, treatment, and outcome (disease severity assessed using the Westley Croup Score)

Measles-associated stridor is a common (12%) and severe complication of measles in pediatric patients, characterized by high hospitalization and PICU admission rates compared to typical viral croup.

Limitations

  • Retrospective and observational nature preclude ruling out viral or bacterial coinfection in some cases.
  • Small sample size could have compromised the reliability of the analysis.

Oren et al. (2026) conducted a cohort in Measles-associated stridor (n=39). Measles-associated stridor was evaluated on Hospital admission rate. Measles-associated stridor occurred in 12% of pediatric measles cases and was associated with severe clinical presentation, leading to an 89.7% hospital admission rate and a 17.9% PICU admission rate.
