USMeaslesData

Daily Measles Data Pipeline

---

What It Does

• Downloads the latest measles case data (daily)
• Summarizes 2025 measles cases by U.S. state
• Compares to 2024 totals using a custom table
• Standardizes weeks using MMWR week start dates
• Incorporates CDC supplemental estimates for hospitalizations and deaths
• Outputs:
• USMeaslesCases.csv — weekly cases per state
• YearlyComparison.json — state-level comparison (2024 vs 2025)
• USMeaslesCasesDetails.csv — cleaned summary data from CDC
• CDC_US_WeeklyRashOnset.csv — CDC national rash-onset weekly measles counts for the 2025 MMWR year (2024-12-29 → 2025-12-27).

Automation

• Runs daily at 15:00 UTC via GitHub Actions
