    • It could only analyze wastewater samples
    • It predicted every influenza case without error
    • It measured hospital admissions from a randomized trial
    • Search-query signals substantially overestimated influenza-like illness in some seasons

    • Expected new infections caused by one infected person in a fully susceptible population without interventions
    • The fraction of people already vaccinated
    • The number of clinical trials per disease
    • The time between two hospital admissions
  6. What does concept drift mean for a public-health prediction model?
    • A model file moves to another computer
    • The data distribution or input-target relationship changes over time
    • A patient changes hospitals
    • A database permanently deletes old records
  7. Which information does the cited BlueDot case study say its system combines for outbreak monitoring?
