AI in Public Health and Epidemiology Quiz

Answers and explanations appear as you take the quiz.

1. What does epidemiology primarily study?
   • Patterns and spread of disease in populations
   • The chemical composition of medicines
   • The structure of computer networks
   • The movement of stars through galaxies
2. Which outbreak did BlueDot’s dated notice describe?
   • Measles in a California school
   • Pneumonia of unknown etiology in Wuhan, China
   • A waterborne disease in a Mars habitat
   • A crop disease in rural Iowa
3. What does CDC’s National Wastewater Surveillance System monitor in wastewater samples?
   • The identity of individual infected residents
   • The exact time each person became infected
   • Viral activity and trends, including SARS-CoV-2 at participating sites
   • Whether every infected person will require hospitalization
4. What limitation did the Google Flu Trends analysis identify?
   • 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
5. In CDC’s definition, what does R0 represent?
   • 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?
   • Only genomic sequences and microscope images
   • Only hospital billing data
   • Multilingual online media and airline-travel information
   • Only weather forecasts and road maps
8. How does Nextclade assign a SARS-CoV-2 clade to a genome?
   • By the city where a sample was collected only
   • By asking a language model to invent a lineage name
   • By ranking samples by hospital severity
   • By evaluating characteristic mutations under a phylogenetic clade definition
