  8. BioMosaic: Focus

  9. Why Foreign Born? • CDC Division of Global Migration and Quarantine • Initially high infectious disease risk • Tuberculosis • Migration – visits to or visitors from home country • Rates of ID decline to native-born levels as length of stay in US increases • Initially low chronic disease risk • Diabetes, obesity risk increases with US residence

  10. Demography • US Census – ACS 2005-2009 • Foreign-born socio-economic variables • Population (by age, sex, country of birth) • Education • Income/poverty • Migration (Arrival in US, movement within US) • English speaking ability • Geospatial queries

  11. Migration • International Air Transport Association data obtained by BioDiaspora • License restrictions limit public use • Top US destinations receiving international arrivals • Sort to see which cities receive most people from particular countries

  12. Health • HealthMap events • Infectious disease events reported by WHO, ProMed, newspapers, user submissions • Updated every hour • Choose by disease, timeframe, data source • Geospatial queries • Other health data – Tuberculosis, obesity, etc.

  13. Use-Case Scenario
