- Surveillance Systems: Such as the CDC's National Notifiable Diseases Surveillance System (NNDSS). - Health Surveys: Like the National Health and Nutrition Examination Survey (NHANES). - Electronic Health Records (EHRs): Data from hospitals and clinics. - Registries: Cancer registries, birth and death registries. - Laboratory Reports: Data from diagnostic labs.
