New York City Hepatitis B and C Surveillance Case Counts

Case counts of newly reported Chronic Hepatitis B and C infections in New York City, based on legally mandated electronic laboratory reporting. The data undergoes automatic de-duplication to count only the first report per person. The NYC Health Department uses these data to monitor trends, prevent infections, and promote linkage to care.

Use Cases

• Analyze trends in newly reported Hepatitis B and C case counts over time to monitor public health outcomes.
• Investigate patterns in case reports after de-duplication based on name and date of birth to understand reporting volume.
• Support public health program evaluation by linking surveillance data to annual reports on infection trends and prevention efforts.

Strengths

• Data collection is legally mandated by NYC Health Code, ensuring consistent reporting from clinical laboratories.
• Includes automatic de-duplication methods to identify repeat reports and count unique individuals.

Limitations

• The specific number of rows, columns, and sample data are unavailable, limiting initial assessment of dataset scale and structure.
• Data is aggregated as case counts; individual-level clinical or demographic variables are not described.
