Tracking Influenza Cases and Preventive Measures

Background

Public health surveillance is the ongoing process for systematically collecting, analyzing, and interpreting health-related data. These data are needed for planning, implementing, and evaluating public health practice. Surveillance results are shared in a timely manner with those who prevent and control health and safety risks.

The influenza surveillance activities of the National Institute for Occupational Safety and Health (NIOSH) fit into the bigger picture of Centers for Disease Control and Prevention (CDC) influenza surveillance activities. This work monitors disease burden; virus characteristics; vaccine or antivirals availability, use, and adverse events; medical care or infrastructure; school and workforce protection, and other non-pharmaceutical interventions.

CDC divides influenza disease surveillance into five categories, described on the Overview of Influenza Surveillance in the United States:

  • Viral Surveillance
  • Outpatient Illness Surveillance
  • Mortality Surveillance
  • Hospitalization Surveillance
  • Summary of the Geographic Spread of Influenza

NIOSH tracks workplace factors that affect influenza activity by incorporating occupational information into broad influenza surveillance systems developed and maintained by other CDC centers.
