Surveillance is the process of monitoring health data. It helps track diseases in populations. This information guides public health actions. Surveillance can be active or passive.
Active Surveillance
Active surveillance means health workers collect data. They reach out to hospitals and clinics. They ask about disease cases. This method provides current data. It helps find outbreaks quickly.
Passive Surveillance
Passive surveillance relies on reports. Doctors and hospitals send reports to health departments. This method is less intensive. However, it may miss some cases. It is still important for understanding health trends.
Importance of Surveillance in Public Health

Health Records
Health records provide valuable information. Doctors keep records of patients’ health. This data helps track diseases and treatments.
Laboratory Testing
Laboratories test samples for diseases. They provide important data to health officials. Testing helps confirm outbreaks and find new cases.
Challenges in Public Health Surveillance
Public health surveillance faces many challenges. Some of these challenges include:
- Limited resources
- Lack of trained personnel
- Privacy concerns
