Epidemiologists use various methods to monitor infectious diseases, including:
Surveillance systems: Continuous collection, analysis, and interpretation of health-related data to plan, implement, and evaluate public health practices. Outbreak investigation: Identifying the cause, source, and spread of disease outbreaks to control and prevent further cases. Screening: Testing populations for infectious agents to identify and treat cases early. Contact tracing: Identifying and managing people who have been in contact with infected individuals to prevent further transmission.
