Traceability in epidemiology is achieved through various methods:
Contact tracing: This involves identifying and following up with individuals who have come into contact with an infected person. Surveillance systems: These systems collect and analyze data on disease occurrence and spread. Genomic sequencing: This helps in identifying the genetic makeup of pathogens, allowing for the tracking of specific strains. Epidemiological studies: These studies investigate the distribution and determinants of health-related events in populations.
