  3. Definitions • Public health surveillance is the systematic, ongoing collection, management, analysis, and interpretation of data followed by the dissemination of these data to public health programs to stimulate public health action • Source: Thacker

  4. Definitions • Passive surveillance: a system by which a health jurisdiction receives reports submitted from hospitals, clinics, public health units • Active surveillance: a system employing staff members to regularly contact heath care providers or the population to seek information about health conditions. • Syndromic surveillance: an active or passive system that uses case definitions that are based entirely on clinical features without any clinical or laboratory diagnosis • Behavioral risk factor surveillance system (BRFSS): an active system of repeated surveys that measure behaviors that are known to cause disease or injury Source: DCP2

  5. Content • Definitions and lexicon • History of surveillance • Conceptual framework • IHR 2005 • The case of PHS in Mexico • New tools for rapid detection • Questions for discussion

  6. History of PHS • England--John Graunt and William Petty (XVII Century) • France—Comites de SantePublique • USA—in 1741, the colony passed an act requiring tavern keepers to report contagious diseases among their patrons. Two years later, the colony passed a broader law requiring the reporting of smallpox, yellow fever, and cholera • In 1893, Michigan became the first jurisdiction to require the reporting of specific infectious diseases. Also in 1893, a law was enacted to provide for collecting information each week from state and municipal authorities throughout the United States.

  7. History of PHS • In 1951, Langmuir established the Epidemic Intelligence Service (EIS), which provided a unique approach to training men and women in applied epidemiology. • The program has trained approximately 3,000 epidemiologists during the past six decades in the principles and practice of public health surveillance. • It is now emulated as Field Epidemiology Training Programs in approximately 30 countries around the world Source: Thacker

  11. Disclosure: Some of my comments here are based on a Paper prepared for the 1992 International Symposium on Public Health Surveillance, Carter Center, Atlanta, April 22-24, 1992 “Key issues in Public Health Surveillance for the 1990”s” Authors: Sepulveda, Frenk, Gomez de Leon et al

  12. Six PHS needs “To advance public health surveillance in the 21st century, at least six major concerns must be addressed by the public health community: • a common lexicon; • global surveillance needs; • informatics, including information technology; • a skilled workforce; • data access and use; • and data management, storage and analysis. “ Source: Thacker MMWR 2012
