This month in History saw the birth of modern epidemiological surveillance:
August 30, 1889: The Infectious Disease Notification Act received Royal Assent in the United Kingdom. This groundbreaking public health law introduced compulsory notification of infectious diseases. It required heads of households and attending doctors to report outbreaks to local medical officers, giving authorities an early warning system to outbreaks of disease and facilitate rapid intervention. This act allowed authorities to track and quarantine affected households and institutions and mandate disinfection of properties and contaminated belongings.
This legislation was incredibly successful in controlling outbreaks and formed the structural blueprint for modern public health laws worldwide. Today, these are used to track outbreaks of diseases such as COVID-19, measles and most recently, the Cyclospora outbreak in the USA.
