Protecting public health was a core function of governments long before the expansion of the state in the 20th century. “Great fears of the sickenesses here in the City, it being said that two or three houses are already shut up,” Samuel Pepys wrote in his diary on April 16, 1665. “God preserve us all.” Londoners trying to flee the plague had to obtain a certificate of good health signed by the lord mayor, who also enforced a curfew and a lockdown of plague households. A generation after the Great Plague, Massachusetts was passing laws for the quarantining of smallpox patients.
Nineteenth century urban Britain experienced a huge rise in deaths from infectious diseases. In 1849, more than 50,000 people died from a cholera epidemic that swept London. The previous year, Parliament passed the landmark Public Health Act. According to historians of the act, “public health was not a party matter, nor was the need for comprehensive sanitary legislation controversial.” That year, the physician John Snow made the first great epidemiological breakthrough with his discovery that fecal contamination causes cholera.
A framework of public health law and improved medical knowledge led to the construction of vast networks of clean piped water, high-velocity sewers and recycling of waste. The Victorian sanitation revolution occurred during the zenith of classical liberalism, when public health was understood to mean measures that have to be applied to whole communities and not preventive activity, such as the campaign against the so-called epidemic of childhood obesity. A genuine pandemic, spreading geometrically across the globe in a matter of weeks, shows the phoniness of that “epidemic.”
