Between 1900 and 1917, hundreds of state and local TB associations sprung up across the United States. These associations distributed educational materials and provided financial support to sanatoriums and TB hospitals, where patients with active TB were isolated from the general population and, if lucky, could recover. In addition, these associations advocated, often successfully, for the passage of legislation designed to curb the transmission of TB, including requirements that doctors notify local public health officials about active TB cases.
Reporting requirements were a key feature of the campaign against TB. These requirements prevented physicians from concealing a diagnosis of TB from their patients and allowed local health officials to monitor TB patients, ensuring that they were taking precautions not to infect others.
In several states, “careless consumptives” could be forcibly committed to TB hospitals or sanatoriums, where they were not a threat to the health of their family and coworkers. When a TB patient died, municipalities and states often required that his or her premises be thoroughly disinfected. Although remarkable in its scope and intensity, the effectiveness of the U.S. TB movement has, to date, not been studied in a systematic fashion. Using municipal‐level data from 1900 to 1917 from Mortality Statistics, which was published on an annual basis by the U.S. Census Bureau, we estimate the relationship between pulmonary TB mortality and the introduction of public health measures designed to curb the spread of the disease.
Our estimates, which control flexibly for common shocks and municipal‐level heterogeneity, suggest that most anti‐TB measures had no discernable impact on pulmonary TB mortality. Two exceptions to this general result stand out: requiring TB cases to be reported to local health officials is associated with a 6 percent reduction in pulmonary TB mortality, and the opening of a state‐run sanatorium is associated with an almost 4 percent reduction in pulmonary TB mortality. These estimated effects are robust across a variety of specifications but can explain, at most, only a small portion of the overall decline in pulmonary TB mortality observed from 1900 to 1917.
