Abstract
In the late 1930s, states began to pass laws requiring men and women applying for marriage licences to demonstrate proof of a blood test showing that they did not harbour communicable syphilis. Advocates of the laws positioned marriage as a public health checkpoint to identify new cases of syphilis as part of a broader effort to approach the disease as a public health problem, rather than a moral one. Although the laws appeared to have broad popular support, in reality they were a failed public health intervention. Couples rushed to the altar before laws went into effect and border-hopped to marry in states without blood test laws. The blood tests used to detect syphilis were difficult to interpret and physicians could not agree on a standard definition of communicable disease. But for over 30 years, premarital examination laws represented a tangible government presence in the private lives of most Americans.
