All states are participating in national morbidity reporting by 1925. This weekly report is a public health requirement, tracking everything from lead in drinking water to asthma rates. Tensions arise between doctors and public health leaders over patient privacy, and will continue until the 1960s, when standardized patient tracking becomes the norm.

The report will go on to enable the discovery of AIDS. It will also be used by state agencies for eugenics strategies, such as forced sterilization, institutionalization, and, more recently, deportation.
