Public Health Progress
• It is nearly impossible to spend a single day in the US without being
affected by public health – consider these daily life examples:
• food safety
• restaurant inspections
• fluoridated water
• seatbelt use
• unleaded gasoline
• influenza vaccine programs
• trans-fats and other nutritional information
• public health response to the most recent disaster
• Public health in the US has a long record of working in the public
interest; that record is almost entirely positive

A Terrible Injustice
•
A terrible episode mars the otherwise favorable record of public health in the
US
•
The Public Health Service was one of several sponsors of two related and
horrific studies (physician John Cutler was involved in both studies):
– 1932 – Public Health Service began the infamous Tuskegee Study
which recorded effects of syphilis on black men. Even after penicillin
became the recommended drug treatment in 1947, the men did not
receive adequate treatment. In 1972, an advisory panel found the study
"ethically unjustified” and it was immediately halted
– 1940’s – Experiment which deliberately sought to infect inmates at the
Guatemalan National Penitentiary with syphilis in order to study the
effects of early penicillin treatment
•
Public Health has worked tirelessly to improve population health. While the
injustice of these studies must be both noted and remembered, it is
important to also remember the enormous benefits that Public Health has
conferred
