OR:

The history of public health in the United states studies the US history of public health roles of the medical and nursing professions; scientific research; municipal sanitation; the agencies of local, state and federal governments; and private philanthropy. It looks at pandemics and epidemics and relevant responses with special attention to age, gender and race. It covers the main developments from the colonial era to the early 21st century. At critical points in American history the public health movement focused on different priorities. When epidemics or pandemics took place the movement focused on minimizing the disaster, as well as sponsoring long-term statistical and scientific research into finding ways to cure or prevent such dangerous diseases as

in the late 19th century caused a shift in perspective. Instead of attributing disease to personal failings or God's will, reformers focused on removing threats in the environment. Special emphasis was given to expensive sanitation programs to remove masses of dirt, dung and outhouse production from the fast-growing cities or (after1900) mosquitos in rural areas. Public health reformers before 1900 took the lead in expanding the scope, powers and financing of. local governments, with New York City and Boston providing the models. Since the 1880s there has been an emphasis on laboratory science and training professional medical and nursing personnel to handle public health roles, and setting up city, state and federal agencies. The 20th century saw efforts to reach out widely to convince citizens to support public health initiatives and replace old folk remedies. Starting in the 1960s popular

led to an urgency in removing pollutants like DDT or harmful chemicals from the water and the air, and from cigarettes. A high priority for social reformers was to obtain federal health insurance despite the strong opposition of the American Medical Association and the insurance industry. After 1970 public health causes were no longer deeply rooted in liberal political movements. Leadership came more from scientists rather than social reformers. Activists now focused less on the government and less on infectious disease. They concentrated on chronic illness and the necessity of individuals to reform their personal behavior—especially to stop smoking and watch the diet—in order. to avoid cancer and heart problems.Paul Starr, ''The social transformation of American medicine: The rise of a sovereign profession and the making of a vast industry'' (Basic, 1983). 379–419.

. Localistic community-oriented care was typical, with families and neighbors providing assistance to the sick using traditional remedies and herbs. New immigrants to the colonies had high death rates from their exposure to a new disease environment. However by the second generation death rates were lower than in England because there was much more food and less crowding. Becoming a regular doctor was difficult. Finally in 1765 the first medical school opened at the College of Philadelphia. That city opened a hospital in 1751; the second one opened in New York City in 1791. By 1775 the 13 colonies had 3,500 to 4,000 regular doctors. About one in ten was formally trained, usually in England or Scotland. They had a clientele among the wealthier classes, but the popular image was one of distrust.

—experienced high mortality rates, particularly among new arrivals from England. This high death rate significantly impacted family structures and slowed population growth. Men immigrated far more than women, so there was a persistent shortage of females in the Chesapeake colonies, which further stifled natural population increase and lowered rates of marriage for men. Due to the high mortality rates and unbalanced sex ratio, traditional family structures were difficult to maintain. Many families consisted of step-parents, step-children, and half-siblings, creating complex family networks. By contrast, New England had lower death rates, and much more family stability, and enabled the patriarchal New Englanders to better make long-term plans for acquiring enough land to provide farms for the next generation.

In the 1775–1782 North American smallpox epidemic data based on remnant settlements indicate at least 130,000 people died in the epidemic that started in 1775. During the Revolution General George Washington insisted his soldiers get inoculated else his forces might get decimated or the British try to use smallpox as a weapon.


The New Nation to 1900


Statistics and sanitation

Lemuel Shattuck Lemuel Shattuck (15 October 1793, in Ashby, Massachusetts – 17 January 1859, in Boston, Massachusetts) was an American educator, politician, historian, bookseller, and publisher. He is best known for promoting statistical studies of population ...
(1793-1859) of Boston promoted legislation that required a better statewide system for the local registration of vital information on births and deaths. He specified the need for precise details on age, sex, race, and occupation, as well as standard terminology for diseases and cause of death. This law was passed in 1842 and was soon copied by most other states. His proposals greatly expanded the questionnaires used in the Massachusetts state census of 1845. He was a key consultant for the 1850 United States census. He helped convince Congress to fund a much more complex census, and he designed most of the interview forms used by door-to-door canvassers. His ''Report on the Sanitary Condition of Massachusetts'' in 1850 on a sanitary survey of Massachusetts was farsighted. It explained how to remove the giant mounds of dirt, horse dung, and outhouse production that were overwhelming the neighborhoods of fast growing cities. It inspired reforms in many cities that faced the same public health crisis.


Metropolitan Board of Health in New York City

Metropolitan Board of Health The New York City Metropolitan Board of Health was the first modern municipal public health authority in the United States. It was founded in 1866 by the New York City Common Council at a suggestion by the New York Academy of Medicine, following a c ...

who controlled the New York state legislature. It became a model for many major cities due to its innovative approach and effectiveness in addressing public health issues. The state government gave the city's Board extensive powers to create, execute, and judge ordinances related to public health. This comprehensive authority allowed for swift and effective action in addressing health crises. The Board leadership consisted of four police commissioners, the health officer of the Port of New York, and four commissioners appointed by the governor, three of whom were required to be physicians. This diverse makeup ensured a balance of expertise and perspectives. Within weeks of its formation, the Board secured agreements with city butchers to clean up and relocate slaughterhouses, imposed health standards on the milk industry, improved water supply, and began cleaning city streets. When the cholera epidemic broke out in the spring of 1866, the Board successfully fought it with a stringent health code, house-to-house inspections, disinfectants, and quarantines. This resulted in a significantly lower death toll in New York City compared to other major cities. The Board's formation was preceded by a comprehensive sanitary inspection of New York City, which revealed widespread poor living conditions in the slum districts. This data-driven approach to identifying and addressing public health issues was modelled after Shattuck's statewide work in Massachusetts. It became a standard practice in other cities. Furthermore, the Board recognized the connection between housing, politics, morals, and health, setting a precedent for addressing the social determinants of health. The success of New York City's Metropolitan Board of Health in improving public health conditions and managing disease outbreaks demonstrated the effectiveness of a centralized, empowered health authority. This model was subsequently adopted by other cities and states, shaping the future of public health administration in America.

opened in 1782; Dartmouth in 1797; Yale in 1810. According to Kenneth Ludmerer and William G. Rothstein American medical schools before 1880 had far more weaknesses than strengths. There were no entrance requirements—any young man could sign up and many schools did not even require a high school diploma. The curriculum was narrow, consisting of only seven courses, and instruction was entirely didactic lectures with little to no practical experience, no laboratories, and no work with patients. Physical facilities were meager, often just a single amphitheater or the second floor. Most schools were proprietary, operated for profit by their faculty, who gave most of their attention to their private practice. The standard course consisted of only two four-month terms of lectures. Graduation requirements were minimal, with brief and superficial examinations. The strengths were that the many proprietary schools made a professional career more widely available than the colonial apprenticeship system it replaced. Furthermore the lectures provided more systematic teaching compared to the apprenticeship model After 1880 German medical influences modernized the system with leaders like Johns Hopkins, Harvard, Pennsylvania, Columbia and Michigan extending their courses, adding new scientific subjects, and hiring full-time medical scientists with laboratories.


Hospitals

Hospitals in the 19th century were largely designed for poor people in the larger cities. There were no paying patients. Very small proprietary hospitals were operated by practicing physicians and surgeons to take care of their own paying patients in better facilities than the charity hospitals offered. By the 1840s, the major religious denominations, especially the Catholics and Methodists, began opening hospitals in major cities. The South had small hospitals in its few cities. In the rich plantation areas, slave owners hired physicians to keep their slaves in working shape. In the poor white areas there were few doctors and very few hospitals. In the 1840s–1880s era, Catholics in Philadelphia founded two hospitals, for the Irish and German Catholic immigrants. They depended on revenues from the paying sick, and became important health and welfare institutions in the Catholic community. By 1900 the Catholics had set up hospitals in most major cities. In New York the Dominicans, Franciscans, Sisters of Charity, and other orders set up hospitals to care primarily for their own ethnic group. By the 1920s they were serving everyone in the neighborhood. In smaller cities too the Catholics set up hospitals, such as St. Patrick Hospital in

The nuns provided nursing care especially for infectious diseases and traumatic injuries. They also proselytized the patients to attract converts and restore lapsed Catholics back into the Church. They built a larger hospital in 1890. Catholic hospitals were largely owned and staffed by orders of nuns (who took oaths of poverty), as well as unpaid nursing students. When the population of nuns dropped sharply after the 1960s, the hospitals were sold. The Catholic Hospital Association formed in 1915. The

The South

Compared to the North and West, the South was always a warmer climate that fostered diseases. It had far fewer cities and they lagged the North in innovation. After the Civil War it was a much more sickly region, lacking in doctors, hospitals, medicine, and all aspects of public health. When a threat of yellow fever appeared Southern cities imposed temporary quarantines to stop travel from infected areas. The rest of the time there was inaction, and a reluctance to spend on sanitation. Most Southerners were too poor to buy the patent medicines that were so popular elsewhere. Instead there was a heavy reliance on cheap herbal and folk remedies, especially among African Americans and Appalachians.

, historically were rural phenomenon in warm areas of the South. They were stamped out by large-scale efforts to clean up the environment. Malaria is spread by the bite of a particular species of mosquito, and is eradicated by systematically draining pools of stagnant water or spraying with DDT. The Rockefeller Sanitary Commission in 1910 discovered that nearly half the farm people, white and Black, in the poorest parts of the South were infected with hookworms. In the typical victim hundreds of the worms live hooked to the wall inside the small intestine, eat the best food, and leave the victim weak and listless. It was called the "germ of laziness." Victims were infected by walking barefoot in grassy areas where people defecate. In the long run outhouses and shoes solved the problem but the Commission developed a quick cure. The volunteer drank a special medicine that loosened the insects' grip, then drank a strong laxative. When most residents did so the hookworms would be gone. The Commission, headed by

The Black South

In the Southern states 1890s to 1930s, Jim Crow virtually dictated inferior medical care for the large, very poor African American minority. There was neglect and racism on the part of white physicians. Black physicians were too few and too poorly trained at their two small schools,

They were not asked to give permission, were not told their medical condition, and when penicillin became available in the mid 1940s it was deliberately not given them so the researchers could discover what happens to untreated men. As a result the lives of 100 of the 399 men were cut short and they died of syphilis. In retrospect the Tuskegee experiment caused deep distrust on the part of the African American community, and apparently reduced Black reliance on public health agencies. One research study in 2018 estimated that the angry negative response caused the average life expectancy at age 45 for all Black men to fall by up to 1.5 years.


Since 1900

Before the measles vaccination program started in 1963, an estimated 3 to 4 million people got measles each year in the United States, of which 500,000 were reported. Among reported cases, 400 to 500 died, 48,000 were hospitalized, and 1,000 developed encephalitis (brain swelling) from measles.
Measles affected approximately 3,000 Americans per million until the 1960s. The first effective vaccine appeared in 1963, and was quickly adopted with little controversy. The rate plunged to 13 cases per million by the 1980s, and to about 1 case per million by 2000. In the 21st century occasional measles, outbreaks occur locally, usually caused by a person returning from a foreign visit. The disease is highly contagious, but with a community vaccination rate of 95% or higher, a local outbreak will quickly end. With lower rates of vaccination, however, measles can continue to spread.

1917 Measles in the Army

When the U.S. Army began drafting 4 million soldiers in 1917–1918, 95,000 men who had never been exposed to measles before caught the disease. Of these, 23,000 were hospitalized and 3,206 died. Most of the victims came from rural areas where measles was uncommon. There was simultaneously a parallel epidemic of primary streptococcal pneumonia in soldiers without measles.

Tuberculosis

In the United States there was dramatic reduction in what had been the greatest killer, tuberculosis (often called "consumption"). Starting in the 1900s, public health campaigns were launched to educate people about the contagion. In later decades, posters, pamphlets and newspapers continued to inform people about the risk of contagion and methods to avoid it, including increasing public awareness about the importance of good hygiene and avoidance of spitting in public.

Children

Public health programs have significantly improved children's health over the past century through various initiatives and interventions. These programs have addressed key issues such as infant mortality, disease prevention, and access to local healthcare for mothers and their babies. By 1915 child health had become a priority.

, founded in 1912, played a crucial role in improving children's health. Congress originally gave it a very broad mandate:
The said bureau shall investigate and report ...upon all matters pertaining to the welfare of children and child life among all classes of our people, and shall especially investigate the questions of infant mortality, the birth-rate, orphanage, juvenile courts, desertion, dangerous occupations, accidents and diseases of children, employment, legislation affecting children in the several states and territories.
Its actual work was much more limited. Its major initiatives included the Campaign for Better Babies (1915), to educate mothers, reduce infant mortality, and identify threats to children's health. The Children's Year (1918-1919) promoted child health and welfare, focusing on reducing infant mortality, improving nutrition, and promoting safe recreation. The Sheppard–Towner Act of 1921 had a significant influence on children's health policies, marking a turning point in public health initiatives for mothers and infants. It set the stage for future federal involvement in maternal and child health care. It set up 3,000 child and maternal health care centers, many in rural areas. It funded millions of home visits by nurses to mothers and their infants. One result was the infant mortality rate dropped from 76 deaths per 1000 live births to 68 in 1929. Title V of the Social Security Act (1935) established a federal-state partnership for maternal and child health services, providing funding for state health departments to implement children's health programs. The 1950s and 1960s saw major efforts to vaccinate children against various diseases, especially polio. In 1971 the

s became available. They were quick, cheap cures for many of the most common and deadly bacterial infections, including tuberculosis and pneumonia. They extended the average human lifespan by 23 years and marked a "Golden Age" of public health. The 1950s and 1960s saw the advent of other powerful drugs: medicines to prevent inflammation in the joints and kidneys; to dilate arteries in the battle against high blood pressure or constrict blood vessels to combat shock; to regulate heartbeats; and to thin the blood. Professional medicine now for the first time was armed with drugs to cure major diseases. Diseases caused by a virus, however, were still not curable, and the new problem emerged of new variants of bacteria that resisted the new drugs.

(1803-1887) were instrumental in shifting societal perceptions of mental health and advocating for humane care. In three years in the mid 1840s she traveled more than 10,000 miles by stagecoach, visiting over 500 almshouses, 300 county jails, 18 state penitentiaries, and an indeterminate number of hospitals. In 1843, she submitted a "Memorial" to the Legislature of Massachusetts, describing the abusive treatment and horrible conditions received by the mentally ill patients in jails, cages, and almshouses. "I proceed, gentlemen, briefly to call your attention to the present state of insane persons confined within this Commonwealth, in cages, closets, cellars, stalls, pens! Chained, naked, beaten with rods, and lashed into obedience...." She made similar studies for other states and reported to their legislatures. Her activism led to 32 new hospitals and a nationwide reform of the asylum system, funded by state governments. Dix's work helped change public attitudes toward mental illness. She convinced state leaders that individuals with mental health conditions deserved humane treatment and that society had a responsibility to care for its most vulnerable members.


Mental hygiene movement

In ''A Mind That Found Itself'' (1908) Clifford Whittingham Beers described the humiliating treatment he received and the deplorable conditions in the mental hospital. In 1909, the National Committee for Mental Hygiene (NCMH) was founded by Beers and a small group of reform-minded scholars and scientists. Beers explained, “Its chief concern was to humanize the care of the insane: to eradicate the abuses, brutalities and neglect from which the mentally sick have traditionally suffered.” It marked the beginning of the "mental hygiene" movement. The NCMH (later Mental Health America) played a pivotal role in promoting education, prevention, and scientific approaches to mental health care,

catalyzed this idea with an additional emphasis on the impact of maladjustment, which convinced the hygienists that prevention was the only practical approach to handle mental health issues. However, prevention was not always successful, especially for chronic illness; the condemnable conditions in the hospitals were even more prevalent, especially under the pressure of the increasing number of chronically ill and the influence of the depression.


Deinstitutionalization

In 1961, the Joint Commission on Mental Health published a report called Action for Mental Health, whose goal was for community clinic care to take on the burden of prevention and early intervention of the mental illness, therefore to leave space in the hospitals for severe and chronic patients. The court started to rule in favor of the patients' will on whether they should be forced to treatment. By 1977, 650 community mental health centers were built to cover 43 percent of the population and serve 1.9 million individuals a year, and the lengths of treatment decreased from 6 months to only 23 days. However, issues still existed. Due to inflation, especially in the 1970s, the community nursing homes received less money to support the care and treatment provided. Fewer than half of the planned centers were created, and new methods did not fully replace the old approaches to carry out its full capacity of treating power. Besides, the community helping system was not fully established to support the patients' housing, vocational opportunities, income supports, and other benefits. Many patients returned to

(NIMH) in 1975 created the Community Support Program (CSP) to provide funds for communities to set up a comprehensive mental health service and supports to help the mentally ill patients integrate successfully in the society. The program stressed the importance of other supports in addition to medical care, including housing, living expenses, employment, transportation, and education; and set up new national priority for people with serious mental disorders. In addition, the Congress enacted the

to prioritize the service to the mentally ill and emphasize the expansion of services beyond just clinical care alone. Later in the 1980s, under the influence from the Congress and the Supreme Court, many programs started to help the patients regain their benefits. A new Medicaid service was also established to serve people who were diagnosed with a "chronic mental illness". People who were temporally hospitalized were also provided aid and care and a pre-release program was created to enable people to apply for reinstatement prior to discharge. Not until 1990, around 35 years after the start of the deinstitutionalization, did the first state hospital begin to close. The number of hospitals dropped from around 300 by over 40 in the 1990s, and finally a Report on Mental Health showed the efficacy of mental health treatment, giving a range of treatments available for patients to choose. However, several critics maintain that deinstitutionalization has, from a mental health point of view, been a thoroughgoing failure. The seriously mentally ill are either homeless, or in prison; in either case (especially the latter), they are getting little or no mental health care. This failure is attributed to a number of reasons over which there is some degree of contention, although there is general agreement that community support programs have been ineffective at best, due to a lack of funding. The 2011 National Prevention Strategy included mental and emotional well-being, with recommendations including better parenting and early intervention programs, which increase the likelihood of prevention programs being included in future US mental health policies.

Life Expectancy

in the United States has shown a remarkable increase over the past century, with a few small fluctuations. In 1900, life expectancy at birth was approximately 47 years. This figure rose steadily, reaching about 69 years by 1950; 72 in 1975, and 77 in 2000 . In 2023 it reached 78.4 years—75.8 years for males and 81.1 years for females.

became leading causes of death. * Race: In 1900 life expectancy at birth was 47.6 years for white babies and 33.0 years for Blacks. In 1970 it was 71.7 and 65.3. As of 2021, life expectancy at birth varies significantly by race and ethnicity: **Asian Americans: 84 years **Hispanic Americans: 78 years **White Americans: 76 years **Black Americans: 71 years **Native Americans: 65 years * Public Health Measures: Improvements in sanitation, nutrition, medical care, drugs, technology, and awareness of risk have contributed to the overall increase in life expectancy. Mortality rates in major cities fell sharply from 1900 to 1930s. According to Cutler and Miller, the main factor was cleaning up the water supply through filtration and chlorination. They estimate that this accounted for nearly half of the total mortality reduction. The greatest impact was on young people, in terms of 3/4 of the reduction in infant mortality and nearly 2/3 for child mortality.
