Diseases and Epidemics During Revolutionary America 1763 – 1783

Colonial physician

The Pennsylvania Hospital in Philadelphia compiled the most extensive report about diseases and success rates of doctors during the Revolutionary War Period. Aside from mental disorders which affected nearly one fifth of all patients, half of the hospital’s cases concerned seven disorders: scurvy – 15%, fevers – 9%, venereal disease – 9%, dropsy – 6%, eye disease – 4%, and respiratory – 4%. Despite limitations on 18th century medicine, 59% of all patients who were admitted to the hospital were cured and sent home. Another 11% had their symptoms relieved. Thirteen percent died under care. Cities suffered far more than rural areas. From 1768 – 1777, approximately every sixth Philadelphian, (4,175 residents), sought treatment at the Philadelphia Hospital.  Many, 65% of all cases, were handled as charity cases.

Epidemic diseases became an increasingly serious problem during the period of rebellion in America. New England had the country’s highest population density experiencing many outbreaks of diphtheria, scarlet fever, measles, and whooping cough. Adolescent mortality was heavily affected by these disorders and on rare occasions, farming communities were struck hard; such as Oxford, Massachusetts, where between 1766 and 1769, 10% of its community members died from diphtheria. Rural colonies in the mid-Atlantic experienced relatively few epidemics. The rural south was mostly spared from epidemics.

Smallpox Inoculation

Cities and urban centers did not fare so well as the countryside, poor sanitation and close proximity of dwellers allowed contagion to spread rapidly among the concentrated populations. Every decade saw smallpox outbreaks in most major cities and in many instances, claimed several hundred lives. The Continental Army was severely susceptible to smallpox because of its close proximity of its soldiers living quarters. Yellow fever, in which there was no medicinal cure, struck city centers hard, however, it did not raise its ugly head until the 1790’s.
