The Contagiousness of Puerperal Fever
Summary
The Contagiousness of Puerperal Fever is an essay that Oliver Wendell Holmes, then a young Boston physician, read to the Boston Society for Medical Improvement in 1843 and printed in a short-lived medical journal. Puerperal fever, or childbed fever, was an infection of the womb after childbirth that killed many mothers in the first days after delivery, sometimes in clusters around a single doctor or midwife. Holmes collected reports from Britain and America of physicians, nurses and midwives whose patients fell ill one after another while those of their neighbours escaped. One doctor lost several patients in a row after examining a woman who had died of the fever; another case followed a physician who had performed an autopsy and then gone directly to a delivery. Holmes argued that the disease was carried from patient to patient by the attendants themselves, on their hands and clothes. He did not know about bacteria, which were not yet understood as causes of disease, but he reasoned from the pattern of cases. The essay ends with practical rules: a physician who attends births should not take part in post-mortem examinations of fever victims; after a case of puerperal fever he should wash, change his clothes and wait before attending another birth; and a series of cases in one practice should be treated as a warning to stop. Holmes concluded that a 'private pestilence' in a single doctor's practice should be looked upon not as a misfortune but as a crime. Leading obstetricians in Philadelphia, especially Charles Meigs and Hugh Hodge, rejected the idea that gentlemen could carry disease. In 1855 Holmes reprinted the essay as a pamphlet with a sharp new introduction answering them. In Vienna, Ignaz Semmelweis reached a similar conclusion independently in 1847. Their argument was confirmed when Pasteur and others identified streptococcus bacteria in the fever.
Top Lessons
Arguing from patterns
Holmes had no microscope evidence, yet he built a convincing argument from the pattern of cases. Clusters around one attendant were hard to explain any other way.
Professional pride
Some leading doctors were offended by the suggestion that they carried disease. Holmes shows how pride can prevent people from accepting evidence that implicates themselves.
Duty to the vulnerable
Holmes insists that a doctor's duty to his patients outweighs his convenience or reputation. Women in childbirth had no way to protect themselves.
For the Christian reader
Holmes, a Unitarian, wrote as a moralist as well as a doctor. Scripture calls for care of the vulnerable and repentance when we harm others unknowingly; his essay asks professionals to examine their own hands before blaming fate.
