What Is Childbed Fever? The History of Puerperal Fever

Childbed fever, medically known as puerperal fever, was a devastating historical illness that struck women immediately following childbirth or miscarriage. This serious bacterial infection of the female reproductive tract turned delivery into a life-threatening gamble for centuries. It became a major contributor to maternal death, particularly after the rise of centralized hospital care in the 18th and 19th centuries. Understanding its conquest marks a significant chapter in the history of medicine, illustrating the profound impact of infection control.

Defining Puerperal Fever

Puerperal fever is defined as an acute, systemic infection that affects the genital tract during the postpartum period. The infection typically begins in the lining of the uterus (endometrium) but can rapidly spread throughout the body, causing severe sepsis. Symptoms usually appear after the first 24 hours following delivery and within the first ten days postpartum. A defining sign is a recurring or sustained fever exceeding 38.0 °C (100.4 °F).

This fever is often accompanied by intense chills, malaise, and severe lower abdominal pain. An odorous vaginal discharge is also a common symptom. Before modern treatment, the rapid progression of the infection from the uterus into the bloodstream often led to peritonitis (inflammation of the abdominal lining) and ultimately death.

The Historical Mystery and Cause

For centuries, childbed fever was an inexplicable scourge in maternity wards, often reaching epidemic proportions. In the 18th and 19th centuries, mortality rates in some European hospitals could soar, sometimes claiming the lives of 20 to 40 percent of admitted women. Lacking an understanding of microbiology, medical professionals proposed theories like environmental factors or “miasmas” (foul-smelling vapors). The disease was considered an unavoidable consequence of hospital birth, leading many women to prefer delivering at home with midwives.

The true cause was bacterial, primarily Streptococcus pyogenes (Group A Strep), transmitted inadvertently during delivery or examination. The most tragic source of contamination was the medical staff themselves, who frequently moved directly from performing autopsies or treating sick patients to maternity wards without cleaning their hands. The bacteria were introduced into the vulnerable surface of the uterus where the placenta had detached. This practice created a deadly pathway for infection, turning hospitals into centers of contagion.

The Triumph of Hygiene and Modern Prevention

The turning point in the history of childbed fever is attributed to the observations of Hungarian physician Ignaz Semmelweis in the mid-19th century. Working in the Vienna General Hospital, Semmelweis noted a dramatic difference in mortality rates between two maternity clinics: the one staffed by physicians had a death rate multiple times higher than the one staffed by midwives. He hypothesized that “cadaverous particles” from the autopsy room were the source of the infection. In 1847, Semmelweis mandated that all medical staff wash their hands with a chlorinated lime solution before examining patients.

The results were immediate; the maternal mortality rate in his division plummeted from approximately 18 percent to under 2 percent within months. Although his findings were initially met with skepticism because germ theory was not yet established, his work provided the first empirical evidence of the disease’s contagious nature and the power of simple hygiene. Later, the acceptance of germ theory, driven by Louis Pasteur, led to the adoption of antiseptic techniques in surgery and obstetrics. Joseph Lister further solidified the use of instrument sterilization and aseptic practices, effectively eliminating historical childbed fever as a common killer in developed nations.

Puerperal Sepsis Today

The historical term “childbed fever” has been replaced by the clinical diagnosis of Puerperal Sepsis or Maternal Sepsis. Thanks to robust infection control and the use of antibiotics, this condition is now rare in developed countries, yet it remains a substantial cause of maternal mortality worldwide. The infection results from bacteria entering the genital tract through wounds created during delivery, such as C-section incisions or tears. Risk factors that increase susceptibility include:

  • Cesarean delivery.
  • Prolonged labor.
  • The presence of retained placental fragments.
  • Multiple vaginal examinations during labor.

When Puerperal Sepsis is diagnosed today, treatment requires immediate and aggressive intervention to prevent the infection from overwhelming the body. The standard of care involves the swift administration of broad-spectrum antibiotics, often given intravenously. Supportive measures, such as fluid management and close monitoring, are also employed to stabilize the patient. While epidemic childbed fever is part of history, continuous vigilance and adherence to modern hygiene protocols remain necessary to manage this persistent, potentially fatal postpartum infection.
