In 1795, the Scottish physician Alexander Gordon suggested that patients’ fevers were often the result of contagious processes and wrote that he believed that physicians (including himself) often carried this contagion to patients. Nearly 50 years later Sir Thomas Watson, a professor at King's College Hospital, London, who became president of the Royal College of Physicians, warned that colleagues who attended women with puerperal fever, a major cause of maternal mortality, were at risk for transmitting the disease to subsequent patients. He suggested that practitioners rinse hands with chlorine solution and change clothing following interactions with infected patients to avoid spreading puerperal fever from one patient to the next.
