In the June 2020 issue of Significance, we tell the story of medical researchers in the late nineteenth century, some of whom went to extreme lengths to identify the transmission mechanism of yellow fever, a killer disease.

However, with respect to informed consent, their practices were, by the standards of the time, quite advanced, as we will explain here.

NHS England, in giving the name “Nightingale Hospital” to seven temporary hospitals for Covid-19 patients, is recognizing Nightingale’s relevance to combatting infectious diseases.
