The basis of the modern medical hygiene in the medieval Medical School of Salerno

The link between hygiene and the concept of transmission of infective diseases was established earlier than the birth of microbiology, thanks to the studies of two neglected physicians of maternity clinic, Ignac Fulop Semmelweis and Oliver Holmes, in the mid-1800s. Surprisingly, centuries earlier, a medieval women physician, Trotula de Ruggiero, introduced for the first time the notion of diseases' prevention, highlighting the importance of the association of personal hygiene, balanced nutrition and physical activity for better health. Moreover, she was particularly concerned of hands hygiene for the midwives during child birth, to preserve the good health of both the mother and the baby. She practiced inside the medieval Medical School of Salerno, whose main text, the "Regimen Sanitatis Salerni" has an entire part dedicated to hygiene, providing hygienic precepts that anticipate the concepts derived from the revolutionary discoveries in medical science only centuries later.
