[The black death in Christian and Muslim Occident, 1347-1353].

Between the years 1346 and 1353, a terrible epidemic swept over Western Asia, the Middle East, Africa, and Europe, causing catastrophic losses of population everywhere, both in the rural areas and in towns and cities. The Black Death was a disease of such magnitude that it not only shook the Old World to its economic and social foundations but changed the course of human history. The authors considered and analyzed many studies on the Black Death published in different languages. In the present paper they report medical and epidemiological specificities of the pandemic as well as its geographical origins and the routes of its spread.
