EXPLANATIONS BELOW
Concept note-1: -Epidemic typhus was widespread globally prior to the introduction of modern antibiotics. Outbreaks of louse-borne typhus occur during the colder months and have been associated with the overcrowded and unsanitary conditions that are prevalent in time of war. Epidemic typhus is rarely found among travellers.
Concept note-2: -In its early years, the Soviet Union paid great attention to the prevention of disease. Severe epidemics of infectious diseases such as typhus, cholera, smallpox, dysentery and malaria affected millions, with an estimated 6.5 million people contracting typhus in the period 1918–1920 alone (Glass, 1976).
Concept note-3: -Paleomicrobiology enabled the identification of the first outbreak of epidemic typhus in the 18th century in the context of a pan-European great war in the city of Douai, France, and supported the hypothesis that typhus was imported into Europe by Spanish soldiers returning from America.
Concept note-4: -Typhus was a major health problem in late nineteenth-and early twentieth-century Russia. Closely linked with poverty and overcrowded housing, this louse-borne disease was. endemic in both rural and urban areas, with scattered cases and small outbreaks occurring. every year, mostly in the winter and early spring.
