What's Happening?
New research has identified two diseases that contributed to the devastation of Napoleon's Grande Armée during its retreat from Moscow in 1812. Researchers analyzed DNA from the teeth of soldiers and discovered the presence of Salmonella enterica, responsible
for paratyphoid fever, and Borrelia recurrentis, which causes relapsing fever. These findings challenge the long-held belief that typhus was the primary disease affecting the army. The study, published in Current Biology, highlights the role of poor sanitary conditions in the spread of these diseases. The research provides a clearer understanding of the health challenges faced by Napoleon's troops, who suffered from fatigue, cold, and multiple infections.
Why It's Important?
The study offers new insights into historical epidemiology and the impact of infectious diseases on military campaigns. Understanding the pathogens that affected Napoleon's army can inform modern public health strategies, particularly in managing outbreaks in conditions of poor sanitation. The research underscores the importance of hygiene and disease prevention in military and civilian settings. By identifying previously undocumented pathogens, the study also advances the field of microbial paleogenomics, providing a more comprehensive picture of historical disease dynamics.
