The response to the trench diseases in World War I: a triumph of public health science

The recent 90-year anniversary of the Battle of the Somme presents an opportunity to examine the public health response to the trench diseases, new conditions which arose in the trenches of World War I. Throughout history, there have been two views of epidemic disease: the configurationist and contagionist perspectives. Most doctors responding to the trench diseases, 'contingent-contagionists', combined these two conceptions of disease. Because of the difficulty of finding a causative organism and the absence of effective treatment, the majority view became that these conditions were a product of the trench environment. Configurationism, with its emphasis on environmental and social determinants, seemed to provide the most obvious approaches for tackling the trench diseases. The diseases were effectively controlled using the tools of public health science: sanitary discipline and a battery of measures, such as improving trench construction, improving the diet, providing protective kit, regular bathing and treating lice infestation. The response demonstrates the triumph of public health science over new medical technologies. It also illustrates the importance of considering all the many determinants of health and of close surveillance, discipline and partnership working to counter ill-health. Although technology, training, doctrine and health beliefs change over time, the interaction between disease and environment remains the core challenge to public health practitioners.

Evidence for louse-transmitted diseases in soldiers of Napoleon's Grand Army in Vilnius

BACKGROUND

Many soldiers in Napoleon's Grand Army died of infectious diseases during its retreat from Russia. Because soldiers were commonly infested with body lice, it has been speculated that louse-borne infectious diseases, such as epidemic typhus (caused by Rickettsia prowazekii), were common.

METHODS

We investigated this possibility during recent excavations of a mass grave of Napoleon's soldiers in Vilnius, Lithuania. Segments of 5 body lice, identified morphologically and by polymerase chain reaction (PCR) amplification and sequencing, were found in earth from the grave that also contained fragments of soldiers' uniforms.

RESULTS

DNA of Bartonella quintana (the agent of trench fever) was identified by PCR and sequencing in 3 of the lice. Similarly, PCR and sequencing of dental pulp from the remains of 35 soldiers revealed DNA of B. quintana in 7 soldiers and DNA of R. prowazekii in 3 other soldiers.

CONCLUSIONS

Our results show that louse-borne infectious diseases affected nearly one-third of Napoleon's soldiers buried in Vilnius and indicate that these diseases might have been a major factor in the French retreat from Russia.

Trench fever in Belfast, and the nature of the 'relapsing fevers' in the United Kingdom in the nineteenth century

Some evidence is assembled to suggest that trench fever, an infection with a strain of Rochalimaea, if not quintana, then vinsonii, was present in Belfast in the first half of the nineteenth century in endemic and epidemic form. It may have amounted at times to one half or more of 'fever'. This may account for the comparatively low mortality in some years from 'fever'. The phrase 'relapsing fever' in the nineteenth and twentieth century medical literature of the United Kingdom should not be taken necessarily to mean infection with Borrelia recurrentis. Much or most may have been infection with Rochalimaea, quintana or vinsonii. The newly discovered Irish vole should be examined to see if it carries a Rickettsia or Rochalimaea infection.
