Surfing on the web I found a description of the organisation of the medical services in France during WW1. It gives also a description of the different diseases, medicaments and the medical help to avoid them. There are a few nice photo's, maybe intresting for those who want to make a diorama places somewhere behind frontline (shower card, desinfection card, water purification card,...) All text is in French and it is the Thesis from Mr Levy Christophe (Medical student).
Marvellous find, thanks for the link and the pictures - part of the steady progress of medicine and field hygiene. A critically important aspect of modern warfare - as is readily apparent in reviewing the casualty details of the wars of a century before, and even later, when disease alone might account for many times the losses and incapacitation caused by direct military actions. Not that hygiene in the WW1 trenches was anything to greatly praise but those circumstances were sometimes impossible.
