Practice Relating to Rule 26. Medical Activities
France’s LOAC Manual (2001), under the heading “Red Cross and Red Crescent (rules of protection)”, provides:
The protection is linked to the medical purposes of the actions undertaken and finds its expression in the limitation of detention, in the granting of facilities when that personnel carries out its activity, and in the assurance not to be punished for any medical activity compatible with medical ethics.

At the CDDH, France stated: “Physicians, who were also citizens, were deeply distressed by the obligation to report wounds caused by firearms in time of war. That did not apply to the obligation to report communicable diseases.”
