Prisoners of war suffering from serious disease, or whose condition necessitates special treatment, a surgical operation or hospital care, must be admitted to any military or civilian medical unit where such treatment can be given, even if their repatriation is contemplated in the near future. Special facilities shall be afforded for the care to be given to the disabled, in particular to the blind, and for their rehabilitation, pending repatriation. Prisoners of war shall have the attention, preferably, of medical personnel of the Power on which they depend and, if possible, of their nationality. Prisoners of war may not be prevented from presenting themselves to the medical authorities for examination. The detaining authorities shall, upon request, issue to every prisoner who has undergone treatment, an official certificate indicating the nature of his illness or injury, and the duration and kind of treatment received. A duplicate of this certificate shall be forwarded to the Central Prisoners of War Agency The costs of treatment, including those of any apparatus necessary for the maintenance of prisoners of war in good health, particularly dentures and other artificial appliances, and spectacles, shall be borne by the Detaining Power. Medical inspections ART. 31. — Medical inspections of prisoners of war shall be held at least once a month. They shall include the checking and the recording of the weight of each prisoner of war. Their purpose shall be, in particular, to supervise the general state of health, nutrition and cleanliness of prisoners and to detect contagious diseases, especially tuberculosis, malaria and venereal disease. For this purpose the most efficient methods available shall be employed, e.g. periodic mass miniature radiography for the early detection of tuberculosis. Prisoners engaged on medical duties ART. 32. — Prisoners of war who, though not attached to the medical service of their armed forces, are physicians, surgeons, dentists, nurses or medical orderlies, may be required by the Detaining Power to exercise their medical functions in the interests of prisoners of war dependent on the same Power. In that case they shall continue to be prisoners of war, but shall receive the same treatment as corresponding medical personnel retained by the Detaining Power. They shall be exempted from any other work under Article 49.
