The fitness of prisoners of war for work shall be periodically verified by medical examinations, at least once a month. The examinations shall have particular regard to the nature of the work which prisoners of war are required to do.

If any prisoner of war considers himself incapable of working, he shall be permitted to appear before the medical authorities of his camp. Physicians or surgeons may recommend that the prisoners who are, in their opinion, unfit for work, be exempted therefrom.
