... 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. ...

... Every death or serious injury of a prisoner of war caused or suspected to have been caused by a sentry, another prisoner of war, or any other person, as well as any death the cause of which is unknown, shall be immediately followed by an official enquiry by the Detaining Power. ...

... Upon the outbreak of a conflict and in all cases of occupation, each of the Parties to the conflict shall institute an official Information Bureau for prisoners of war who are in its power. Neutral or non-belligerent Powers who may have received within their territory persons belonging to one of the categories referred to in Article 4, shall take the same action with respect to such persons. The Power concerned shall ensure that the Prisoners of War Information Bureau is provided with the necessary accommodation, equipment and staff to ensure its efficient working. It shall be at liberty to employ prisoners of war in such a Bureau under the conditions laid down in the Section of the present Convention dealing with work by prisoners of war. ...

... The function of the Agency shall be to collect all the information it may obtain through official or private channels respecting prisoners of war, and to transmit it as rapidly as possible to the country of origin of the prisoners of war or to the Power on which they depend. It shall receive from the Parties to the conflict all facilities for effecting such transmissions. ...

... The High Contracting Parties shall communicate to one another through the Swiss Federal Council and, during hostilities, through the Protecting Powers, the official translations of the present Convention, as well as the laws and regulations which they may adopt to ensure the application thereof. ...

... The present Convention is established in English and in French. Both texts are equally authentic. The Swiss Federal Council shall arrange for official translations of the Convention to be made in the Russian and Spanish languages. ...
