SECTION IV. MEASURES ON LAND FRONTIERS—TRAVELERS—RAILROADS—FRONTIER ZONES—RIVER ROUTES
Art. 45. No land quarantines shall be established.
Only persons showing symptoms of plague, cholera, or yellow fever shall be detained at frontiers.
This rule shall not bar the right of each Nation to close a part of its frontiers in case of necessity.
Art. 46. It is important that travelers be subjected to surveillance on the part of railroad employees with a view to determining the state of their health.
Art. 47. Medical interference shall be limited to an examination of the passengers and the care to be given to the sick. If such an examination is made, it should be combined as far as possible with the customhouse inspection to the end that travelers may be detained as short a time as possible. Only persons who are obviously ill shall be subjected to a thorough medical examination.
Art. 48. As soon as travelers coming from an infected locality shall have arrived at their destination, it would be of greatest utility to subject them to a surveillance which ought not to exceed, counting from the date of departure, five days in case of plague or cholera and six days in case of yellow fever.
Art. 49. The Governments reserve the right to take special measures in regard to certain categories of persons, notably gypsies, vagabonds, emigrants, and persons traveling or crossing the frontier in troops.
Art. 50. Cars used for the conveyance of passengers, mail, and baggage shall not be detained at frontiers.
If it should happen that one of these cars is contaminated or has been occupied by a plague or cholera patient, it shall be detached from the train and disinfected as soon as possible.
The same rule shall apply to freight cars.
Art. 51. The measures concerning the crossing of frontiers by railroad and postal employees shall be determined by the companies or departments concerned and shall be so arranged as not to hinder the service.
Art. 52. The regulation of frontier traffic and questions pertaining thereto, as well as the adoption of exceptional measures of surveillance, shall be left to special arrangements between the contiguous nations.
Art. 53. It shall be the province of the Governments of the riparian Nations to regulate the sanitary conditions of river routes by means of special arrangements.
