having been in communication with the shore, it lands only passengers and their baggage and the mail, or takes on only the mail, or passengers with or without baggage who have not communicated with the port or with a contaminated area. In case of yellow fever, the vessel must besides have kept away from shore as much as possible, and at a distance of 200 meters, in order to prevent the invasion of mosquitoes.
Art. 38. A port authority who applies sanitary measures shall deliver to the captain, owner, or agent, whenever requested, a certificate specifying the nature of the measures and the reasons for which they have been applied.
Art. 39. Passengers arriving on an infected vessel shall have a right to demand a certificate of the health authority of the port showing the date of their arrival and the measures to which they and their baggage have been subjected.
Art. 40. Coasting vessels shall be subjected to special measures to be established by mutual agreement among the countries concerned.
Art. 41. The Governments of riparian Nations on the same sea may conclude special agreements among themselves, taking into account their special situations and in order to render more effective and less annoying the application of the sanitary measures provided by the Convention.
Art. 42. It is desirable that the number of ports provided with a sufficient organization and equipment to receive a vessel, whatever be her sanitary condition, should, in the case of each Nation, be in proportion to the importance of traffic and navigation. However, and without prejudice to the rights of the Governments to agree on organizing common sanitary stations, each country should provide at least one of the ports on the coast line of each of its seas with such an organization and equipment.
Moreover, it is recommended that all great ports of maritime navigation be equipped in such a way that at least uninfected vessels may undergo the prescribed sanitary measures therein as soon as they arrive and not be sent to another port for this purpose.
The Governments shall make known the ports which are open in their country to arrivals from ports contaminated with plague, cholera, and yellow fever, and particularly those which are open to infected or suspicious vessels.
Art. 43. It is recommended that there be established in large maritime ports:
- a) A regular medical service of the port and a permanent medical surveillance of the sanitary conditions of the crews and the inhabitants of the port.
- b) Means for the transportation of patients and places set apart for their isolation and for the observation of suspected persons.
- c) The necessary plants for efficient disinfection, and bacteriological laboratories.
- d) A supply of drinking water beyond suspicion for the use of the port, and a system affording all possible security for carrying off refuse and sewage.
