The International Sanitary Convention signed at Washington, 

 October 14, 1905, follows the text of the Paris convention, with 

 respect to plague, consequently embodying similar requirements and 

 recommendations as follows: 



ART. XX. Classification of ships. A ship is considered as infected which has plague, 

 cholera, or yellow fever on board, or which has presented one or more cases of plague 

 or cholera within seven days, or a case of yellow fever at any time during the voyage. 



A ship is considered as suspected on board of which there have been a case or cases 

 of plague or cholera at the time of departure or during the voyage, but no new case 

 within seven days; also such ships as have lain in such proximity to the infected 

 shore as to render them liable to the access of mosquitoes. 



The ship is considered indemne which, although coming from an infected port, 

 has had neither death nor case of plague, cholera, or yellow fever on board, either 

 before departure, during the voyage, or at the time of arrival, and which in the case 

 of yellow fever has not lain in such proximity to the shore as to render it liable, in 

 the opinion of the sanitary authorities, to the access of mosquitoes. 



ART. XXI. Ships infected with plague are to be subjected to the following regu- 

 lations: 



1. Medical visit (inspection). 



2. The sick are to be immediately disembarked and isolated. 



3. Other persons should also be disembarked, if possible, and subjected to an obser- 

 vation, <* which should not exceed five days, dating from the day of arrival. 



4. Soiled linen, personal effects in use, the belongings of crew & and passengers 

 which, in the opinion of the sanitary authorities are considered as infected, should be 

 disinfected. 



5. The parts of the ship which have been inhabited by those stricken with plague, 

 and such others as, in the opinion of the sanitary authorities, are considered as infected, 

 should be disinfected. 



6. The destruction of rats on shipboard should be effected before or after the dis- 

 charge of cargo, as rapidly as possible, and in all cases with a maximum delay of 

 forty-eight hours, care being taken to avoid damage of merchandise, the vessel, and 

 its machinery. 



For ships in ballast, this operation should be performed immediately before taking 

 on cargo. 



ART. XXII. Ships suspected of plague are to be subjected to the measures which 

 are indicated in Nos. 1, 4, and 5 of Article XXI. 



Further, the crew and passengers may be subjected to observation, which should 

 not exceed five days, dating from the arrival of the ship. During the same time 

 the disembarkment of the crew may be forbidden, except for reasons of duty. 



The destruction of rats on shipboard is recommended. This destruction is to be 

 effected before or after the discharge of cargo, as quickly as possible, and in all cases 

 witha maximum delay of forty-eight hours, taking care to avoid damage to merchandise, 

 ships, and their machinery. 



For ships in ballast this operation should be done, if done at all, as early as possible, 

 and in all cases before taking on cargo. 



ART. XXIII. Ships indemne from plague are to be admitted to free pratique 

 immediately, whatever may be the nature of their bill of health. 



a The word "observation" signifies isolation of passengers, either on board ship or 

 at a sanitary station, before being given free pratique. 



& The term "crew" is applied to persons who may make, or who have made, a 

 part of the personnel of the vessel and of the administration thereof, including stewards, 

 waiters, "cafedji, " etc. The word is to be construed in this sense wherever employed 

 in the present convention.
