No necessity for second fumigation. — In the same Article there is 
agreement about non-necessity of second fumigation, provided that no new 
cases shall have appeared, or that the ship shall not have touched at an 
infected port, and that the first fumigation was carried out efficiently. 
ImMunes to be exempted. — The exceptional position of the immune is 
recognised by both Conventions, compare Article XLIX. (Pan-American) 
and Article XII. (West Indian). 
Treatment of Merchandise. — Both agree that merchandise be not 
disinfected, Article XII. Pan-American Convention, and Article XIV. 
West Indian Convention But in Article XII. (Pan-American) it will 
be seen that the vehicle of transportation may be fumigated. 
Mails. — Both agree are not to be fumigated. 
Baggage. — Both agree are not to be fumigated. 
Departure of Passengers from an infected area. — There are differences 
here between the precautionary measures to be taken according to the 
two Conventions. By the Pan-American Convention no restrictive 
measures are to be taken if the departures have occurred at least five days 
before the commencement of the epidemic. The West Indian Conference 
provides simply for an examination by the Medical Officer immediately 
before the departure of the vessel. 
Regulations affecting Passengers travelling under surveillance. — There 
is nothing in the Articles of the Pan-American Conference dealing- with 
o o 
permission being given to travellers to proceed to their destination as 
is the case with the West Indian Conference in Article XIII. 
Prevention of access of mosquitoes to skip. — In Article XVII. of the 
West Indian Conference it is stated that measures are to be taken to prevent 
mosquitoes gaining access to the ships, and if this is not possible that 
measures “ should be taken ” to secure the destruction of the mosquitoes 
on board immediately before the departure of the vessel. Nothing is said 
as regards proximity to shore, a point laid stress upon by the Pan-American 
Conference.
