184 THE YELLOW FEVER CAMPAIGNS 



been necessary since my visit to quarantine on account 

 of yellow fever any sliip leaving the port of Belize, and 

 this has meant a very considerable saving of money, 

 not to mention loss of lives. 



In further confirmation of the efficiency of this 

 campaign, the Hon. Wilfred Collet, Colonial Secretary, 

 British Honduras, writes me that in 1907 an epidemic 

 of dengue fever broke out in the Colony. Naturally a 

 disease like dengue caused a very considerable amount 

 of uneasiness, on account of its close resemblance to 

 yellow fever, and as a result the INIarine Hospital 

 Service of the United States made a most searching 

 inquiry. Their representatives, however, reported that 

 there were no stegomyia to be found, and the disease 

 could not be yellow fever ! The result was that the 

 United States autliorities at once permitted the usual 

 trade facilities between the Southern States and Belize. 

 No ship was detained, and the commerce of the port 

 was not interfered with. In 1908, after a very close 

 season, the water-vats warped and the staves opened, 

 as not infrequently happens ; the result was that the 

 stegomyia began to appear again. The authorities, 

 however, immediately instituted a vigorous screening 

 campaign, which was followed by a disappearance of 

 the stegomyia in two months' time. In 1906 a 

 screening ordinance was introduced.
