THE SUPPRESSION OF A CHOLERA EPIDEMIC IN MANILA. 



By Allan McLaughlin." 



The cholera epidemic of September, 1908, ^vas probably a continua- 

 tion of the outbreak which had its greatest intensity in January of the 

 same year. 



There were 184 cases of cholera in Manila in January, 1908. In 

 February, 14 cases of cholera were registered, and in March 3 cases. 

 In April, cases resembling cholera clinically began to present themselves, 

 Avhich bacteriologically were negative. In May, one case bacteriologically 

 positive was reported on the 14th. One case of true cholera was found 

 on the 11th of June, and suspicious cases, resembling cholera clinically, 

 but negative bacteriologically, were found on the 3rd, 4th, 18th, 19th, 

 24th (2), 27th, 28th, and 29th. These cases resembled the true clinical 

 picture of cholera more closely from day to day. Some were fatal in a 

 iew hours, and the intestinal contents yielded a motile vibrio which 

 resembled the cholera vibrio, but did not respond to the agglutination 

 test. 



These suspicious cases continued in July as follows :
