64 CHOLERA 



Certain cities in Italy, notably Naples and Genoa, have in recent 

 years been mildly infected and the disease has been kept alive by 

 contact infection, but their water-supplies being free from pollution, 

 severe outbreaks have not developed. Suspected persons and their 

 families and neighbors should be tested by an examination of their 

 stools and kept under observation so long as these contain the bacilli. 

 A convalescent may carry the organism in his intestine and expel it 

 in his feces for sixty days after recovery. Many who do not develop 

 the disease carry the bacilli and distribute them in their stools.
