For the past five or six years, epidemics of cholera have occurred every summer in Japan and the early cases in each outbreak are believed to have been imported from Manila or Shanghai.
Port quarantine in Japan has consequently been strict. Specimens of excreta from passengers and crew of vessels arriving from infected ports require to be examined bacteriologically and declared free before landing is permitted. The method is irksome and laborious though probably effective.
