Although the provision of public water supplies has undoubtedly been the principal factor in reducing the incidence of Typhoid Fever and allied diseases in the Colony, there still remain other ways of acquiring infection.
Twenty to thirty years ago, there was in this colony a widespread belief that Chinese did not suffer from Typhoid Fever to any appreciable extent. The old reports of the Colonial Surgeon had been forgotten. It is probably true that the Chinese have a higher degree of immunity to this disease than have Europeans of these days. This, combined with the habit of tea drinking, which means that drinking water is boiled, now accounts probably to a great extent for the difference in incidence of the disease between Chinese and non-Chinese residents.
At the same time, the infection of non-Chinese was generally ascribed to the eating of vegetables, especially in salads, grown by Chinese and therefore by the use of manure from human sources, and also by the eating of oysters.
