The months of highest rainfall in 1938 were May (8.7 inches), July (12.2 inches) and August (7.88 inches).
The suggested association (Russell) between high relative humidity and high temperature accompanied by intermittent rains and the incidence of cholera in Hong Kong is certainly not a close one.
Certain authorities (Rogers) hold the view that cholera becomes epidemic only when the absolute humidity rises above 0.4 inch.
It is certainly a fact that the monthly absolute humidity figure was 0.91 inch in July at the peak of the outbreak and in August when a secondary peak was noted; however, the average monthly absolute humidity figure was 0.67 inch for the year, was over 0.8 inch from May to September and never below the figure of 0.4 inch mentioned above.
Under the circumstances, it would be unwise to draw any very definite conclusions regarding the influence of climatic conditions on the incidence of cholera in Hong Kong, except to suggest that there was a tendency for outbreaks to occur at a period of the year when temperature and rainfall are usually higher than during other periods. P.S.S-C.

Note: The returns for the Government hospitals are given separately from those of the Chinese hospitals although both treat Chinese patients. The reason for this separation lies in the fact the Chinese hospitals are, for the most part, so overcrowded and short of qualified staff that it is very difficult to secure an accurate diagnosis of the cases of disease in a large proportion of those treated.
