THE HONGKONG GOVERNMENT GAZETTE, 2ND JUNE, 1905.
Kowloon District III.—Yaumati.
This district also presents the wave appearance in the rat curve though in a less distinctive manner than do the curves for Victoria and all Kowloon.
The table will shew that the rat curve may be divided into at least three wave periods, namely, weeks 31 to 33 and 37 to 49, 1903, and one long wave for the whole of the period from the 1st to 31st weeks of 1904.
With the 1st wave we have the tail end of the 1903 epidemic.
Corresponding to the second rat wave which is the most intense on the chart there are no human cases recorded.
The few human cases that occurred during the 1904 epidemic began eleven weeks after rat plague began to be fairly continuous, but extended on to the 31st week of 1904 together with the rat plague.
