The number of deaths from Malaria in 1925 is very slightly less than in 1924 but it is quite probable that, if there had not been such a large exodus from the Colony during and after the "Strike" at the end of June, the deaths from this disease would have been higher than in 1924.
The ratio of deaths from Malaria per 1,000 of the estimated population for the year shows a decrease when compared with the figures for 1924. This may also be merely due to the above mentioned exodus having decreased the actual population during the latter half of the year.
The figure showing the ratio of deaths from Malaria to the total deaths registered in 1925 was 4.68 per cent. This is the highest percentage reached during many years as shown by the table given below.
The following table shows for twelve successive years the deaths in the Colony from Malaria Fever expressed as a percentage of the total deaths registered each year and the incidence of such deaths per thousand of the population
Year Total deaths from Malaria Deaths from Malaria per cent. of total deaths Deaths from Malaria per 1,000 of population 1914 241 2.51 0.58 1915 328 4.14 0.78 1916 337 3.19 0.78 1917 411 3.93 0.92 1918 388 2.93 0.83 1919 314 2.69 0.62 1920 332 2.67 0.59 1921 332 3.79 0.55 1922 454 3.11 0.78 1923 674 4.33 1.14 1924 707 4.54 1.96 1925 702 4.68 0.89This table suggests that Malaria Fever has increased its incidence during recent years.
The increase is probably due mostly to a very considerable increase in the prevalence of this disease in Kowloon which is strongly suggested by the table, given below, showing the deaths from Malaria in Kowloon.
