The total cases numbered 285 as compared with 302 in 1923. These figures include all notified cases including imported cases, those treated in hospitals in Hong-Kong but with their places of residence in the New Territories, and all cases notified as occurring in the Navy and Army.
The figures showing the population belonging to the Navy and Army during the years of the war are not available.
As however these numbers are small in proportion to the total population, the following table is inserted.
This table shows the incidence per 1000 on the civil population of Typhoid and Paratyphoid Fevers, all cases of these diseases being included in the calculation.

The census figure for the population is used in the above table and the populations for the following years are based on this figure, but some endeavour has been made to correct them as the census for 1921 was admitted to be too low.
If the estimated population for the year 1921 be used instead of the census figure the rate per 1000 for that year falls to 0.282.
For the year 1920 to 1924 it has been possible to calculate the incidence per 1000 of Typhoid and Paratyphoid Fevers on the civil population, excluding all cases of these diseases amongst the Naval and Military forces, all imported cases, and cases brought into hospitals from the New Territories.
