The disease is not notifiable and so its prevalence can only be judged from the number of deaths due to it.
The following table shows the deaths registered as due to Influenza during the years 1918 to 1922 inclusive.

Paratyphoid Fever was not a notifiable disease in Hongkong prior to 1914.
During the early years of the Colony many deaths were ascribed to continued fever. This term gradually fell into disuse with more accurate means of diagnosis, but it is probable that many cases of Paratyphoid Fever were notified as Typhoid Fever and that the term Continued Fever covered both these groups.
