Table VIII.—Deaths following Influenzal Infections (whole Dominion), including those due to Cerebro -spinal Fever.

Table VII must be taken as representing the minimum deaths due Io influenzal infection, and it does not include deaths occurring among the Natives, regarding whom the following particulars as to deaths are available : —

Table IX. — Maori Deaths from Respiratory Diseases from 1st August, 1917, to 31st December, 1918.

It- is not possible to say exactly what proportion of these Native deaths were due to primary influenzal infection, but it is obvious that the high returns for November and December were caused by the secondary pandemic wave spreading among the Maoris. It is also probable I hat the primary v r ave exercised its chief influence in September, when the death-rate is shown to be high. Of the twenty-nine deaths during the month, twenty-four of these Natives were in the Auckland Province. That influenza was prevalent among the Natives from July onwards is shown by the following table, compiled from the reports of the .medical officers in charge of Natives in the Wellington Provinoe in regard to the cases attended by them : —

Table X.

The majority of the earlier cases were in the Waiapu County. After September they were more widely distributed. A steadily increasing wave of infection from July onwards is very marked, as also the sudden rise in November, when the second wave became manifest. These figures represent only the more serious cases coming to the notice of the medical officers. by no means represent the actual incidence. Table VII does not show any definite crest for the primary wave, but, rather a steadily increasing virulence from July onwards; but as regards the secondary wave the abnormal returns for November show that the apex occurred in this mouth. Kxamining in detail the figures indicating the deaths from influenza and its complications during the months of October, November, and December we get the following results : — Table XI. — Deaths from Influenza during Epidemic.
