Influenza.—67 cases of post-influenzal pneumonia were notified,
with 24 deaths. In 1918, there were 88 deaths from influenza,
including 54 of post-influenzal pneumonia.
Measles and Rubella.—There was no epidemic in 1919, 84 cases
only of measles, and 75 cases of rubella, were notified. I have
recommended the Council to keep these diseases notifiable in this

resulting, compared with 32 cases in 1918 with no deaths, and 37 in
1917 with no deaths.

Whooping Cough accounted for two deaths, both in children

diarrhoea, and the disease was not prevalent during last summer.f
Enteric Fever.—Three cases were notified with one death (at
home), an imported case.
Typhus.—Nil.

Cerebro-spinal Fever.—Two cases were notified as such, and
both died at home. The disease was not confirmed bacteriologically,
"contacts" showed negative results.

There were no deaths.
Malarial Sites have been pointed out to the Council, and treatment
of the same advised.
Trench Fever.—Three cases have been notified, but no lice

Dysentery.—One case has been notified in a returned soldier.
Encephalitis Lethargica.—Two cases have been notified with
