REPORT OF THE TUBERCULOSIS OFFICFR.
To the Medical Officer of Health.
Sir,
During 1929 there has been no material change in the
work of the Department, and the following Report calls for no
special comment this year.

These figures give an Incidence Rate for all forms of the
disease of 1.72 per 1,000 of the population (1.46 pulmonary
and .26 ron-pulmonary), with a Death Rate for all forms of 1.13
per 1,000 population (1.04 pulmonary and .10 non-pulmonary).
In 5 instances (4 pulmonary and 1 non-pulmonary) the diagnosis
of Tuberculosis was not confirmed after observation at Dispensary
or Hospital, so that the above Incidence Rates should be read
at a slightly lower figure.
The Death Notification Interval of 79 patients (77
pulmonary and 2 non-pulmonary) who died of Tuberculosis in
1929 is shown below: —
Information from Death Returns 2
Died within One Month of Notification 2
Died within Three Months of Notification 7
Died within Six Months of Notification 11
Died with Over Six Months of Notification 57
Revised Diagnoss.—The 5 cases in which diagnosis was
not confirmed comprised:—3 Bronchitis and 1 Heart Disease,
notified as suffering from Pulmonary Tuberculosis; and 1 case
of simple enlargement of the neck glands notified as Nonpulmonary
Tuberculosis.
Deaths.—During the year 120 persons died from Tuberculosis (all forms), giving a Death Rate of 1.13 per 1,000
population; 108 were due to the pulmonary form, equal to a
rate of 1.04 per 1,003 which is .01 higher than the figure
recorded last year.
