Whilst this section of the report is concerned with Tuberculosis
it should be realised that all chest conditions are seen
and treated at the Chest Clinic. With the decline in Tuberculosis
we are seeing an increase in the incidence of lung
cancer and chronic bronchitis. The former accounts for the
highest number of cancer deaths in males and the latter causes
much chronic invalidism and loss of earning capacity.
Incidence
147 cases of Respiratory Tuberculosis and 15 cases of NonRespiratory
Tuberculosis were notified on Form A during 1957
(Table I - Formal Notifications). Of these 94 males and 53
females were Respiratory cases and 7 males and 3 females were
Non-Respiratory, in addition 121 Respiratory cases and 11 NonRespiratory
cases came to our notice as new cases otherwise than
by notification. (Table II - Supplemental Return).
The total number of new cases of Tuberculosis coming to the
knowledge of the Medical Officer of Health during the year 1957
by notification or otherwise was 294 as compared with 349 in
1956, 261 in 1955, 336 in 1954 and 304 in 1953.
268 of these were cases of Respiratory Tuberculosis; 165
in males and 103 in females. There were 18 fewer males and 32
fewer females than in 1956.
There were 5 cases of Non-Respiratory Tuberculosis among
children under 15 years as compared with 6 in 1956. The number
of cases in adults was 18 compared with 25 in 1956.
Of the cases notified in 1957, 2 males and 5 females died
from the Respiratory form of the disease during the year, equal
to 4.8 per cent. of those notified.
The incidence rate of Tuberculosis of all forms was 1. 18
Per 1,000 of the population; for Respiratory Tuberculosis 1.07
and for Non-Respiratory 0.10 per 1,000 population. The notification
rate was 0.65 per 1,000. In 1956 the corresponding figures
were 1.40, 1.28, 0.12 and 0.84 per 1,000.
