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
186 cases of Respiratory Tuberculosis and 23 cases of NonRespiratory
Tuberculosis were notified on Form A during 1956
(Table 1 - Formal Notifications). Of these 115 males and 7 1
females were Respiratory cases and 9 males and 14 females were
Non-Respiratory. In addition 132 Respiratory cases and 8 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 1956
by notification or otherwise was 349 as compared with 261 in
1955, 336 in 1954, 304 in 1953 and 331 in 1952.
318 of these were cases of Respiratory Tuberculosis; 183 in
males and 135 in females. There were 23 more males and 62 more
females than in 1955.
There were 6 cases of Non-Respiratory Tuberculosis among
children under 15 years as compared with 6 in 1955. The number
of cases in adults was 25 compared with 22 in 1955.
Of the cases notified in 1956, 20 males and 5 females died
from the Respiratory form of the disease during the year, equal
to 6.5 per cent, of those notified.
The incidence rate of Tuberculosis of all forms was 1.40 per
1,000 of the population; for Respiratory Tuberculosis 1.28 and
for Non-Respiratory 0.12 per 1,000 population. The notification
rate was 0.84 per 1,000. In 1955 the corresponding figures were
!• 04, 0.93, 0.11 and 0.69 per 1,000.
