connected with the fact that women lead a more sheltered existence
than men in the later years of life. The higher proportion of deaths
in young adult females is probably accounted for by the increasing
numbers employed at these ages and by the lack of a proper adjustment
to the more strenuous way of life in modern times.
The number of new cases of Pulmonary Tuberculosis in 1937 in
the age groups 15 to 35 years was greater than in 1936, but whereas
in 1936 the greatest number occurred in the 20-25 years group, in
1937 the greatest number was in the 25-35 group.
The greater proportion of new cases of Pulmonary Tuberculosis
were in the age groups comprising 20 to 45 years. In the age groups
15 to 25 years there was a greater number of new cases among
women but after 25 years there was a greater number in men.
There is a close similarity between the age distribution of new cases
and of deaths from Pulmonary Tuberculosis. This year the peak
of new cases was in the 25-35 age group. The figures indicate that
Pulmonary Tuberculosis is a rare disease in the first ten years of life.
It is rather disappointing to find that although there has been
a great fall in the number of new cases and deaths compared with
20 years ago, there has been no appreciable change in the ratio of
new cases to deaths. In other words, for every 100 cases developing
Tuberculosis to-day about the same number die from the disease as
was the case 20 years ago. It has been shown, however, that
modern methods of treatment prolong the lives of those who are
found to be suitable for such treatment.
Deaths from Non-Pulmonary Tuberculosis.
