Commenting on the year's work, Dr. J. M. Morgan, director of
the south-east London mass x-ray service, states:—
"Of the fifteen cases requiring close supervision or treatment
seven were discovered at public surveys, four men and three women,
giving an incidence of 2.9 and 1.6 respectively, with an overall incidence
of 2.2 per thousand. Not one of these cases found had been previously
x-rayed, and the incidence in this sample of the un-x-rayed population
is therefore 4.7 for men and 2.5 for women, with an overall incidence or
3.4. Seven cases requiring close supervision or treatment were found
in firms, six men and one woman, giving an incidence of 5.1 and 1.1 per
thousand respectively, with an overall incidence of 3.4. Of these seven
cases, only one had been previously x-rayed, and the incidence in the
un-x-rayed group is therefore very high at 12.3 per thousand for men,
and 2.4 for women, giving an overall incidence of 8.4 per thousand.
The other case was a schoolboy. These figures reveal once more the
extent of tuberculosis in London, particularly among those who have not
yet had chest x-ray examination, and provide reasonable grounds for
urging all those concerned with the problem to make every effort to
bring unexamined persons to mass x-ray units.
