The prevalence of pulmonary tuberculosis in the Durban clothing industry
Abstract
After an extensive mass X-ray survey of industrial workers in Durban in 1952,1 it was noticed that there was a high prevalence of pulmonary tuberculosis amongst workers in the clothing industry. As a result of this finding, which was not unexpected in view of previous reports,2 it was decided to make a thorough study of this section of industry. A survey was carried out in the latter part of 1953 during which more than 99% of 7,510 clothing workers in Durban were X-rayed on mass miniature film (70 mm.) with a follow-up of clinical investigation and 10" X 15" X-ray of cases discovered.
