- W2076227400 abstract "Summary A pilot survey to estimate the incidence of tuberculosis was conducted in Singapore from July to October 1958. Four “sample” areas, estimated to yield some 50,000 persons over the age of 14, were selected for community survey. A total of 54,812 persons was X-rayed in 64 working days. Of these 50,673 were residents of the districts surveyed, being 82·2% of the possible total. There were in addition 4,139 non-residents. Among the residents, 1,881 cases of active pulmonary tuberculosis were detected, and 175 among non-residents, an overall total of 2,058 or 3·75% of the population surveyed. The racial distribution among residents was: Chinese 81·3%, Malaysians 12·1%, Indians and Pakistanis 6·4%. The incidence in males was nearly 2½ times that in females: 4·9% to 1·9%. The incidence in Chinese males was 5·6%, Malaysians 2·8% and Indians and Pakistanis 1·3%. The incidence of active disease was considerably greater in the crowded urban areas (4·8% and 3·6%) than in the suburban and rural areas (1·8% and 1·1%). Only 10·8% of all active cases were in the far advanced stage, and 42·1% were considered minimal. Bacteriological proof was obtained in 35% of the cases. By March 31, 1959, 1,789 patients were being given treatment. Of these 234 had been admitted to hospital and 1,555 were being treated as outpatients. Among employed people, the largest groups with active tuberculosis were in “Sales and related occupations” 604 cases, craftsmen and labourers 590, home duties 330. Inactive cases found numbered 2,064 against 2,057 active cases. Of 667 films suspected to show an abnormal cardiac shadow 323 cases of heart disease were found. 1,865 children under 14, contacts of cases found, were Heaf tested and 1,159 gave a positive reaction." @default.
