title: [Tuberculosis Annual Report 2008--Series 6. Condition of TB].
abstract: The condition of tuberculosis (TB) at the time of being diagnosed as TB influences the patient's prognosis. This paper focuses on the condition of TB at the time of being diagnosed based on bacteriological status and X-ray findings. The proportion of bacillary cases among newly notified pulmonary TB patients increased greatly from 25.7% in 1979 to 81.9% in 2008. During this period, the proportion of far-advanced cavitary cases among pulmonary TB patients was around 2% and remained stable. This may mean that diagnosis became to be performed bacteriologically rather than radiologically. The proportion of bacillary cases among newly notified pulmonary TB patients in 2008 was studied by sex and 5-year age group. The proportion of bacillary cases increased with age in both male and female TB patients. The proportion of cavitary cases increased in patients aged up to their 50's and then decreased with age. This tendency was more remarkable in male TB patients than in female. Although the proportion of cavitary cases among elderly TB patients was lower than among youths, the proportion having extensive lesions was greater than that of youths. The proportion of sputum smear positive cases with cavity among pulmonary TB patients aged 30-59 years was 32.4% in male TB patients and 20.5% in female TB patients. According to occupation, this proportion was highest in temporary workers (51.7%) for male TB cases, service workers (28.7%) for female TB cases, and lowest among "teachers/nursery nurses" in both sexes: 15.4% of male TB cases and 8.3% of female TB cases, respectively.
