TABLE 5.

PREVALENCE PER 100,000 OF NOTIFIED, TREATED ADULT SPUTUM SMEAR–POSITIVE CASES WITH PULMONARY TUBERCULOSIS AND UNTREATED SPUTUM SMEAR–POSITIVE CASES WITH PULMONARY TUBERCULOSIS IN THE COMMUNITY, WITH ESTIMATED CASE-FINDING PROPORTION AND TIME IN YEARS BEFORE INITIATION OF TREATMENT

	HIV Positive, Smear Positive (95% CI)	HIV Negative, Smear Positive (95% CI)
Prevalence of treated PTB	1,563 (1,108–2,138)	352 (233–507)
Prevalence of total (treated and untreated) PTB	4,400 (3,619–5,299)	527 (380–711)
Case-finding proportion*	0.37 (025–0.53)	0.67 (0.41–1.0)
Estimated mean time (yr) of TB patients before treatment†	0.98	0.73

For definition of abbreviations, see Table 4.

^*Prevalence of treated PTB/prevalence of treated and untreated PTB.

^†Mean time untreated = PTB prevalence/(PTB incidence + HIV mortality rate), where the HIV mortality rate is the excess mortality associated with HIV infection in individuals notified with PTB 2002–2004.
