33 Why are TB cases “undetected”?
estimated TB cases all true TB cases cases presenting to health facilities cases presenting to public health facilities cases presenting to DOTS facilities cases correctly diagnosed by DOTS facilities diagnosed cases reported by DOTS facilities

35 Few Chinese patients diagnosed in,
or transferred to, DOTS dispensaries Other Transfer Private clinics Diagnosis Town/village clinics TB hospitals Trad med units General hospitals TB dispensaries 50 100 150 200 Source: 2000 prevalence survey Number of patients
