What is FALSE statement ragarding HIV-associated TB is: and explain in detail?
The most infectious patients have cavitary pulmonary disease. Patients with sputum smear-negative and those with culture-negative pulmonary TB and extrapulmonary TB are essentially noninfectious. Because persons with both HIV infection and TB are less likely to have cavitations, and they are less likely to be smear positive they may be less infectious than persons without HIV co-infection.
