HIV and Tuberculosis
Diagnosing TB in people with HIV infection is often difficult. They frequently have disease symptoms similar to those of TB and may not react to the standard TB skin test because their immune system does not work properly. X-rays, sputum tests, and physical exams may also fail to show evidence of tuberculosis infection in people infected with HIV.
People infected with both multidrug-resistant TB and HIV appear to have a much more rapid and deadly disease course than those who only have multidrug-resistant TB. If no medicines are available, as many as eight out of ten people with both infections may die, often within months of diagnosis.
