Answer

Co-infection with HIV and tuberculosis is very common in developing nations. Immunosuppression from HIV infection contributes not only to a higher rate of tuberculosis reactivation but also to an increased disease severity.

Tuberculosis skin testing should be performed and a 5-mm purified protein derivative (PPD) result interpreted as positive. Alternatively, interferon (IFN)-gamma release assays have been shown to be safe and reliable in pregnancy to screen for latent tuberculosis. [41] If screening test is positive, chest radiography can be performed during pregnancy because radiation risk is exceedingly low.
