TB Program And Vaccine Approaches

HIV also alters the symptoms of TB, such that, in an immune competent person, a cough for 2 weeks or more in duration has a high sensitivity of detecting active TB, while in PLHIV, cough alone misses significant numbers. However, the addition of fever, weight loss and night sweats to the symptom screening questions can greatly increase the sensitivity to detect TB in PLHIV. Unfortunately, 10% to 40% who come to medical attention at some community health centers are lost to follow-up because of inconsistent symptom screening at all steps of healthcare delivery, as well as delays in laboratory testing and reporting of results.
