Patients not on ART or on ART with low CD4 counts are particularly susceptible, but even in patients on ART in these communities, the risk of TB remains considerably elevated compared to that of HIV-negative people, being 4-fold higher even with CD4 counts >700 cells/μL on ART.41 In our study, 6.2% (n = 12) of patients with newly diagnosed TB had a CD4 count between 350 and 499 cells/μL, and a further 5.6% (n = 11) had a CD4 count ≥500 cells/μL. Here, CD4 is linked to tuberculosis.
