CD4 and tuberculosis: Although low CD4 count is a risk for progression from LTBI to active TB, respondents from both countries were less likely to be screened for LTBI in this setting (SC II: 27/51, 53 %, SC IV 15/51, 20 %), compared to those with high CD4 counts (SC I: 38/51, 75 %, and SC III: 40/51, 78 % and SC V: 23/51, 40 %, respectively).
