Population estimates of extrapulmonary tuberculosis (EPTB) and proportion with drug resistance in Tshwane by age group and sex in 2015. Figure 2a show that the estimated EPTB incidence stratified by age and gender. As shown the estimates in females was 3.54 (95% CI: 2.68–4.60), while that in males was 5.31 (95% CI: 4.24–6.58) per 100, 000 populations for the year 2015. Figure 2b show the proportion of total isolates (N = 70) by anatomic EPTB and within each category the percent of isolates with resistance to either rifampin or isoniazid or both. As shown, none of the isolates from peritoneal specimen, disseminated (i.e., blood or bone marrow) and other specimen samples were drug resistant. Figure 2c stratifies drug resistance by age, and as shown one out of the 5 isolates from children were drug resistant, and that same isolate was also rifampin resistance
