Overall, CITC was higher in almost all identifiable groups than PITC with exceptions of “other ethnicity” and “unknown educational level”, (see Table 1). Looking at overall coverage of testing and counselling i.e. sum of CITC and PITC, the highest percentages of individuals who had ever been tested were those in the age bracket 20 to 34 years (Table 1).
