Best estimate of annual prevalence
(Aged 15-64 unless otherwise indicated)
Except where the prevalence values are taken from household surveys, changes between years need to be interpreted with caution as they might reflect a change in the methodology or the data source from which the estimate was derived and therefore should not be considered as a change in prevalence.
Method: HHS = Household survey, SS = School survey, A = Adjusted from other sources, I = Indirect estimates, R = Registry.
