For the TB indicator (number of TB cases notified), the national reporting accuracy (VF) was  82% . TB reporting is done quarterly, so the degree of matching of source documents and reports was calculated for just one reporting period (three months). Whereas 57% of TB sites were found to have perfect agreement between recounted and reported results (VF = 1.0), 31% of sites over-reported by more than 10%. Only 5% of sites under-reported by more than 10%.
