The Leprosy Programme and Transmission Assessment (LPTA) is an activity that is carried out by internal teams towards the end of Phase 1 (see Leprosy Elimination Framework in the Annex) when a subnational jurisdiction (typically second-tier) reaches the milestone for interruption of transmission, i.e., zero autochthonous child cases for a consecutive period of five years. It also needs to be done at the end of Phase 2, when the second milestone of elimination of leprosy disease has been reached. |
