Oncherciasis elimination, operational definition ?
O.volvulus transmission has reduced below a paicular point
Intervention has stoped
No recrudescence
All of the above
Ans. is 'd' i.e., All of the above Oncherciasis elimination The reduction of infection and transmission to the extent that interventions can be stopped, but post-intervention surveillance is still necessary. Operational definition includes ? Intervention have reduced O.volvulus infection and transmission below the point where the parasite population is beilved to be irreversibly moving to its demise/extinction in a defined geographical area. Intervention have been stopped. Post-interventional surveillance for an appropriate period has demonstrated no recrudescence of transmission to a level suggesting recovery of O.volvulus population. Additional surveillance is still necessary for timely detection of recurrent infection, if a risk of reintroduction of infection from other area remains.
