Monitoring and Evaluation of the process is essential to assess the extent of functioning of the programme whereas impact evaluation is useful to assess the programme effectiveness. It is essential to develop proper evaluation methods with common protocol for programme optimization and also for its extension to other areas. To develop appropriate monitoring methods it is necessary to identify the indicators of process of implementation and the impact of interventions.

  • Surveillance of potential transmission or established human infection in an unsurveyed population is necessary to determine where control efforts should be initiated, how effective they are, and when they may be discontinued.


  • There is a major need to replace night blood surveys as the primary method for determining the levels of endemicity in a community.


  • Evaluation of antigenaemia rates in daytime, finger-prick blood specimens from children or other selected cohorts of the population has proven to be a workable alternative to night blood surveys.


  • Analysis of infection rates in mosquito vectors with DNA based techniques show equal promise.


  • 'Rapid assessment' techniques, such as review of existing health reports and hospital records or clinical examination of adult males for hydroceles to assess the prevalence of infection, are also being developed as 'tools' for identifying endemic communities in previously unsurveyed areas.


  • Mathematical models are the powerful tools for analysis, prediction and evaluation of control strategies in other parasitic infections, and such models should be particularly valuable for lymphatic filariasis because of the complexity of the long time-scales involved in filarial infection and disease.


  • Models for studying the population dynamics of transmission and for assessing the consequences of control interventions and their relative cost-effectiveness are under development.
