We are Elrha, a force for change in the humanitarian community. The research and innovation we support equips the humanitarian community with the knowledge of what works, so people affected by crises get the right help when they need it most.
Our purpose is clear: to empower the humanitarian community to improve humanitarian response. We make this happen by supporting and championing the outcomes of robust research and proven innovations.
We empower the humanitarian community. Find out how we can support you...

4.1 Communicable disease control

4.1.6 Evidence gaps

Evidence gaps identified by key informants included:

  • The evidence base for CD interventions in crisis settings needs to be strengthened, starting with the development of agreed protocols and indicators, e.g.Sphere indicators must be reframed into something context-specific.
  • Specific evidence gaps exist around many issues related to communicable disease, including: the diseases themselves (e.g. pertussis, hepatitis A and E, and measles), methods to measure them (e.g. Lot Quality Assurance Sampling (LQAS)), and standard measurements such as mortality (e.g. age and gender specific).
  • Designs to conduct and assess immunisations are problematic, with LQAS being employed by many but debated by a few experts who question its appropriateness.
  • CD is context, disease and crisis specific – e.g. currently there is almost no evidence on CD control in Syrian populations; age/gender specific information is needed, even on mortality.
  • Surveillance must be enhanced across all settings, once indicators are agreed upon; current surveillance focuses on measles but target ages are changing and schedules being revised.
  • There is no evidence on whether a coordinated humanitarian approach will improve targets; research could be done on current versus coordinated approaches.
  • Huge gap in understanding of human side of CD control; more anthropological/sociological research is needed for CD intervention success (e.g. acceptability).
  • Research could validate clinical versus laboratory confirmed outcomes for CD interventions.
