Overview

Screening of malaria is important in Sub-Saharan refugees and blood donors.[1]

Screening

Screening for malaria infection is important in:[1]

  • Sub-Saharan refugees
    • A sub-optimal alternative to presumptive therapy is to test newly arriving for malaria infection.
    • Studies have demonstrated that a single malaria thick-and-thin blood smear lacks sensitivity for detecting asymptomatic or sub-clinical malaria in these populations.
    • Three separate blood films taken at 12 to 24 hour intervals, the standard recommendation for diagnosis of clinical malaria, has a greater sensitivity. However, this approach is rarely feasible for screening newly arriving refugee populations because of cost constraints and the need for multiple visits.
    • When a refugee does not receive presumptive therapy they should be monitored for signs or symptoms of disease, particularly during the initial 3 months after arrival, regardless of the post-arrival testing results.

WHO Guidlines

  • In 1968, the World Health Organization published guidelines for the establishment of a screening program that can be summarized in 10 principles:
  1. The disease should be an important health problem.
  2. The natural history of the disease should be understood adequately.
  3. A latent stage of the disease occurs.
  4. A test for the disease is available.
  5. The test is acceptable to the population.
  6. Treatment for the disease exist.
  7. facilities for diagnosis and treatment are available.
  8. A policy about who to treat has been agreed on.
  9. Case finding costs should be considered in relation to medical expenditure as a whole.
  10. Case finding should be organized as an ongoing process rather than a one-time only project.
  • These guidelines form the theoretic basis of most screening programs including malaria that are currently in use.
