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.
- Blood donors
WHO Guidlines
- In 1968, the World Health Organization published guidelines for the establishment of a screening program that can be summarized in 10 principles:
- The disease should be an important health problem.
- The natural history of the disease should be understood adequately.
- A latent stage of the disease occurs.
- A test for the disease is available.
- The test is acceptable to the population.
- Treatment for the disease exist.
- facilities for diagnosis and treatment are available.
- A policy about who to treat has been agreed on.
- Case finding costs should be considered in relation to medical expenditure as a whole.
- 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.
