Screening is a targeted systematic action designed to identify diseases or pre-clinical conditions in individuals who believe they are healthy but who may in fact be at risk of a specific health impairment, and who could benefit from early treatment (or other intervention).

Some of the key challenges of community-based screening for the individual are:

1. Cost of screening (too high for the general community especially the B40)
2.  Accessibility (only available at health facilities)
3. Health screening tends to be done as a one-off and not consistently to allow a clearer assessment of one’s continuous health status
