Abstract

THE conventional ‘parasite-rate' (percentage proportion of children aged 3–10 years in whose blood malaria parasites are detected by a single examination) may be a misleading standard of qualitative measurement giving a distorted idea of the amount of malaria in a locality. But in practice a reduction from 70 to 40 per cent is often claimed to be evidence of effective malaria control, and we are led to believe that a figure of 5 per cent is a splendid achievement indicating a very low malaria incidence.
