Abstract
Populations of school children can be utilised for the screening of ill health such as ophthalmic (Kohler et al, 1981: 369-77) and aural (Me Dermott, 1982: 462-8) conditions, heart disease (Okuni, 1982: 1250- 4), scoliosis (Lonstein et al, 1982: 481-8) or dental caries (Rebich et al, 1982: 50-53), with the sole object of clinical intervention. The target population is aimed at all belonging to a defined risk group, usually described in terms of age, sex, ethnicity and occupation.

Inter vention does not accompany sur veys. Such surveys are essential for health planning and usually denote the point prevalence of chronic problems such as trachom a (Ballard et al, 1979: 113-120), dental caries (W H O, 1977), m alnutrition (Leary, 1969: 1170-74), intestinal helm in thic infestations (S chutte et al, 1981: 137-41), bilharzia (V isser, 1984: 124-27), school girl pregnancies (Craig, 1983: 452-55) and tubercu losis (Fourie, 1981)
