The control of venereal disease.

The recent dramatic increase in the transmission of venereal disease is not an isolated social phenomenon but is one manifestation of the alteration in the behaviour of society during the last decade (Guthe and Willcox, 1971). Behaviour patterns vary in different social and ethnic groups and are greatly altered by environmental pressures. Any consideration of the difficulties associated with locating a patient with infection must be related to the medical and social conditions which exist in his area at the time. Failure to locate the patient with infection may be due to factors inherent in the patient himself, in his environment, or in the control system. In some countries the evolutionary process of medicine segregated patients with venereal diseases in special clinics. This was undoubtedly the result of the social implications of such diseases (Brain, 1964). Geographical separation of the clinics from other branches of medicine encouraged professional isolation. Secrecy bred fear and ignorance in the lay public. This is still the cultural environment of some of our medical colleagues. When one considers the individual patient, one must always remember that he will reflect his environment in both knowledge and behaviour. The patient who has venereal disease may be unaware of his infection. This may be because his infection is asymptomatic (Pariser, Farmer, and Marino, 1964) (a more common occurrence in women than in men and in the homosexual than in the heterosexual). It may also be that he does not relate his symptoms to the probability of sexuallytransmitted disease. This is easily understood when one considers that his main symptom could be that of pharyngitis (Owen and Hill, 1972), a cutaneous rash, or genital pruritus. It could also be due to his not having been instructed in the symptomatology of venereal disease. Although aware of the possible nature of his infection, the potential patient may be frightened to attend the public clinic because he fears the social
