Non-gonococcal urethritis contacts.

An endeavour was made to examine the female contacts of all new male N.G.U. patients attending three special treatment centres. 63-6 per cent. of the women were referred by their husbands and the remainder by other sex contacts (Table I). The 250 cases dealt with in this series were unselected except that the contacts of men who developed N.G.U. while under surveillance for gonorrhoea were excluded from the inquiry in order to avoid introducing a complicating factor.
