26 per cent. of all contacts exchanged in both directions between East Germany and Poland in 1973, concerned people infected with STD. This high rate of efficiency obtained by the present methods of contact tracing justifies further cooperative epidemiological work in the field of STD, especially in view of the increasing industrial and economic cooperation and tourism between the two countries which is expected in the future.
