Excerpt
Introduction This is the second issue of the Bulletin of the World Health Organization to be devoted to bilharziasis within twelve months, and the papers presented here may be considered complementary to the earlier collection,l dealing largely with the same subjects. Epidemiology is discussed by McMullen & Francotte in a report on a survey in Upper Volta in which the now familiar pattern of difficulties involved in initiating disease control in developing countries is unfolded. In the absence of a strong national public health service with trained personnel enjoying the full confidence of an enlightened people, disease control becomes a mere cipher. One aspect of 'this thorny control problem which deserves the fullest attention is that of water resources development, because something can be done about it now. The prevention, wherever possible, of the creation of conditions which might serve to aggravate the difficulties already existing is imperative. This matter is dealt with by McMullen, Buzo, Rainey & Francotte, who have examined the situation in 15 countries in Africa and the Middle East; they point to the very important and seemingly obvious advisability of calling in health experts during the pre-operational planning of large irrigation and other development schemes. We know now how important water management can be in the control and even the prevention of bilharziasis, and it is clearly necessary that snail ecologists should be consulted at the planning stage. The complex and difficult situation created by the irrigation schemes in the Sudan in well illustrated in Malek's paper by the fact that he lists no fewer than seven subjects requiring further research before really adequate snail control can be achieved.
