Taeniosis and cysticercosis are two parasitic diseases that in the past have not always been recognised for their importance. However, it is becoming increasingly clear that greater priority should be given to them because of their economic impact, particularly in resource poor countries, and their public health burden. It also is now recognised as an increasing problem in some countries. The now accepted linkage between epilepsy and neurocysticercosis in countries endemic for Taenia solium is further impetus for allocating more effort to the control of taeniosis/cysticercosis. 

As is the case for all zoonoses, the control of taeniosis/cysticercosis, requires a very close collab
oration between both veterinary and medical public health services at a national level. It was with the aim of assisting those responsible for taeniosis/cysticercosis control and prevention that these Guidelines were prepared and jointly published by the Food and Agriculture Organization (FAO), the World Health Organization (WHO) and the World Organisation for Animal Health (OIE). 

The WHO/FAO/OIE Guidelines for the Surveillance, Prevention and Control of  Taenisosis and Cysticercosis is a compilation of the knowledge and valuable expertise of a great many internationally recognised experts on this zoonosis, accumulated over more than a hundred years of research. With out this knowledge base, effective and proven recommendations for diagnosis, treatment, prevention
and control will not be possible. 

Since the publication of an earlier guideline (1983), greater understanding of the zoonosis’ epidemiology and effective control design has been achieved, assisted greatly by the development of new and better diagnostic technologies. Clinical management and treatment approaches (especially imaging) have also greatly advanced. This guideline brings these advances together, in a practical format, to help those with the responsibilities for confronting this zoonosis. 

These Guidelines cover the biology, systematics, epidemiology, diagnosis, prevention and control of taeniosis and cysticercosis, in humans, cattle and pigs. The Chapters include descriptions of methods, and procedures for clinical management, including treatment, for conducting risk assessment studies, and for prevention and control programmes. The recent technologies introduced for the detection and diagnosis of infection are described. The Guidelines provide advice and recommendations on program planning, monitoring and evaluation. Intersectorial cooperation is emphasised.
