"Attributes" of Neglected Zoonotic Diseases NZD affect mostly populations of the tropical and subtropical areas of the world which are the poorest and most vulnerable. NZD largely affect livestock and animal owners and their families so that their prevention and control will benefit both human and animal health. Prevention and control of NZDs,, by simultaneously saving lives and securing livelihoods, offers a very real and highly cost- effective opportunity for alleviating poverty especially in remote rural and marginalized peri-urban communities. NZD occupy a unique position at the interface between human and animal health as they require very strong collaboration and sustained commitment
A disproportionate burden is borne by the poor Poor prognosis once infected More at risk of acquiring a zoonosis Greater Burden borne More vulnerable to illness From A. Shaw in her presentation made to the Consultation on Integrated Control of NZDs, Nairobi, November 2007.

Overlap of zoonotic diseases WHO/OMS Overlap of five selected neglected zoonotic diseases (NZDs)* at the country level in Africa. More than 30% of countries have three or more of these NZDs in various combinations. *The NZDs are cutaneous leishmaniasis (anthroponotic and zoonotic), zoonotic trypanosomiasis, echinococcosis, cysticercosis and rabies.

"Attributes" of Neglected Zoonotic Diseases There is a lack of: information and awareness about the extent of the problem, suitable diagnostic and management capacity, and appropriate and sustainable prevention and control strategies. There is a false perception that their burden and impact on society is low, such that they neither attract the health resources nor the research needed to control them.

Integrated control of NZDs: : from WHO/OMS Concept to Action Recent WHO initiative: Concept and "labelling" of integrated NZD dates back to 2004. Report of the Meeting of Sept. 2005 very well received. Attracted attention of funding agencies e.g EU Research Directorate. Report of the 2007 consultation now available WHO is currently tackling some of the practical, institutional, political and resources related issues associated with this initiative.
Integrated control of neglected zoonotic diseases in Africa Applying the one health concept Report of a Joint WHO/EU/ILRI/DBL/FAO/OIE/AU Meeting ILRI headquarters, Nairobi, Kenya 13 15 November 2007
"Challenges" of Neglected Zoonotic Diseases In many of the most affected countries the veterinary public health infrastructure is poor or nonexistent, leading to indecision ion as to which sector(s) ) should take responsibility for investigation and control of NZDs (i.e. veterinary/agriculture versus health) This situation has led to NZDs control falling into the gap between veterinary responsibilities and medical needs. Interventions to control NZDs require concerted action between veterinary, livestock and human health sectors and thus a comprehensive and integrated interdisciplinary approach is needed to address the major obstacles for effectively combating them.
To achieve success combating the NZDs Provide global and regional forums to promote One Health integrated approach Conduct and maintain inventories of control activities and tools Develop guidelines for implementing NZDs and other VPH- related activities Promote advocacy efforts to inform about NZDs and create demand for their control Develop and test practical, cost-effective surveillance and control strategies
Overview of ICONZ Activities and Work Packages WHO/OMS EU FP7-funded 5 year project on Integrated control of neglected zoonoses in Africa (ICONZ): improving human health and animal production through scientific innovation and public engagement Comprehensive and integrated approach to NZDs in the region most affected Involves 22 partner institutes in Europe and Africa (8) Major role to women Provide technology transfer and training to affected countries Inception meeting on 13-15 May 2009
