Neglected tropical diseases

Some figures on the impact of neglected zoonotic diseases

  • In today's world the rural poor represent 911 million people, of which 411 million are poor livestock-keepers (almost half in south Asia and one-third in sub-Saharan Africa).

  • At least 55 000 people are dying of rabies in Asia and Africa, and expenses related to the prevention and control of this disease is estimated at US$ 590 million annually on these two continents.

  • The total cost of an average rabies post-exposure prophylaxis course is US$40 in Africa and US$49 in Asia. This amounts to a substantial fraction of per capita Gross National Income (5.8% in Africa and 3.9 % in Asia).

  • The annual societal cost (agriculture and health) of porcine cysticercosis/taenosis is estimated at about US$150 million in India alone.

  • On the Tibetan plateau, the annual combined human and animal losses due to echinococcosis equate to approximately US$3.47 per person or 1.4% of per capita gross domestic product.

  • Echinococcosis in Tunisia causes significant direct and indirect losses in both humans and animals of between US$10 million and US$19 million annually. The reported incidence in humans is 1.5 to 2.05 cases per 100 000 inhabitants and between 12% and 17 % of the cattle at slaughter is found to be infested.

  • Disability-adjusted life years (DALYs) and monetary losses resulting from human and livestock cystic echinococcosis have been calculated at the global level assuming substantial under-reporting. The estimated global human burden of echinococcosis may be as high as 1 009 662 DALYs - or an annual loss of US$ 763 980 979. A maximum annual livestock production loss of US$ 2 190 132 464 is also estimated.

  • More than 50 000 cases of human brucellosis were diagnosed in only eight countries located south and east of the Mediterranean Sea in 2003.
