Echinococcosis: costs, losses and social consequences of a neglected zoonosis.

The socio-economic impact of echinococcosis, with special reference to cystic echinococcosis (CE) caused by Echinococcus granulosus, is reviewed. The following items are discussed: socio-economic consequences in humans; economic consequences in livestock; costs and benefits of control programmes; economic evaluation of control programmes; social reasons favouring the life cycle of CE; social, political and economic situations hindering the control of echinococcosis. Many consequences are difficult to evaluate from an economic point of view. However, many evaluations have shown that CE is an important (often neglected) public health and economic problem, especially in endemic areas, and that the socio-economic evaluation of its consequences and of control actions proves indispensable to best use available resources and possibly tailor control strategies.

[An insight into the epidemiology and economic impact of gastro-intestinal nematodes in small ruminants]. / Nematodi gastrointestinali dei piccoli ruminanti: note di epidemiologia ed impatto economico.

Milk production has been a distinguishing characteristic of sheep breeding since antiquity in the Mediterranean area, including Italy, where prehistoric findings confirm this particular husbandry activity. In Homer's Odyssey, the description of Polifemo's sheep flock organization is remarkably similar to current production systems. The ancient roots of this tradition have grown into an important economic reality, with excellent levels of milk production and apporoximately 65 typical cheeses. It is interesting to note that the Italian word "pecora" (sheep) is believed to have originated from the Latin "pecunia" (money). Although heavy production losses are due to parasitic infections, only 250 papers have been published in the last 50 years in Italy on sheep parasites. Differences in climate, environmental factors and production tecniques may influence infection prevalence, load and pathogenesis. For this reason, prevention must be aimed at the particular epidemiological situation and not simply adapted from current schemes used abroad. The aim of this paper is to illustrate the epidemiology of ovine gastrointestinal nematodes in Italy and to evaluate the economic importance of their control.

Socio-economic impact of cystic echinococcosis and of its control: some data and considerations.

The socio-economic impact of cystic echinococcosis (CE), caused by Echinococcus granulosus, is reviewed with special reference to the following topics: consequences in man and livestock, costs and benefits of control programmes and economic procedures for evaluating control programmes. Examples of some important costs and benefits are given. Many consequences in man and livestock are difficult to evaluate from an economic point of view, because some basic data are difficult to obtain in many countries. However, the socio-economic evaluation of the consequences of CE and of the present and future control actions proves indispensable to best use available resources and possibly tailor control stategies.

Cystic echinococcosis and the Mediterranean Region: a long-lasting association.

Cystic echinococcosis (CE) is an important zoonosis in Italy and in the whole Mediterranean Region, as confirmed by the work by Ettore Biocca, whose contributions to the subject are reported in a summarised annex to the bibliography. The contribution to the understanding and control of CE are presented, with special emphasis on the socio-economic impact, on factors affecting the maintenance of CE in the Mediterranean Region, on the epidemiological situation and control measures, on the present status of epidemiological surveillance, on the control problems in normal and emergency situations, on health education and training. Also, the justifications of combined control programmes are discussed, which may be applied only in situations of peace and well-being.

Echinococcosis/hydatidosis: socio-economic consequences and economic analyses of control programmes.

A review is made of the socio-economic consequences of echinococcosis/hydatidosis and of the methods of economic analysis of control programmes. The main costs and benefits (both financial and social) which should be taken into consideration in evaluating health action are also examined.
