In the western countries, the principal vectors (transmitters) are wild animals - especially bats, foxes, skunks, raccoons and the like, but due to a lack of dog vaccination and control programmes, dogs remain the major vector in Third World countries. Other common vectors are domestic cats, jackals, mongooses and, particularly in countries in western Asia, wolves. However, the range of infected animals in Third World countries is so wide (including livestock and rodents) that rabies should be suspect in any animal bite.
Although in terms of the traditional measures of incidence and mortality in man, rabies cannot be considered an important disease in comparison with many other conditions, the economic costs of rabies cannot be neglected. First, even where incidence is zero, significant and continuing costs are incurred for the surveillance and prevention of outbreaks, such as quarantine regulations, publicity campaigns and the investigation of persons exposed outside the country. Second, sizeable resources are committed in many countries to control the incidence and spread of infection among animals, both domestic and wild. Third, in infected areas there may be significant indirect costs, whereby the presence of rabies lowers the national income from tourism and various forms of agriculture, because of fear of infection.
Rabies has almost been eradicated within the European Union and future efforts will concentrate on vaccination of foxes in the few remaining infected areas. The success of the campaign can be judged, for example, from the fact that in the most infected Member State (Germany) only 108 cases have been reported in 1998 compared to 855 in 1995 and 3534 in 1991. The objective of the campaign is to eliminate the threat to humans and animals and to allow people to have a more intimate safer contact with nature. It will also contribute to dismantling quarantine for pets when they and their owners travel to the United Kingdom or Ireland (the pilot pet passport scheme began in January 2000). It can be confidentially expected that rabies will be eliminated from the EU within the not too distant future. The year 2000 programmes include 2.9 million euro towards the continuation of this campaign.
