Some developed countries have networks advocating 'One Health' for combating
zoonoses, whereas inadequacies exist in developing nations such as those West African countries in which the current EVD epidemic is taking place.
The one health approach plays a significant role in the prevention and control of
zoonoses. It has been noted by the World Health Organization (WHO) [4] and Graham et al.
The lack of effective and sensitive surveillance systems combined with low awareness of the risks associated with
zoonoses contributes to a general under estimation of the importance of
zoonoses in developing countries (1-4).
From cyst-causing tapeworms to avian flu,
zoonoses present a major threat to human and animal health,' said Delia Grace, a veterinary epidemiologist and food safety expert with ILRI in Kenya and lead author of the study.
It also found the United States and Europe - especially Britain - Brazil and parts of Southeast Asia may be becoming hotspots of "emerging
zoonoses", which are infecting humans for the first time, are especially virulent or are becoming drug resistant.
The authors correctly described risk for Chagas disease from exposure to infected insect vectors but included Chagas disease in the table, "
Zoonoses acquired by close contact with pet, 1974-2010." The bloodborne protozoan that causes Chagas disease is transmitted not by contact with an infected mammal but by contact with a vector insect that has bitten an infected mammal (2).
Sob o ponto de vista economico, sua participacao e tambem relevante pelo impacto das
zoonoses tanto sobre a saude humana quanto animal.
Zoonoses are defined by the World Health Organisation as "Diseases and infections which are naturally transmitted between vertebrate animals and man".
Zoonoses are diseases that originate in animals but can jump species and infect humans.
Sixty per cent of them are so-called
zoonoses, or diseases that have been transmitted from animals to humans.
