Resumo
The objectives of this article were to discuss the
rapid spread of visceral leishmaniasis in urban
areas of Brazil and to raise practical questions
and perspectives related to control of the disease.
Among the proposed methods, the elimination of
seropositive dogs is the most controversial and
least accepted by society. Its impact on incidence
rates varies among studies (positive in some and
relatively unimportant in others). Treatment of
infected dogs, although widespread in veterinary
practice, is based on studies with weak scientific
evidence. Insecticide spraying of areas is more
acceptable to the population, but is costly and
operationally difficult. Intra and inter-urban
factors have scarcely been studied and may affect
control of the disease. Finally, the article discusses
the use of deltamethrin-impregnated dog collars
and vaccines, with high expectations for impact
on disease transmission, although no product
currently available on the market has been fully
evaluated, so that further studies are required.
