RESUMO
Peste des petits ruminants (PPR) is a contagious viral disease of domestic small ruminants. It also affects wild ungulates but there are comparatively few studies of the incidence of natural infection, clinical signs and pathology, and confirmation of the virus, and in these species. In this article, we list the wild ungulates in which PPRV infection has been confirmed and summarize available information about the presentation of the disease, its identification, and impact of virus on wildlife populations. Considering recent reports of outbreaks by the World Organization for Animal Health (OIE), it is important to understand the transmission of this disease within wildlife populations in PPR endemic regions.

Since the mid 1990s the term transboundary animal disease (TAD) has become widely used for a group of major infectious diseases of livestock with important economic impact. This article explains why the term is so appropriate and examines the severe direct and indirect consequences these diseases have when they cross borders. The paper also looks at the control of TADs and how improved control and trade can take place without having to eradicate them.
