This paper evaluated the epidemiological situation of the enzootic bovine leucosis from 1995 to 2005, in Portugal. With exception of the South region, Algarve, the disease was distributed throughout the country, being more prevalent in the north, between Douro and Minho and Trás-os-Montes, than in the centre. A decrease in prevalence and incidence of the infection throughout the studied period was also observed.
