Abstract

The introduction, implementation, successes and failures of multidrug therapy (MDT) in all Hansen’s disease endemic countries are discussed in this paper. The high efficacy of leprosy treatment with MDT and the global reduction of prevalence led the World Health Organization, in 1991, to establish the goal of elimination of Hansen’s disease (less than 1 patient per 10,000 inhabitants) to be accomplished by the year 2000. Brazil, Nepal and East Timor are among the few countries that didn’t reach the elimination goal by the year 2000 or even 2005. The implications of these aspects are highlighted in this paper. Current data from endemic and previously endemic countries that carry a regular leprosy control programme show that the important fall in prevalence was not followed by the reduction of the incidence. This means that transmission of Mycobacterium leprae check for this species in other resources is still an issue. It is reasonable to conclude that we are still far from the most important goal of Hansen’s disease control: the interruption of transmission and reduction of incidence. It is necessary to emphasize to health managers the need of keeping Hansen’s disease control activities to better develop control programmes in the future. The recent international proposal to interrupt the transmission of leprosy by the year 2020 seems to unrealistic and it is discussed in this paper. The possibility of epidemiological impact related to the human immunodeficiency virus/Hansen’s disease coinfection is also considered.
