ABSTRACT
Introduction Leprosy, an infectious disease caused by
Mycobacterium leprae, affects the nervous system, skin, internal organs, extremities and mucous membranes. Biological, social and environmental factors influence its occurrence and transmission. The first effective treatments appeared in 1930 with the development of dapsone, a sulfone. The main components of a control and elimination strategy are early case detection and timely administration of multidrug therapy.
Objectives Review the history of leprosy control in Cuba, emphasizing particularly results of the National Leprosy Control Program, its modifications and influence on leprosy control.
Evidence Acquisition The historiological method was applied using document review, complemented by interviews with experts on leprosy and its control. Archived documents, medical records, disease prevalence censuses conducted since 1942, and incidence and prevalence statistics for 1960–2015 from the Ministry of Public Health’s National Statistics Division were reviewed. Reports and scientific literature published on the Program and the history of leprosy in Cuba were also reviewed.
Development Leprosy has been documented in Cuba since 1613. In 1938, the Leprosy Foundation was created with ten dispensaries nationwide for diagnosis and treatment. The first National Leprosy Control Program was established in 1962, implemented in 1963 and revised five times. In 1972, leper colonies were closed and treatment became ambulatory. In 1977, rifampicin was introduced. In 1988, the Program instituted controlled, decentralized, community-based multidrug treatment and established the criteria for considering a patient cured. In 2003, it included actions aimed at early diagnosis and prophylactic treatment of contacts. Since 2008, it prioritizes actions directed toward the population at risk, maintaining five-year followup with dermatological and neurological examination. Primary health care carries out diagnostic and treatment activities. The lowest leprosy incidence of 1.6 per 100,000 population was achieved in 2006. Since 2002, prevalence has remained steady at 0.2 per 10,000 population. Leprosy ceased to be considered a public health problem in Cuba as of 1993. In 1990–2015, 1.6% of new leprosy patients were aged ‹ 15 years. At present, late diagnosis of cases exceeds 20%, which leads to a high percentage of grade 2 disability in such patients. Spontaneous physician visits by already symptomatic patients surpassed 70% of cases diagnosed in 2010–2015.
Conclusions Actions undertaken after initial detection of leprosy in Cuba failed to control it. Effective control began in 1963, with the implementation of the National Leprosy Control Program, whose systematic actions have had an impact on trends in leprosy, reflected in WHO’s 1993 declaration that leprosy was no longer a public health problem in Cuba.
