“…[1,2] The rationale is grounded in the foundations of Cuba's National TB Control Program (PNCT, the Spanish acronym), established at the fi rst meeting of tuberculosis hospitals and dispensaries in 1961 and in the fi rst National Forum on Public Health and Epidemiology in 1962, leading to drafting the Program's guiding document in 1963, the year PNCT implementation began. [3] In 1965, the case notifi cation rate for TB (all forms) was 65 per 100,000 population; it steadily declined to 4.7 per 100,000 in 1991, rose to 14.5 per 100,000 in 1994 [3][4][5][6][7] and again declined steadily to under 10 per 100,000 in 2006-2010, accompanied by a decline in mortality rates. [6][7][8] However, when new case notifi cation and mortality rates reached 7 and 0.2 per 100,000 population, respectively, [3,4] some of PNCT's usual indicators became inadequate for monitoring and evaluation of program processes and impacts.…”
