Cost-effective malaria control in Brazil. Cost-effectiveness of a Malaria Control Program in the Amazon Basin of Brazil, 1988-1996.

摘要

Malaria transmission was controlled elsewhere in Brazil by 1980, but in the Amazon Basin cases increased steadily until 1989, to almost half a million a year and the coefficient of mortality quadrupled in 1977-1988. The government's malaria control program almost collapsed financially in 1987-1989 and underwent a turbulent reorganization in 1991-1993. A World Bank project supported the program from late 1989 to mid-1996, and in 1992-1993, with help from the Pan American Health Organization, facilitated a change toward earlier and more aggressive case treatment and more concentrated vector control. The epidemic stopped expanding in 1990-1991 and reversed in 1992-1996. The total cost of the program from 1989 through mid-1996 was US
