Langford, C.MCaldwell, John C.Jain, Shail2003-03-042004-05-192011-01-052004-05-192011-01-051996http://hdl.handle.net/1885/41304http://digitalcollections.anu.edu.au/handle/1885/41304Newman estimated that 42 per cent of the decline in mortality in Sri Lanka between 1930-1945 and 1946-1960 was attributable to DDT-spraying; Molineaux estimated 27 per cent; Gray judged that 23 per cent of the decline between 1936-1945 and 1946-1960 was due to DDT. Here the Newman-Gray-Molineaux approach is criticized, the main point being that they ignored a significant improvement in mortality in the early 1940s, before DDT-spraying. Bearing this, and certain other complexities of the situation, in mind, an attempt is made to assess the impact of DDT on mortality.69039 bytesapplication/pdfen-AUSri Lankadecline in mortalitySecond World WarDDT sprayingmalariaadult mosquitospublic health1996
