I want to know the answer to the following question:
How much did the National Malaria Protection Unit reduce malarial mortality by from 1998 - 2006?
All the background I'm provided with is that "The National Malaria Protection Unit of the Ministry of Health has registered tremendous improvements in reducing malarial mortality by as much as 85% and the number of cases by 92% between 1998 and 2006.". Is that enough to answer the question?
