It is clear from the Results that the cases are increasing. However, the reader doesn't know the geography of this area. Is Bahr Zur district one of two districts? One of ten? If Bahr Zur district has 25% of the population, then we would expect them to have 25% of the malaria cases. This needs to be clear.  It also would have been nice to see the proportion of cases <5 years for each year. In my experience, 14% being <5 years is very low! Usually most of the cases are <5 years.
