The annual number of deaths from dengue disease increased from 45 in 2000 to 134 in 2010, although the case fatality rate (CFR) remained constant at 0•2–0•3%, with 0•63% reported for the year 2000 (Figure 3B, 3C) [3], [9], [12], [21]. The CFR for DHF was relatively high in the year 2000 (10•9%) and then ranged between 2•5 and 6•9% from 2001 until 2011, with an apparent decline from 2006 until 2011 (Figure 3C).
