Dengue fever has been on the rise in Malaysia over the past 40 years. It is a virus-caused disease spread by the bite of the Aedes Aegypti mosquito and is more prevalent in urban areas.
There were 43,346 cases and 92 deaths in 2013, a sharp increase from 2012 but fewer than 2008 when there were 49,335 cases reported. Selangor, Melaka, KL and Johor were the worst affected states.
While dengue fever is rarely fatal, if left untreated it can develop into hemorrhagic fever stage which has a far higher fatality rate.
Symptoms of dengue are summarised in this graphic.
There are no preventative vaccines in use in Malaysia at present and the best way to combat the disease is to empty flower pots and other stagnant water pools near the home where the mosquito likes to lay its eggs. Wear loose fitting, light coloured clothes and apply mosquito repellent on exposed skin.
