Dengue Fever Alert

Recently, over 20 citizens have been confirmed to be suffering from Dengue fever. They have been concluded by authorities as locally occurring cases. Dengue Fever is an acute mosquito-borne infection caused by the dengue virus. The dengue virus encompasses 4 different serotypes. Incubation period ranges from 3 to 14 days, commonly 4 to 7 days.

Dengue fever is clinically characterized by sudden onset of high fever, severe headache, pain behind the eyes, joint and muscle pain, loss of appetite, nausea and rash.

The symptoms of first infection are usually mild. Once recovered, immunity to that serotype of dengue virus will develop, but subsequent infections with other serotypes are more likely to result in more severe symptoms, often called Dengue Fever. Severe Dengue Fever may be fatal with hemorrhagic complications.

There is neither a vaccine to prevent nor medication to treat dengue. Hence, the most effective way to prevent dengue is to prevent mosquito bites and control mosquito populations.

We should, therefore:

  • Wear loose, light-coloured, long-sleeved tops and trousers;

  • Rest in air-conditioned or well-screened rooms;

  • Use aerosol insecticide indoor and use bed nets if sleeping areas are not air-conditioned or screened.

  • Use insect repellents containing DEET or Picaridin on exposed skin and clothing;
