Dengue - Preventing dengue

There is no vaccine to prevent dengue. The best way to prevent getting the disease is to avoid being bitten by an infected mosquito.

Avoid being bitten by a mosquito by:

  • using insect repellent to avoid being bitten, especially around dawn and dusk  products containing N-diethylmetatoluamide (DEET) are effective, but products containing this ingredient should not be used in babies younger than two months and in lower concentrations in younger children (20-30% DEET)
  • wearing loose-fitting but protective clothing  mosquitoes are able to bite through tight-fitting clothes; trousers, long-sleeved shirts, and socks and shoes (not sandals) are ideal
  • sleeping under a mosquito net to avoid being bitten at night
  • be aware of your environment – mosquitoes that cause dengue breed in standing water in crowded urban environments; this can range from communal toilets to water that gathers inside a stack of old tyres
