Dengue is spread by Aedes mosquitoes, so prevention is all about avoiding bites and stopping these mosquitoes from breeding around you.

Quick Scoop: How to Prevent Dengue

1. Kill the breeding spots (most important)

Aedes mosquitoes love clean, still water. Check your home and surroundings at least once a week:

  • Empty or remove items that collect water: old tyres, cans, buckets, bottles, broken pots.
  • Scrub and refill: flower vases, plant saucers, birdbaths, pet bowls at least every 2–3 days.
  • Cover water storage: tanks, drums, barrels should be tightly covered so mosquitoes cannot lay eggs.
  • Clean roof gutters and drains so water does not stand after rain.
  • Keep trash in closed bags and bins so containers don’t fill with rainwater.

Think of any place where rain or tap water can sit more than a few days—that’s a potential dengue nursery.

2. Protect your skin from bites

Because Aedes mosquitoes bite mainly during the day (especially early morning and late afternoon), daily personal protection really matters.

  • Wear long-sleeved shirts, long pants, socks and closed shoes when possible.
  • Prefer light-coloured clothing; mosquitoes are more attracted to dark colours.
  • Use mosquito repellent on exposed skin that contains DEET, picaridin, IR3535, or oil of lemon eucalyptus (follow age and label instructions).
  • Reapply repellent as directed, especially after sweating or washing.

Example: If you’re working near plants or water storage in the late afternoon, wear long clothing plus repellent on hands, neck, and face.

3. Make your home a mosquito barrier

Physical barriers reduce the number of mosquitoes that can reach you.

  • Install and repair window and door screens to keep mosquitoes out.
  • Use bed nets (preferably insecticide-treated) if you sleep during the day or live in a dengue-prone area.
  • Use mosquito-proof lids or fine mesh over water tanks and large containers.
  • Use coils, plug-in vaporizers, or indoor sprays responsibly if mosquitoes are present indoors.

If you have air conditioning and keep windows closed, indoor mosquito numbers usually drop.

4. Community actions (not just individual)

Dengue control works best when whole neighbourhoods take action together.

  • Join or support local clean-up drives to remove junk and containers where water collects.
  • Share information about dengue symptoms and prevention with neighbours, especially during rainy seasons when cases rise.
  • Cooperate with local health workers doing inspections, spraying, or larvicide treatment of water.

If even a few houses keep many breeding sites, mosquitoes can easily spread back into “clean” homes.

5. Vaccines and medical awareness

Some countries use dengue vaccines for certain age groups or people with previous dengue infection, but availability and recommendations differ by region.

  • Check with a local doctor or public health authority about whether any dengue vaccine is recommended where you live.
  • If someone has high fever, severe headache, eye pain, strong muscle or joint pain, or a rash after a mosquito bite, they should see a doctor quickly to rule out dengue or manage it early.

Early medical care cannot “prevent” infection you already have, but it can help prevent severe dengue complications.
