DENGUE

Protect yourself from mosquito bites and dengue

Dengue symptoms can include:

• Fever
• Headache
• Muscle and joint pains
• Nausea / vomiting
• Rash
• Hemorrhagic manifestations
If you have these symptoms, ask your physician to order a test for dengue.
========================================
Treatment:
• Rest, drink plenty of fluids
and consult a physician.

• Avoid pain relievers that
contain aspirin and non
steroidal anti-inflammatory
medications such as
ibuprofen. Acetaminophen or
paracetamol may be used.
================================================

If you have dengue:
• Avoid mosquito bites while you
have a fever.

• Don't let mosquitoes bite you. They
can infect other members of your
family with dengue after biting you.

• Use mosquito barriers until the fever
subsides, to prevent day-biting
mosquitoes from biting a sick person,
becoming infected, and then biting
someone else.

• Rest in a screened room or under a
bed net.

• Use insect repellents and spray
insecticide indoors if there are
mosquitoes.
================================================

Dengue is carried by the Aedes aegypti
mosquito, which can be found in the
home.

This mosquito lays its eggs on the walls of
water holding containers that are found
around the home. Eggs hatch when
submerged in water. Within 8 days the
mosquito can complete its life cycle from
egg, to larvae, to pupae and to an adult
flying mosquito.

To help reduce the mosquito population in
your community and the risk of exposure
to dengue, eliminate larvae that grow in
stored water.
==========================================

If you have mosquitoes in your house:

Eliminate or control
any containers
where the mosquito
can lay her eggs,
either by emptying
the water, covering
them or turning them upside down.

• Keep mosquitoes outside by fixing or
installing window and door screens.
Don't give mosquitoes a place to
breed. A small amount of water can
be enough for a mosquito to lay her eggs

• Look around every week for possible
mosquito breeding places. Empty water
from buckets, cans, pool covers, flower
pots and other items that aren't being
used. Clean pet water bowls daily. Check
if rain gutters are clogged. If you store
water outside or have a cistern, make sure
it's covered up. Encourage your neighbors
to do the same.


If you have problems with the water
supply in your area and you have to
store water:

• Wash the interior of containers with a
brush or sponge, to remove mosquito eggs
that might be present, before filling them
with water.
• Keep containers with water tightly sealed
so that mosquitoes can not get inside and
lay eggs. If you observe mosquito larvae,
empty the container to eliminate any
mosquito eggs.

In order to prevent the Aedes aegypti
mosquito from laying its eggs in
containers where you store water,

keep it covered.

correct

Remember that after the rain… there are more mosquitoes

Some mosquitoes lay eggs in the walls of
artificial (plastic, metal, glass) containers
with fresh water. Other mosquitoes prefer
dirty water in trenches or brackish water in
swamps to reproduce. In only one week
these eggs can hatch and grow into adult
mosquitoes.


Immediately after the rain, SEARCH for and
ELIMINATE all WATER accumulated in
containers and help your community to
PREVENT DENGUE.
