How is Dengue Spread ?
Dengue is spread when the femaleAedes
aegypti mosquito bites an infected person,
it sucks up the blood with the virus and
passes this virus onto the next person shebites for more blood. In this way the
mosquito becomes a carrier of the dengue
virus. We call these carriers of diseaseand illness vectors

How can we prevent Dengue from
spreading?
There is no vaccine to protect us from
Dengue.
We must, therefore, protect ourselves by
avoiding the infection. The only way of
becoming infected is through the bite of
the mosquito that is carrying the virus.

avoid mosquito bitesTheAedes aegypti mosquito that carries the dengue virus,
likes to lay her eggs in water near or in our homes. Sheenjoys living near to humans, her convenient bloodsupply.
Anything that holds water can be a mosquito-breeding site.Therefore, the best way of protecting your family andcommunity from dengue fever is to destroy all the placesin which the mosquito can lay eggs, breed more youngmosquitoes, increase their number, and so spread
dengue to more persons when they bite them for theirblood. Here are some actions you can take to rid yourhome and community of mosquito breeding sites.

Community & Government -
Partners in Dengue Prevention
Every government takes the responsibility for keeping public placesfree of garbage and junk that can become mosquito-breedingplaces. Your Government provides us with information on how wecan act to protect yourself, and assist us as much as possible.
But, no Department of Health, no government, can come into ourhomes and workplaces and stop mosquitoes from biting us. Only wecan do this. The government cannot stop the mosquito frombreeding in our flowerpots or debris left strewn in our yards. Only wecan do this.
If we are serious and determined, we can ensure that mosquitoes haveno place to breed more mosquitoes to bite us and give us dengue
fever.So Search and Destroy mosquito breeding places at home and work
