BASIC FACTS ON DENGUE
(a) How dengue spreads?
Dengue is spread by the bite of an infected mosquito Aedes aegypti. The
mosquito gets the virus by biting the infected persons. The first symptoms of the
disease occur about 5-7 days after an infected bite.
There is no way to tell if a mosquito is carrying the dengue virus.
Therefore, people must protect themselves from all mosquito bites.
(b) Where does the mosquito live?
The mosquito rests indoors, in closets and other dark places. Outside,
they rest where it is cool and shaded. The female mosquito lays her eggs in
water containers in and around homes, schools and other areas in towns or
villages. These eggs become adult in about 10 days.
© Where does the mosquito breed?
Dengue mosquitoes breed in stored exposed water collections. Favoured
breeding places are:
Barrels, drums, jars, pots, buckets, flower vases, plant saucers, tanks,
discarded bottles, tins, tyres, water cooler, etc. and a lot more places where rainwater
collects or is stored.
