Where does the Aedes Mosquito breed?
|
|
A puddle of water about the size and depth of 20-cent coin is sufficient for an Aedes mosquito to breed in.
The Aedes mosquitoes are commonly found breeding in clear stagnant water in flower vases, flower pot plates, roof gutters, earthen jars for water storage or decorative purposes, watering cans, and bamboo pole holders.
The Aedes mosquito can also breed in unusual places such as water trapped in the hardened soil in potted plates, and the rim of unwanted pails.

How is Dengue Fever spread?
|
|
Dengue fever is spread through the bite of the Aedes mosquitoes. It is not spread from one person to another.
The transmission cycle for dengue starts when:
Infected Aedes mosquito bites a healthy person.
4-7 days later, the infected person develops fever (after the virus multiplies i.e., incubation period). The person usually then sees a doctor.
When fever starts, the person becomes infectious for about 5 days.
If an Aedes mosquito bites the person during this period when he is infectious, it will pick up the dengue virus in his blood.
The virus takes 7-10 days to multiply in the second mosquito.
The mosquito then becomes infective and the cycle starts again when it bites another person.
An infected person does not spread the virus to another person directly but he becomes a source of dengue virus for the Aedes mosquitoes.

What is Dengue Fever?
|
|
Dengue Fever and dengue haemorrhagic fever (a more severe form) are the most common mosquito-borne viral diseases in the world.
Dengue fever is an illness caused by the Aedes mosquito. There are four types of dengue viruses (serotypes 1 to 4).
If you get a second dengue infection (from another mosquito bite), you could get Dengue Haemorrhagic Fever and Dengue Shock Syndrome, which can be fatal.
