PREVENTION

AND

CONTROL

- an infectious

tropical disease caused

by the dengue virus,

transmitted thru a bite

of a mosquito by the

genus Aedes.

What is Dengue?

DISTINCT PHYSICAL FEATURE

-black and white stripes on its body and legs

Aedes aegypti mosquito

CLOSE – UP LOOK

Lays its eggs in clean,

stagnant water

Only the FEMALE Aedes

LIFE CYCLE OF A MOSQUITO

EGGS- Black and oval in shape- Laid singly above watersurfaces of containers

LARVA:- Feeding stage

- Breeds in clean and non-polluted

water

- Short and stout siphon with one

pair of hair tuft

- Rests at an angle to the water

surface

Pupa

-Non-feeding stage

-Breeding trumpet is long,

slender with narrow

opening

Adult

-Maxillary pulps shorter than

proboscis

-Wings uniformly grayish black

-Body and legs are black with

distinctive white patches

throughout

-Thorax has markings

Life Cycle cont’d

Transmission of Dengue

Humans become

host of virus.

Incubation is 4-10

days then produce

dengue symptoms

Humans get infectedfrom bite of infectedmosquito. Mosquitosget infected when theybite infected humans.

Mosquito bites and sucks

blood containing the virus

from an infected person.

Virus is carried in its

body.

And passes the virus to

healthy people when it

bites them.

SYMPTOMS

Dengue Hemorrhagic Fever: High fever, hemorrhage, has 4 grades:

Grade 1:

Fever, non specific

Grade 2:

Grade 1 manifestation +

spontaneous bleeding

Grade 3:

Signs of circulatory failure

Grade 4:

Profound shock, death

No commercially availablevaccine.

Prevention and control are sought by reducing

the habitat, controlling the number of

mosquitoes, and limiting exposures to bites.

CHILDREN ARE AT GREATER

RISK than adults because

they are unable to recover

from the bleeding during

the SHOCK PHASE.

COMMON BREEDING PLACES
