Vector of Dengue Fever

Important vectors of disease transmission in the DHF is the mosquito Aedes aegypti. This mosquito is genus Aedes, including Tribe Culicini, family Culicidae (Mosquitoe), ordo Diptera. Aedes aegypti life cycle has metamorfosis complete, in which there are 4 stages of its development, namely eggs, flyblow, chrysalis, adult. Cycle Maintenance mosquitoes ranged between 10-12 days

Larva of Aedes mosquitoes usually lay eggs in water that cool and clean, such as flower pot, crock, and so forth. Aedes aegypti doesnt like grubby or dirty place,. Places preferred by this mosquito is a crock or a place that is open water, bathtub, water holes on the rain gutter or street clean, pot plants or flowers that filled water, the cans used to be rain water, and other.

Adult mosquitoes look brown-black strip with a strip of white contrast in the abdomen, thoraks and ekstremity. There is a sign of characteristics in adult Aedes aegypti mosquitoes that can be used as a criterion to distinguish the species Aedes other, which is "Marking Lyre" (a description of silvery white strip at the dorsal than thoraks, and white color on the last segment of the back foot ).

Aedes aegypti has habits "day biter" (suck up food on the day), especially young mosquitoes (age 1-8 days). The old age, tend to change the habit to "night biter" (suck up food on the night)

trasmission cycle

These next two slides review the transmission cycle in more detail. This slide represents the part of the transmission cycle that takes place within the human body.

1. The virus is inoculated into humans with the mosquito saliva.
2. The virus localizes and replicates in various target organs, for example, local lymph nodes and the liver.
3. The virus is then released from these tissues and spreads through the blood to infect white blood cells and other lymphatic tissues.
4. The virus is then released from these tissues and circulates in the blood.
