5. VIRUS
Scientific name: Dengue virus
Family: Flaviviridae
Class : Amarillovirales
Kingdom: Orthornavirae
Higher classification: Flavivirus
Dengue virus is the causes of
dengue fever. It is a mosquito
brone, single +ve standed RNA
virus.

8. TRANSMISSION
•Dengue is transmitted by several species of
mosquitoes within the genus Aedes,principally
Aaegypti.
•Dengu virus is primarily transmitted by Aedes
mosquitoes, particularly A.aegypti.
•These mosquitoes live between the latitudes of
35°North and 35°South below an elevation of 1000
meters (3300 ft).They bite primarily during the day.

9. ther Aedes species that transmit the disease include
A.albopictus, A.polynesiensis and A.sutellaris.
Humans are the primary host of the virus.
An infection can be acquired via single bite.
A female mosquito that take a blood meal from person
infected with dengue fever becomes itself infected with
the virus in the cell lining its gut.
About 8-10 days later,the virus spread to other tissue
including The mosquito salivary gland and is
subsequently released in saliva.

outside of your home

22. WORLD HEALTH ORGANIZATION RECOMMENDS
AN INTEGRATED VECTOR CONTROL PROGRAM
CONSISTING OF FIVE ELEMENTS
1. Advocacy, social mobilization and legislation to
ensure that public health bodies and communities
are strengthened
2. Collaboration between the health and other
sectors (public and private)
3. An integrated approach to disease control to
maximize use of resources

23. 4. Evidence-based decision making to ensure any
intervention are targeted appropriately and
5. Capacity-building to ensure an adequate
response to the local situation.
