Dengue mosquito Aedes aegypti:
Dengue virus is primarily transmitted by
Aedes mosquitoes, particularly A. aegypti. These mosquitoes usually live
between the latitudes of 35° North and 35° South below an elevation of 1,000
metres (3,300 ft). They typically bite during the day, particularly in the
early morning and in the evening, but they are able to bite and thus spread
infection at any time of day all during the year.
There are no approved vaccines for the
dengue virus. Prevention thus depends on control of and protection from the
bites of the mosquito that transmits it. The 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;
4. Evidence-based
decision making to ensure any interventions are targeted appropriately; and Capacity-building
to ensure an adequate response to the local situation.
