Dengue awr

  1. 1. • Vector borne viral disease• Caused by Dengue virus (4 serotypes)• Spread by Aedes mosquito bite •Aedes aegypti •Aedes albopictus• 2.5 billion at risk globally• 1.8 billion resides in Asia Pacific region• Highest mortality during initial period ofoutbreak
  2. 2.  Unplanned urbanization Poor water storage Un satisfactory sanitary conditions Trade and travel Increased population
  3. 3.  Active disease surveillance -Laboratory diagnosis -clinical classification DF,DHF/ DSS Information Exchange -network system for timely national and international cooperation Capacity building: training staff for -laboratory diagnosis -case management, doctors and nurses -vector surveillance and control
  4. 4.  Job description of surveillance staff  (Surveillance and Rapid Response Team, SRRT) Data generation & flow Data analysis & reporting Data utilization for action SRRT at hospital level also 5
  5. 5.  Standard case definitions Early Case detection (Tourniquet-Test etc) Effective triage system Specific admission & discharge criteria Strong referral system 6
  6. 6.  Standardized formats -on line Vector & habitat identification Vector monitoring indices Weekly vector surveillance Regular vector survey twice a year Special vector surveillance in high risk areas 7
  7. 7.  Source reduction (predominantly) Biological control (Bacillus thuringiensis israelensis, Bti & larvivorous fish) Chemical control (fogging , IRS, larvicide) Use of detergents at home Personal Protection ( Repellents, detergents, lemon extract etc) 8
  8. 8. Chemical Control• Adult control : mass fogging ofadulticide• Add temephos into all containersused for water storage.
  9. 9. Biological control• Larvivorous fish (guppy)• Bti(Bacillus thuringiensis israelensis)
