  15. 15. ……….obstacles for Aedes Mosquito control. Present- Present-day Aedes Mosquito control programs are not progressing because: Community participation in dengue prevention and control is limited to official demands and never attains community ownership; 15 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  16. 16. ……….obstacles for Aedes Mosquito control. Local health services, now politically and administratively responsible for the d i i t ti l ibl f th prevention and control programs are not sufficiently established; 16 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  17. 17. ……….obstacles for Aedes Mosquito control. Individual and community behavioral change strategies are b h i l h t t i weak and are not incorporated into the programs; 17 Dr.G.C.Sahu/ROH&FW/GoI/A'bad

  19. 19. ……….obstacles for Aedes Mosquito control. Sustainability and continuity of control actions are constantly compromised by other health demands and policies that compete with them; 19 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  20. 20. ……….obstacles for Aedes Mosquito control. Little capacity for intersectoral coordination… The VBDCP/Mosquito problem is not the sole responsibility of the p y Dept of Health. 20 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  21. 21. ……….obstacles for Aedes Mosquito control. Operational research on individual or community-based strategies have community-y g not been sufficient. 21 Dr.G.C.Sahu/ROH&FW/GoI/A'bad

If citizens going on a holiday or keep their houses closed for a long time….. •Seal off all floor and •Cover all toilet bowls gully traps Leave your contact number with your neighbor so that the corporation authorities c n c rp r ti n uth riti s can contact you should there be a need to inspect your premises 35 urgently. Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  36. 36. What we should be doing……. Adult vector control in urban areas. Chemical fogging shall be periodically carried out in the urban areas where there is a potential risk for the transmission of the diseases.. Proper sanitation including community toilets and drainage facilities should be provided in the slum areas. Bio- Bio-environment control shall be carried out in urban areas to control mosquito menace. 36 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  37. 37. What we should be doing……. Promoting the use of larvae eating fishes for control of mosquito breeding. Introducing larvae eating fishes Larvae eating fish Gambusia fish, which eats larva of the mosquito, shall be grown in all water bodies/ lakes/ ponds / over head tanks 37 Dr.G.C.Sahu/ROH&FW/GoI/A'bad

  40. 40. What we should be doing……. Main Types of Adaptive Strategies • Public education and awareness • Early- Early-alert systems: impending weather extremes, heatwaves; infectious y y p g , ; disease outbreaks • Community- Community-based neighbour-support/care schemes neighbour- • Mosquito- Mosquito-proofed housing design … and ‘cooler’ urban layout • Disaster preparedness, incl. health-system ‘surge’ capacity health- • Enhanced infectious disease control programs • vaccines, vector control, case detection and treatment • Improved surveillance: • Risk indicators (e.g. mosquito numbers, aeroallergen concentration) • Health outcomes (e.g. inf dis outbreaks, rural suicide rates, seasonal asthma peaks) • Rural health services, counselling and community strengthening , g y g g • Appropriate (esp. health) workforce training, mid-career development mid- 40 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  41. 41. What we should be doing……. Strengthening the implementation of the g g p social- social-communication component in the state/national program. Promote the behavioral change focus so that it will be more than just dissemination of information. 41 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  42. 42. What we should be doing……. Solid Waste Management. Management. All the municipal waste should be collected from dust bins etc., and transported to the composting/land fill sites etc. p p g for treatment and disposal in order to avoid breeding of flies, mosquito etc. etc. The solid waste should be transported in covered vehicles so as to prevent littering of the waste on streets, roads etc. etc. Likewise, hospital Lik i h i l waste and bi -medical waste should b d bio bio- di l h ld be separately collected, treated and disposed in order to prevent breeding of mosquitoes, flies etc. p g q , etc.
  43. 43. What we should be doing……. Dead animals, carcasses should be removed immediately and buried under land fill sites and properly covered with soil to prevent breeding of mosquitoes and flies. flies. Public P bli awareness on environmental cleanliness i t l l li may be created through IEC and mass media. media. Under JNNURM there is provision to formulate schemes, drainage and solid waste management simultaneously and incorporate g y p the same in the City development Plan (CDP) (CDP) to make the environment free from vector menace. menace.

Social d S i l advocacy i fin favor of f intra- intra- and intersectoral actions to minimize environmental health problems (water and solid waste management). 44 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
  45. 45. What we should be doing……. Social- Social-Communication Component It is not a “magic bullet” that can g stop Aedes mosquito breeding. A person achieves behavioral changes in steps. There is a need steps. to go from one phase to another sequentially. sequentially. 45 Dr.G.C.Sahu/ROH&FW/GoI/A'bad
