Rabies in Bali: A chronology and experience made with an EcoHealth approach for a better control of rabies Presentation Transcript

  • 1. Rabies in Bali ‐ a chronology and experience made with an  EH approach for a better control of Rabies Fred Unger ILRI Training provided to WHO fellowship trainees from Sri Lanka  on “Health approaches for rabies control and control of other zoonotic  diseases”. Faculty of Veterinary Medicine, CMU, Chiang Mai, Thailand,  20 May 2013. 
  • 2. Structure of presentation 1. Rabies in Indonesia and Bali – Background and chronology 2. EH/OH approach 3. Eco ILRI project Optimizing Rabies Control Program in Bali: An Ecohealth Approach
  • 3. History of rabies in Indonesia • First reported in buffalo in 1884 (Esser) • First case in dog was reported in 1889 (Penning) and in human in 1894 (de Haan) • Known to occur in West Java • Since 1948 documented spread to other parts of Indonesia • By 2011, reported 23 of 33 provinces (Ditkeswan, 2011). • Bali is the 24th province, since December 2008 Before, it was historically free.
  • 4. History of rabies in Indonesia
  • 5. Island of Bali 
  • 6. Bali background  5,636.66 km2 or 0.29% of the total Indonesian archipelago  3,741,952 people, 479 people per km2  Estimated dog population approx. 500,000++  Religion Hindu (87%)  8 Districts + Denpasar  Political structure: Governor of Bali  Economy from tourism and agriculture
  • 7. Rabies Bali ‐ Chronology   21 Nov 2008 DIC Denpasar informed from local authorities about a increase of dog bites in Badung District, Ungusan village and the dead of 3 yr old boy  Boy had history of been bitten by dog on 19 Oct 2008  Dog appeared healthy but was killed by the family  2 more people died with history of dog bites (17 Sep & 14 Nov 2008) with encephalitis like symptoms  Investigation showed increased dog bites in the village but no evidence of rabies in dogs  Villagers ordered to tied up their dogs after bitten somebody
  • 8. Rabies Bali ‐ Chronology  The first confirmed human case 23 November 2008 • a 28-year-old male from Ungasan died with a bite history from a stray dog (not found) on 16 September. FAT Bbalitvet Laboratory in Bogor confirmed Rabies.
  • 9. Rabies Bali ‐ Chronology  The first confirmed animal case 26 November 2008 • a dog bite case was reported from Banjar Pengenderan, Kedonganan village, Central Kuta. • A three-year-old child was bitten by a dog that had shown abnormal behavior and had died a few hours after the biting incident. The child received PEP and the dead dog was diagnosed rabies
  • 10. Rabies Bali ‐ Chronology  • Apart from the four human rabies cases (three based on clinical symptoms with dog-bite histories and one confirmed), health services shared history of a further suspected human rabies case. The individual had been bitten by an un-owned dog in July 2008. • Suggest that the rabies virus could have been introduced in the first half of 2008 and gone undetected in the animal population until its diagnosis in humans
  • 11. Rabies Bali ‐ Chronology  Government response • Mass vaccination in Badung District • Dec 2008 until Feb 2009, 1st campaign • 16,700 vaccinated dogs, estimated 35% of dog population in this district • Call for elimination of stray dogs (strychnine) critiqued by international press and its appropriateness with regard to animal welfare and effectiveness questioned.
  • 12. Studied Districts = observed villages
  • 13. Rabies Bali ‐ Chronology  • .
  • 14. Rabies Bali – First outbreak foci • .
  • 15. Rabies Bali ‐ Chronology  • Rabies managed to spread north • In 2009 and 2010 there was a significant increase in dog bite cases. • By October 2010 the Ministry of Health announced 56,259 bite cases in Bali with 168 human fatalities. • Largest case of zoonotic disease outbreak ever reported for Bali (e.g. AI only been 6 human fatalities)
  • 16. Rabies Bali ‐ Chronology  • With the spread of rabies beyond Badung Prov Gov ordered an island-wide stray dog elimination and mass vaccination program. • Target was to eliminate 20% and vaccinate 80% of the dog population in Bali. • Due to limited government resources only managed to vaccinate 260,000 dogs and revaccinated 115,000 dogs by October 2010 • Dog population estimates 2-3 times higher • No accurate information on dog population • Dog elimination heavily criticized by international media
  • 17. Rabies Bali – Dog elimination ‐ Mass media  Rabid Dogs Kill 78 in Holiday Hotspot of Bali Published August 02, 2010, Associated Press Read more: http://www.foxnews.com/travel/2010/08/02/rabid‐ dogs‐kill‐holiday‐hotspot‐bali/#ixzz2Tk5mr8oC CBS/AP/ August 2, 2010, 10:07 AM  Killing 200,000 Dogs Doesn't Halt Rabies in Bali MORE ABOUT RABIES ‐ WHY KILLING DOGS DOESN’T STOP  THE VIRUS http://www.baliadvertiser.biz/articles/greenspeak/2010/killing_ dogs.html Collars not cruelty in Bali: Saving street dogs from strychnine http://www.wspa‐international.org/red‐collar/case‐ studies/#.UZjMKsof2nY
  • 18. Rabies Bali ‐ Challenges • Limited government resources and coordination • Lack of information crucial for a vaccination program: • Dog population unknown or imprecise estimates, varies from 400,000 to 800,000 • Population dynamics? • Majority of dogs un-restrained, exact ratio between retrained/unrestrained/not owned dog • Underlying social cultural believes
  • 19. Rabies Bali ‐ Challenges • Rabies control cannot left with government alone • Communities needs to be involved • People of Bali is a unique community that has its own  unique relationship with the animals around it • Alternative approaches are required – multi-sectoral, across disciplines and institutions such as EH or OH
  • 20. Eco Health & One Health versus classical sector approach
  • 21. Eco Health & One health Ecosystem approaches to public health issues acknowledge the  complex, systemic nature of public health and environmental  issues, and the inadequacy of conventional methodologies for  dealing with them.  David Walter‐Toews, University of Guelph  One Health is the collaborative effort of multiple disciplines  working locally, nationally, and globally, to address critical  challenges and attain optimal health for people, domestic animals,  wildlife, and our environment  One Health Commission (http://www.onehealthcommission.org/ ) 
  • 22. Introduction: Ecohealth Theory • Based on 6 principles: • • • • • • Systems thinking Knowledge to action Transdiciplinary Participation Equity  Sustainability • 4 interacting sub‐ systems influence  health Social Economic Political Ecological An approach to understand complex systems (socio‐economic, socio‐ ecological ect) 
  • 23. Introduction: Ecohealth Practice • System thinking:  System thinking suggests that the way to understand a  system is to examining the linkages and interactions between the  elements that make up the system.  • Knowledge to action: Knowledge to action refers to the idea that  knowledge generated by research is then used to improve health and  well‐being through an improved environment.   • Transdisciplinarity   inclusive vision of health problems by scientists from  multiple disciplines, community and policy actors  • Participation aims to achieve consensus and cooperation within   community and scientific and decision‐making groups; • Equity involves analyzing the respective roles of men and women, and  various social groups; • Sustainability:  ecohealth research should aim to make ethical, and  lasting changes which are environmentally sound & socially acceptable.

Quotes of Community Opinion “I am glad to see my son  can care of his dog more  better, even telling her  parents and people  around him to take care  the dogs responsibly.  Socialization to children  is important and already  seen results, it needs to  be continued” (I Wayan Subur – Banjar Bayad, Ds.  Melinggih Kelod ;  Evaluasi &  Monitoring  Meeting , Mar 12) “Socialization to school  children has given benefits  in our community. Please  continue . Equipped with  visual media or  impressions of events,  because such a community  in banjar% u2013 they will  care more about having  seen film rabid“ (I Nengah Suparta– Banjar Dukuh, Ds.  Sibetan ;  Dialog Desa – Aug 12 Source: CIVAS
  • 58. Next Plan • Result presentation to government (provincial livestock  services) – advocation & legitimation • Paper & Film Publication • Phase II: To implement programs which are designed  based on results of the first phase, such as: • Programs include: • Further public awareness • Community‐based dog registration • Community‐based rabies vaccination
  • 59. Conclusions – Perspectives ‐ Challenges • Information on dog ecology information could be used in  general for Indonesia, but should be adjusted to the local  context • Described social cultural characteristics are specified for  each local area (e.g. Bali VS. Kalimantan or Flores) • Used community  engagement  for a better rabies control  was able to have a wide outreach  • Only conventional approach to control rabies has failed  to be successful in Bali • Demonstrated integrated approach can help to make  needed conventional approaches more effective • Sustainability !
