  • Title: Human rabies focusing on dog ecology-A challenge to public health in Sri Lanka.
    Author: Kumarapeli V, Awerbuch-Friedlander T.
    Journal: Acta Trop; 2009 Oct; 112(1):33-7. PubMed ID: 19540826.
    Abstract:
    Sri Lanka is among the top ten countries in the world that report the highest rate of human rabies deaths (2.8 per 1,000,000 in 2007) and animal bites requiring anti-rabies post-exposure treatment (PET) (755 per 100,000 in 2003). Dogs are the main reservoir and transmitters of rabies in Sri Lanka. Present study evaluates the effectiveness of dog rabies control strategies on reducing incidence of human rabies deaths. Analysis is based on data from last three decades and showed strong correlations between the interventions and human rabies incidence. GIS maps provided a method for illustrating the district distribution of human rabies deaths and dog population density and for recognizing districts at risk. Interrupting the natural transmission cycle of rabies in dogs would be a logical approach in eliminating dog rabies in Sri Lanka. However, interventions implemented so far, such as dog vaccination, elimination of stray dogs (abandoned in 2005), and animal birth control have been inadequate to do so. Better understanding of the ecology of stray and owned dogs (e.g. population density, population structure, confinement status) in the context of the human environment and culture, are needed to strategize the control activities, requiring coordination among regional Public Health and Veterinary services.
