Abstract:

ObjectiveTo evaluate the performance of the canine rabies surveillance system conducted in Chuxiong Yi Autonomous Prefecture, Yunnan Province from 2010 to 2013. Methods: Upon the occurrence of aggressive dog-attack incidents ADAI, medical intervention will be initiated to investigate the dogs and people involved. The dog brains were sampled and sent for laboratory testing using direct immunofluorescence assay and RT-PCR. The field investigation reports provided the material basis for the ADAI report surveillance systemARSS. Within 24 hours, the laboratory diagnostic reports were submitted to local authorities. Meanwhile, the non-ADAI dogs suspected with the signs of rabies were also sampled and tested. Based on the brain tissue specimens from ADAI and non-ADAI dogs, a lab-based canine-rabies case surveillance systemLab-CCSS was established. Results: From 2011 to 2013, a total of 89 ADAI reports were submitted; rural areas accounted for 94.38%. The sampling rate of ADAI dogs was 51.69% 46/89 and the positive rate was 91.30%42/46. The positive rate of the non-ADAI dogs sampled was 59.09%13/22. In ADAI, 336 people were potentially exposed to rabies and children 14 years of age were at the highest risk, accounting for 30.36% of the total, 80.00%8/10 of the head and face bites and 40.54%15/37 of multiple bites. Conclusion: ARSS has a high sensitivity in screening rabies dogs. The experience accumulated by Chuxiong Yi Autonomous Prefecture has significant reference value to establishing a canine rabies surveillance system inYunnanProvinceand even inChina.
