Since the first outbreak in the southern peninsula of Bali in November 2008, rabies quickly spread across the districts/municipality, until July 2015 had spread across 54 subdistricts and 263 villages. The proportion of rabies cases in the subdistricts and villages the highest occurred in 2011 is shown 94.7% and 36.7%, respectively, but its spread dropped dramatically in 2013 only occurred in 23 subdistricts (40.4%) and 38 villages (4,2%), though rabies outbreak back by increasing the number and distribution of rabies cases significantly in 2014, spread over 94 villages even until July 2015 spread over 89 villages. Rabies attacks the various breeds of dogs with the proportion of rabies in the local dogs showed the highest (98.44%), as well as the male dog, is very significantly higher than female dogs. By age group, the proportion seen in the age group of 1 to 2 years showed the highest (39.9%). Other animals, such as cats, cows, goats, and pigs have also contracted the rabies infected dog bitesthe . The incidence of rabies is endemic tend to look at some of the same villages actively repeated every year, most occur in Bangli district (29 villages), nevertheless for 3 consecutive years there were 58 villages there are no cases of rabies. The increasing number of cases of rabies in Bali due to the increasing cases of dog bites, since May 2008 to July 2015, there were 274 792 cases, an average of 34 349 cases per year, or 95 cases per day, the highest occurred in 2010 (67 021 cases) with the proportion of positive rabies highest (34.92%) as well as attack rate (AR) showed the most high (0.125%). The number of rabies from 2008 to July 2015 as many as 1,157 cases of rabies and the positive opportunities of dog bite cases continue to rise even odds 83.07 times greater than the previous year. The average prevalence in Bali is showed 16.1%, the highest in Karangasem district (26.1%), but the proportion is highest seen in Bangli district (16.94%). The increasing cases of dog bites there seem to be the influence of the season. It is seen that the number of cases of wild dogs bite or semi free-range dogs likely to increase following cycles of dogs breeding season, most occur in the dry season (April to November), except in 2008 most of the rainy season (December to March) were recorded 8 cases. It was concluded that rabies is endemic, the majority occurred in the local wild dog or semi-free-ranging dogs especially in breeding season and never yet vaccinated for rabies.
