Affected population On Thursday 20 August, a six-month-old dog was taken to the veterinarian since he was showing a decreased appetite without neurological signs and again the next day (Friday, 21 August) following a deterioration of his general condition with convulsions, aggressiveness, visual loss and difficulties to move. He was hospitalized and died on the night from Friday to Saturday. A rabies investigation was then launched and the Pasteur Institute confirmed the diagnosis on 31 August 2015.

Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments The virus isolated in the dog is a Lyssavirus of RABV species and of “vampire bat rabies” type. It is estimated that the virus excretion phase started on 5 August. During this period, the dog was in a fully fenced house. No run away was reported during the period. He just went out for some walks on a lead in the neighborhood and some visits to the veterinarian. The dog did not bite but could have chewed or lick wounds or the face. The epidemiological investigation has identified to date 12 contact people and no contact animals. However, there are stray cats near the house where the rabid dog was. Although the origin of the contamination of the dog is still uncertain, the most likely hypothesis is the contact with a bat, since the dog has eaten several times dead animals found in the garden. Following confirmation of the diagnosis, a regulated zone was put in place in order to limit the movements of domestic carnivores, to establish increased surveillance and to strengthen the capture of stray animals. Carnivores non properly vaccinated that could have had contact with the case will be euthanized. Carnivores properly vaccinated that could have had contact with the case will be under clinical monitoring for 6 months.
