Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments The affected backyard has been depopulated and cleaning and disinfection are on-going. Following the epidemiological investigation, two in-contact premises were identified, but no evidence of the disease was found; however, as a precautionary measure, they will be depopulated. The zone around the outbreak has been expanded in order to further detect other cases. It is important to emphasize that this is not a rabbit breeding zone at national level and the population is very limited.
