Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Rabbit haemorrhagic disease (serotype RHDV2) has occurred for the first time in Senegal. Flemish giant rabbits, checkered giant rabbits and fauve de Bourgogne rabbits were affected. Clinical signs reported in the farms were fever, anorexia, conjunctivitis, epistaxis, groaning and sudden death. Investigations are on-going to identify the origin of the disease through molecular biology. In addition, in this context of coronavirus pandemia, the purchase of primers outside the country has delayed the laboratory diagnosis.
