Epidemiology
Source of the outbreak(s) or origin of infection
  • Unknown or inconclusive
Epidemiological comments Ducks are mostly raised in these localities near Lake Albert. Mortality has been higher in ducks than in hens. Positive samples have been taken on 21 ducks and one hen. Quantitative information provided concerns the ducks. H5N8 avian influenza virus is present in the neighbouring country Uganda. Dense trade exchanges, mainly of poultry and poultry products, between the Democratic Republic of Congo and Uganda should not be overlooked. Duck mortality is high in Joo and Kafe. Surveillance has been reinforced in the containment zone to prevent the spread of the disease to the other Ituri territories. Other investigations are planned shortly in other territories of the province.
