  • There have been no reported cases of H5N8 in humans.
  • The risk to the general public is quite low.

  • During control and containment efforts, however, adequate care must be taken when handling sick/dead birds and contaminated material.
  • Eating properly prepared poultry items is deemed safe.


  • Control measures include:


  • When an infection is found in animals, culling is frequently done to control it.
  • Aside from culling, proper disposal of all culled animals and animal products is critical.
