There have been no known human cases of influenza caused by H5N2 orH5N8 strains to date.
HOWEVER
Those with contact with poultry should have annual influenza vaccine
If a producer has influenza-like illness, they should limit contact with theirchickens to reduce the risk of co-infection with seasonal flu and avianinfluenza.

What Will Happen if My Flock is Found Positive forHighly-Pathogenic Avian Influenza?
Laboratory confirmation of HPAI.
Humane depopulation with compensation.
Appropriate disposal, which may include onsite (In Place) composting.
Cleaning and disinfection of premises. Repopulation allowed after an appropriate down time.
These measures may seem drastic and would be unfortunate for a producerto face, but are necessary to control the spread of this highly-contagiousdisease to other flocks.
