H5N1 in Virginia

• On Friday, July 7th, a flock of turkeys tested
  positive for antibodies to H5 on routine
  pre-slaughter surveillance
• The virus was assumed to be low-path
• On July11th, the National Veterinary Services
  Laboratory typed the virus as an H5NI
• Similar to strains that had been seen in
  migratory birds in Maine and Canada

AI Rapid Response Training

• Purpose
• Identify potential for human health problems
  associated with cases of highly pathogenic avian
  influenza
• Minimize the risk of spread or further human
  infection if human infection or disease is
  identified
• Provide guidance to individuals who are involved
  in the response to HPAI cases and other HPAI
  exposure settings

15
AI Rapid Response Training

• Protect against the risk of infection and disease
  and minimize the risk of viral reassortment
• Provide guidance for multi-disciplinary rapid
  response teams to discuss, plan, and to
  facilitate discussion between state and local
  avian influenza rapid response teams
