etiology

ETIOLOGY

Classification of the causative agent

Virus family Orthomyxoviridae, genus Influenzavirus A, B. To date, all highly pathogenic isolates have been influenza A viruses of subtypes H5 and H7

slide4
HOST
  • Highly pathogenic avian influenza isolates have been obtained primarily from chickens and turkeys 
  • It is reasonable to assume all avian species are susceptible to infection
transmission
TRANSMISSION
  • Direct contact with secretions from infected birds, excretion especially feces 
  • Contaminated feed, water, equipment and clothing 
  • Clinically normal waterfowl and sea birds may introduce the virus into flocks 
  • Broken contaminated eggs may infect chicks in the incubator   
sources of virus
SOURCES OF VIRUS
  • Feces, respiratory secretions 
  • Highly pathogenic viruses may remain viable for long period of time in infected feces, tissues and water

Some also develop life-threatening complications such as viral pneumonia and acute respiratory distress syndrome

But the greatest complication of bird flu is still hypothetical

solutions
SOLUTIONS
  • No specific treatment
  • But now, the primary treatment option remains the flu drug oseltamivir (Tamiflu), that works by preventing the virus from escaping its host cell
sanitary prophylaxis
Sanitary prophylaxis
  • Avoidance of contact between poultry and wild birds, particularly waterfowl 
  • Avoidance of the introduction of birds of unkown health status into a flock 
  • Control of human traffic 
  • Proper cleaning and disinfection procedures 
  • Practice an “all in-all out” system in the poultry farm
in outbreaks
