whyAvian Influenza virus is so…. dangerous?

mild illness


  • Mutates rapidly, (=can be adapted to other

    animal species;)

  • Can cause severe disease in humans;

  • The disease in poultry may be “mild” with ruffled

    feathers and reduced egg production, thus going

    undetected by the owner.

  • Surviving birds excrete virus for at least 10 days

The Severe form of the disease is (highly contagious and fatal)

Slide4 l.jpg

  • It is transmitted easily from poultry to poultry or from poultry to humans

  • through:

  • a) mechanical ways,

  • - contaminated equipment,

  • - vehicles,

  • - feed,

  • - cages,

  • - clothing

  • b) inhalation of desiccated infected poultry faeces……..

  • Can survive for long in the environment,

  • especially when temperatures are low.

  • Therefore Refrigeration of infected meat

  • and eggs doesn’t protect anyone from the virus!!
