whyAvian Influenza virus is so…. dangerous? mild illness BECAUSE • 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)
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!! 21
