| Bird Flu |  |  | Birds are being blamed for the spread of some global flu 
strains | 
 What if avian flu or bird flu arrived sooner than 
expected in the North West?
  Scientists say millions of people could 
be killed by a flu pandemic, but the advice from health officials in the North 
West is, "Don't go to hospital or the doctors".  With the prospect 
of little or no vaccine, medical centres could be overwhelmed by patients they 
cannot help. 
 Pandemics of influenza have swept the world from time 
to timethroughout history, three times in the last century.
 Scientists 
fear a global epidemic of deadly flu in humans will strike, and bird flu is giving 
cause for particular concern There are 15 different strains of the virus, 
but it is the H5N1 strain which is infecting humans and causing high death rates. This 
type of flu is highly contagious and has also killed dozens of people since re-emerging 
in South East Asia in 2003.  Spread by birds, there is not yet a definitive 
vaccine, but prototypes which offer protection against the H5N1 strain are being 
produced.  However anti-viral drugs, which are already available, may help 
limit symptoms and reduce the chances the disease will spread.  |  |  | Flu attack? Could the virus spread to humans in the UK? | 
  These flu viruses occur naturally among birds. Wild birds world-wide 
carry the viruses in their intestines, but usually do not get sick from them. 
 Professor Hugh Pennington of Aberdeen University recently told 成人快手 News 
Online that, "The virus is carried in the chicken's gut.  "A person 
would have to dry out the chicken meat and would have to sniff the carcass to 
be at any risk. But even then, it would be very hard to become infected." 
 Experts say that the UK is at "very low risk" of developing the 
disease at present.  Although bird flu viruses do not usually infect humans, 
several cases of human infection have occurred since 1997. Symptoms in humans 
include typical flu-like symptoms such as fever, sore throat, muscle aches, severe 
respiratory diseases and coughs. It is thought that the majority 
of human bird flu infections resulted from contact with infected poultry or contaminated 
surfaces. Inside Out's Andy Johnson asks how would we cope if bird 
flu came to the North West of England, and asks if we are we prepared for a flu 
epidemic. Links relating to this story: The
