From what i know of is this.
H5N1 can currently only be caught with close contact with birds, the virus though is getting weaker. This should sound like good news but it isnt. When it mutates and becomes weaker it can then be easily caught and passed from human to human.
There is NO CURE at present, they can only alleviate the symptoms.
The world seems to be stock piling medical equipmet to deal with such outbreaks.
If it happens it could kill 1 in 80 people.
My advice, buy some extra tinned food everytime you go shopping and store it in your attic. You never know......
