I am a bit astounded that doctors in minor clinics in Nova Scotia can claim to have diagnosed swine flu in four high-school students. Are they using some form of test like the HIV western blot, or are they just looking at these people weezing and in light of the present hysteria, saying OH MY GOD! SWINE FLU!

How could I learn the symptoms of swine flu ?How DO the doctors diagnose the swine flu from usual one?
