I don't they can and they aren't generally bothering to even say its swine flu now.
My fil has been very ill with flu and managed to have the added complication of developing pneumonia but his sick note said flu and GP didn't mention swine flu. I don't think they are worrying about swine flue anymore.
It seems that in general swine flu replaced other flu varieties in the southern hemi-sphere. It is likely that will happen here as it has happened in previous pandemics. In general I don't suppose it matters which variety of flu you have, some people get them as relatively benign illnesses and some get severe cases.
So what do you do about the fact that some people have been swabbed and are positive for H1N1 but still only had 'bad cold' type symptoms, while other people in their family had what you'd expect for the illness 'flu' - laid up in bed for days, etc.? Same virus, different illnesses... after all we know it can also cause subclinical symptoms where people have even less than a bad cold.
It seems like you could have symptoms that are just bad cold symptoms, caused by a flu virus. Just to complicate things . (Personally I still wouldn't say I had 'flu' unless I had the laid up in bed kind of illness.)
At the end of the day a lot more people will have fluey illnesses this winter, because of all the H1N1 about. But most of us will never find out if a specific bout of illness was caused by H1N1, or something different, and it probably doesn't matter that much.
There is a testing centre in the town nearwhere I am. Something daft like 90% of people swabbed for SF (and these people were treated for SF and given Tamiflu) came back with negative results.
At one point they were diagnosing anyone with any flu symptoms as SF. TBH anyone with vague cold symptoms would have been diagnosed via the flowchart online. And the majority of people were not swabbed so have no idea if it was or wasn't SF.
Without the swb test you have no idea what it is.
It desn't really matter TBH if it is normal flu or swine flu. And a really bad cold can be as bad too. They all need treating in the same way - rest, fluids and keeping out of work/school til feeling better.
Island of Sodor - my DH was prescribed tamiflu and had no side effects and really helped within 4 hours to get temperature down (paracetamol plus nurofen maximum amounts did not bring temp down) . However, was over the weekend concerned that dd had swine flu(according to NHS website was swine flu and we got the number to pick up a prescription - only am not in UK at the moment so that would not have been possible anyway). Took her therefore to out of hours GP (yes, he wanted her to come in and sit a few chairs away from other people) and turned out that she had tonsillitis. So she is now on anti-biotics and already feeling a lot better. According to the out of hours GP if you have swollen glands it is unlikely to be swine flu (no idea why this is).
Anyway, given high level of misdiagnosis your DH might want to see GP and if this is really not possible and have high temp then get tamiflu???
Was chatting to a friend this morning whose doctor's husband is a virologist at a university working on various flu strains..apparently swine flu in its current mutation is much less debilitating than normal flu, so if you feel like a bag of shite it's prob swine flu, 2 bags and it's normal flu. <not his technical comparison tools, incidentally>
