After becoming VERY anxious over the flu virus attacking me and my family, I have had to get a grip, it was literally taking over my life. I have done EXTENSIVE studies on the flu topic and have come to this conclusion.
EVERYONE is different, some people are getting confirmed swine flu and having mild symptoms and some are very poorley indeed. You just have to be sensible, if you are suffering and are worried - contact your GP. If you can get the vaccine - have it, it can only help to lessen the symptoms - at least you have done everything you can. Keep clean, and use hand gel regularly and if you can, whilst this is at a peak, try not to go to public places if you can help it. There is nothing more that you can do.
