Hmmm maybe you should call NHS direct for advice, tell them someone at work has just been diagnosed with swine flu, considerin that you do have asthma should you be taking extra precautions.
One pupil at a school near where I live has been diagnosed with swine flu, the school was closed down for a week I think and one teacher also suffering from asthma has been given Tamiflu, the rest of them havent though, you have nothing to lose by calling them really, the number is 0845 4647, it may help put your mind at ease?
Like bunty I am not nervous and take it as it comes, but then I never really worry about myself being ill, but oh my if it is someone else its totally different...
I hope all goes well for you, if you do call NHS direct please let us know what they advise.
