I thought one of the doctors here would reply....
but I think that if you just leave it out of its case all the time so that it can dry completely, any germs will die off. Most need moisture to survive and multiply.
I'm a surgeon, not a microbiologist, but I would have thought the same. There are some diseases that form spores and some viruses that can withstand desiccation but I don't think flu is one of them. Although it is possible it is also fairly unlikely that you have flu - at least as in "influenza": A rather nasty common cold is more likely. I'm not saying this to be disparaging in any way, merely to point out that even then, the drying out advice almost certainly holds true.
Get well soon!
