We get this type of bug yearly, this could be scare mongering but will take extra care.
Had a similar virus last year really bad quite ill for 2 to 3 weeks.
Best precautions wash hands regulary, and always when you have come back from shopping etc, all those hands that have touched shop doors yuk!
Also try not to get in crowd situations (hard i know this time of year) but limit yourself to local shopping if possible, large shopping complex's are rife with germs and a good place for such a bug to multiply.
Oh well with shelves not being stocked up in shops, possible energy cuts and now this plus the cold the Brits have got a lot to look forward to then lol!
I think i'll stay here under my throw and stay away from the crowds talking to you all it seems safer lol! ATISHOOOO!!!! OH NO! only kidding!
