just got back from Russia AND the UK...go ahead and go..just take the usual precautions that you would nornally take..wash your hands before eating, avoid those people who are coughing and sneezing a lot, get lots of rest...and eat a healthy balanced diet.

If it will make you feel better, go to one of the pharmacies and ask if they have something that will boost your immune system before you go...I know there is one that you inhale...

If you pick up a starving dog and make him prosperous, he will not bite you; that is the main difference between a dog and man.
