Prepared to Be Ill?

Are you prepared for illness?  A week and half ago we went to the city and neglected some precautions.  Before we go out into large masses of people we always slip an Elderberry and Zinc lozenge into out mouth.  This helps kill any germs we may breath in.  Well, we had to go to the VA hospital and FORGOT to use the lozenge!!!!  Of course, I caught some nasty bug that is still with me.  Hopefully I will be feeling much better by next week and can post better advice on preparing for illness.
