If we are so unfortunate that we have an biological attack then you will want to quarantine yourself and family. Don't think it can't happen; and don't be embarrassed that everyone will think you are crazy. Nope! You are protecting your family. Read the following short article on quarantining. If you are wise and choose to be prepared you will also print up a sign to post in your window that states "This House Is Under Self-Quarantine". Add a skull and crossbones to make it look even more menacing.
