So your worried about germs!
 

One simple question? How many people have touched your mail before you pick it up at the mail station? The packages dropped off at your front door? The door handles at the stores and the handle on the gas pump nozzle. The products you buy at the grocery store etc. Germs are EVERYWHERE period. Just try your best to be safe, wash your hands as often as you can, avoid super large crowds and hope you've done enough.
