So you’re sick – and you’ve been using the same tissue to blow your nose all morning. Is that a problem? Well, according to Dr. Wendy Bennett, an internist from Johns Hopkins, that ratty tissue won’t hurt you – but it could hurt those around you. Because each time you touch it, you’re touching your infected mucus germs – and then whatever you touch afterward will be contaminated with your virus. So grab a new tissue and use that. Or sneeze into your sleeve, since that’s less likely to touch other surfaces or people.
