Not sure how much of this is a true increase, but there may be a particularly nasty virus going around that usually just causes the common cold, known as Adenovirus 14. There’s a JAMA report out from the CDC about it just yesterday; it seems to be causing pretty severe illness in even the young and healthy, putting an 18 year-old in the ICU in Oregon.
Please, wash your hands–no matter if you’re sick or well–before eating, after using the bathroom, before touching your face, all that. And if you’re sick, well, I’m sorry. And that’s what sick days are for. Rest up and get well soon.
