At WBEZ (and maybe at your office too?) it seems like a lot of folks get sick at almost exactly the same time.
But why?! Simple: People in our office are sick because sick people are in our office.“I think that is probably the single biggest thing that we could do to reduce the incidence of a lot of diseases,” says Sarah Cobey, an evolutionary microbiologist from the University of Chicago. "Just self-quarantine." 
On this episode of Nerdette, Sarah takes a walk through our open office and guesses why people might be ill — and what we can do to stop the colds from spreading. She also talks about sneezes, vaccines and all the real heroes out there: people with good hygiene. 
Wash your hands, people! Sheesh!
