As COVID-19 spreads, public health officials are telling people to stay home if they feel sick. But in jails and prisons, that's not an option.
Robert Greifinger is a physician who spent 25 years working on health care issues inside the nation's prisons and jails, and he says the "social distancing" advice we're all hearing right now isn't so simple behind bars.
"There are crowding issues, ventilation issues, security issues where people have to be checked and monitored fairly frequently," Greifinger says. "So it's really hard to do."
