Turns out, when nursing home staff work at multiple facilities, infections like COVID-19 spread way faster—especially in crowded homes. Researchers found that keeping staff-sharing below 5% really helps stop outbreaks, but once it goes over 30%, even masks and vaccines can’t keep up. Basically, more shared staff = more risk for everyone. If you’ve got loved ones in nursing homes, this is something to watch! #NursingHomes #COVID19 #Healthcare #Health
