Dozens of healthcare workers across the US are testing positive for coronavirus as they battle the highly-infectious disease on the front lines.
At a Chicago suburban hospital, two emergency room physicians have been diagnosed with the virus.
Meanwhile, in nearby St Louis, Missouri, two doctors associated with Washington University tested positive for COVID-19, the disease caused by coronavirus.
And 200 people Children's Hospital have been tested for coronavirus after a doctor was confirmed to have the virus.
It comes as the Centers for Disease Control and Prevention loosens their guidelines and says healthcare workers can work even if they've been exposed to coronavirus as long as they wear a mask.
