Baltimore firefighters have evacuated two medical research buildings due to possible tuberculosis contamination.
A Johns Hopkins Medicine spokeswoman says the fire department is investigating ‘the possible release of a small amount of tuberculosis’ in an internal bridge between two cancer research buildings.
Officials did not say how it might have been released.
According to local news station WBALTV, teams arrived in hazmat gear. A statement from Hopkins says the buildings were evacuated Thursday as a ‘cautionary measure.’
