"So far, all indications are that no other individuals have been exposed, however, the buildings will remain evacuated until cleared by public safety officials", the statement read.
There were employees in the area when the incident occurred, but hospital officials told the Baltimore Sun that no one required treatment.
Two buildings on the campus of a reputable Baltimore hospital were evacuated because of the fear of people being exposed to tuberculosis, as per a new report.
Kim Hoppe, a spokeswoman with Johns Hopkins Medicine, said a small sample of frozen tuberculosis was "inadvertently released" in an internal bridge between two cancer research buildings that don't connect to the hospital.
Because the buildings were used for research, no patients were in either building, according to the report.
The amount released was equivalent to only a few drops, and no one was hurt, according to King. Authorities said employees on the site do not need to do additional tests as authorities declared no incidence of health risks.
Baltimore fire officials were not immediately available for comment. TB primarily affects the lungs and can become airborne.
He added that the people who were on or near the site of exposure do not need additional testing.
Tuberculosis is a highly contagious bacteria that can be spread through the air.
The Baltimore Fire Department said they received a call shortly after noon to say that a tuberculosis sample had been spilled. It can be fatal if it goes untreated. According to the Center for Disease Control and Prevention, symptoms of tuberculosis include coughing, chest pain, fatigue, fever and loss of appetite. The same year, around 10.6 million people were infected with the disease across the globe with the disease and around 1.7 million died due to it.
