The Gauteng health department is investigating the cause of a fire that broke out early Monday morning at a hospital in Pretoria, South Africa's capital.
The fire that damaged temporary structures at Steve Biko Hospital caused no injuries to patients or workers, according to a statement released by the South African government.
The fire was eventually extinguished.
As a precaution, the authorities stated that 18 patients and one body had to be relocated to other parts of the hospital.
The fire's cause was unknown, and an inquiry was underway.
Since last year, there have been three fires at hospitals.
In April of last year, around 700 patients were evacuated from Charlotte Maxeke Facility in Johannesburg due to a fire, which forced the hospital to close for a week.
