The cylindrical emergency and infectious diseases unit at Malmö University Hospital, Sweden, is designed to minimize the risk of spreading diseases. The distinctive shape also provides a new landmark for the hospital complex. Patients enter the isolation ward via an airlock from the walkway that surrounds the entire building. The exterior lifts are used exclusively by patients of the infectious diseases unit and for hospital waste, while the interior lifts are used to transport staff, supplies and clean materials. Each storey can be divided into sealed-off smaller units in the event of an epidemic.
