An Indianapolis hospital is preparing to reopen its emergency room after an unknown substance sickened seven people.
Riley Hospital for Children President Dr, Jeff Sperring said Thursday night the hospital has received clearance from external authorities to re-open the emergency room. He says it expects to resume normal operations there later in the evening.
The emergency room closed around noon Thursday after an unknown substance caused seven people to become ill. Some were taken to other hospitals while others were released after treatment.
The nature of the substance and its source haven't been identified. Sperring says officials have inspected the property including parking garages.
