Emergency crews responded around 1:00 p.m. to the hospital, located at 100 Townsend Avenue.
The Camden County Prosecutor's Office says a woman in Winslow opened an envelope and experienced a burning sensation on her hands.
The woman allegedly transported herself to Virtua for treatment. Upon her arrival she was isolated, a hazmat team was called to the scene, and the hospital was quarantined.
Hazmat crews investigated, and after determining that there was no substance or white powder in the envelope, a test was conducted on the envelope itself. The results of that test concluded that the envelope was non-toxic.
Authorities say the woman involved has a history of skin sensitivity to glue and glue from the envelope is thought to be what caused her symptoms.
The hospital was then cleared and has returned to normal operation.
The hospital says all precautions have been taken and no other patients or employees are affected.
