Hackensaket Hospital in North Jersey is currently being treated for Ebola.
The hospital has already had one of its own confirmed patients tested for the virus, which is spreading rapidly in the U.S. and overseas.
The New Jersey Department of Health has said the patient is an Ebola patient.
The state health department says the patient had been at the hospital for a few days and was “consistent” with the hospital’s protocol.
In New Jersey, there are at least 883 confirmed Ebola cases, and the number is expected to continue to grow.
The state has not seen a new Ebola case since February.
The infection rate in the state has been rising rapidly, with many hospital workers showing up unannounced at their appointments, making it difficult for people to stay home.
The outbreak has affected about 1,300 people, including more than a dozen nurses.
A total of 1,631 people have died from the disease.
