The Centers for Disease Control and Prevention is reporting a second probable case of monkeypox in New Jersey.

But it’s not known where the person with the new case is located.

It comes as the CDC has opened an emergency center in response to the outbreak, which will be used to deal with the outbreak response from the government, as well as nongovernment agencies' response.

The facility was already supporting the CDC’s reaction to the pandemic. It’s also where experts monitor other public health emergencies, such as hurricanes, earthquakes and oil spills.

Health officials are also expanding the group of people recommended to get vaccinated against the virus.
