The New Jersey Department of Health has its first probable case of monkeypox virus in Jersey City.

Health officials say the person is now isolating at home, while the state undergoes contact tracing.

Officials say the risk of infection in New Jersey is still low.

Monkeypox does not spread easily from person to person without close, prolonged contact.

Monkeypox causes a rash that usually begins on the face, and spreads to the rest of the body, creating itchy scabs.  

People usually experience flu-like symptoms.

That outbreak began in May. The illness has since been found in 20 states and Washington, D.C.

Gov. Phil Murphy says the state is keeping a close eye on this outbreak.

"It’s something we’re taking seriously. But I’d say to folks: Stay calm. And if you have any question — and you’re not feeling well, you’ve got that fever, you’ve got a rash, lumps, whatever it might be — go to your health care provider. That's the best advice," said Murphy.

Monkeypox is rarely deadly, and, usually, people do not need treatment.

Most people get better on their own, but it can take up to three weeks.
