The New Jersey State Health Department says monkeypox was a contributing factor in the death of a North Jersey man last month – the first death in the state linked to the disease.

Officials say that the person who died had underlying medical conditions. The patient was confirmed to have had monkeypox in mid-September.

Details about the patient and when he died were not released.

Health officials say that cases of monkeypox have been declining in New Jersey over the past few weeks.

“However, it is important to note that the disease is still circulating, and in some cases, may cause severe illness or death,” officials wrote in a statement.

Health officials say that those at a higher risk include people with weakened immune systems, children under the age of 8, those who are pregnant or nursing and “individuals with certain conditions that affect skin integrity.”

New Jersey has confirmed 751 probable and confirmed case of monkeypox as of Nov. 2. Symptoms include a rash, fever, headache, swollen lymph nodes and muscle and backache.

Free vaccines are available at participating health sites. More information can be found on the state’s health website.
