TRENTON, N.J. (AP) — New Jersey health officials have linked two more fungal meningitis cases to a nationwide outbreak caused by a potentially tainted medication.

The two cases bring the total in the state to four. All four patients are residents of Cumberland County. Three are being treated at South Jersey Healthcare Regional Medical Center in Vineland and a fourth is being treated as an outpatient.

The two new cases are a 59-year-old man who received a steroid injection a month ago, and a 52-year-old woman who received an injection in August.

Health officials say more than 600 patients in New Jersey received the steroid injection at six facilities between May 21 and September 26.

Nationwide, the drug sold by a Massachusetts-based pharmacy has been linked to 14 deaths and about 170 illnesses.
