Health officials said more than 40 cases of mumps can be connected to a Jersey Shore bar.
The Star-Ledger reports that there are now 41 reported cases of mumps under investigation in the state.
Lab tests confirmed one of the suspected cases as mumps. The rest are under investigation.
Most of the suspected cases, including the one confirmed case, are connected to D'Jais Bar & Grill in Belmar.
The popular Jersey shore establishment voluntarily closed last weekend and more than 30 employees have been given the mumps vaccine.
The Health Department re-inspected D'Jais on Friday and gave the establishment a satisfactory rating.
Health officials say the number of Monmouth County residents with mumps-like symptoms is now 25. Another 16 cases are being investigated by the state Department of Health.
