FREEHOLD — Nausea, chest pains, breathing difficulties, skin rashes — those were just a few of the complaints of the 65 people who suddenly fell ill at Monmouth County Courthouse today.

It was the second time in two business days the courthouse had to be evacuated because of a mysterious problem and, as a result, the building will be closed Tuesday, county spokesperson William Heine said.

The mass illness brought more than a dozen ambulances, sheriff's emergency vans and a county HazMat unit to the courthouse in Freehold Borough.

Twenty-five people were taken to CentraState Medical Center in Freehold township and Jersey Shore University Medical Center in Neptune between noon and 1 p.m. Another 40 were treated outside the courthouse where a triage and treatment area was set up.

"For the safety and well-being of employees and individuals with business at the courthouse, the county is cooperating with the state Judiciary to close the building," Deputy County Administrator Kevin Burke said in a statement.

In Burke’s statement, he said, "It is believed that there is no danger of person-to-person transmission. Anyone who was at the courthouse today should launder the clothes that they wore separately from other items. Individuals should also shower with soap and water as well.

"If a courthouse employee or anyone having business at the courthouse is experiencing any of the symptoms, we encourage them to go to the emergency room or their private physician.

"We also ask that they contact the county health department at 732-431-7456 to report any symptoms."
