The governor of Delaware says that he is “mad as hell” that the state was re-added to New Jersey’s coronavirus travel advisory list.

More than half the country is now part of the advisory, including Alaska, Indiana, Maryland - and once again, Delaware. The travel advisory applies to any person coming from a state with a positive test rate higher than 10 per 100,000 residents or a state with a 10% or higher positivity rate over a seven-day rolling average.

Travelers from those states are being asked to quarantine for 14 days when they arrive in New Jersey.

Gov. John Carney reacted to the news during his COVID-19 briefing.

“Yeah, I’m mad as hell, frankly. And it doesn’t make any sense,” Carney said. “We’re better today than we were when we were first put on the list two weeks ago and we’re better today than where we were last week when we were taken off the list.”

But Gov. Phil Murphy said that Delaware was added to the list because of data, not feelings.

“He’s not happy and the problem with this is like everything else; not everyone is happy when you make the call based on data and science and it is what it is,” Murphy said.

Delaware and New Jersey share a border. The Delaware River and Bay Authority is handing out flyers to people before they board the Cape May Lewes Ferry heading to New Jersey. The authority is also making an announcement on board about the quarantine.

But some travelers tell News 12 New Jersey that the advisory will not change their plans.

“My group here, we’re going on bicycles, so we’re planning on riding around and staying clear enough away from everyone else,” said Ted Noble, of Ocean View. “I feel I’m doing my part. I don’t know that I'll quarantine to the full effect.”

Cape May County residents say that they are worried about the long-term effects the advisory will have.

“I think it will hurt the tourist trade a lot,” says Bob Brown, of Green Greek.

The ferry is running at 20% capacity. Passengers are required to wear a mask on board and are being asked to socially distance themselves from others aboard the ferry.
