Thousands of people aboard the Costa Smeralda cruise ship are being given the OK to disembark after Italian authorities confirmed that a sick passenger tested negative for the coronavirus.

The ship, which was carrying around 5,023 passengers and 1,628 crew members, was being held in a port at Civitavecchia, Italy, after a passenger from Macau, China, began exhibiting flu-like symptoms on Wednesday. Smeralda passengers had been prohibited from disembarking until the results of the woman’s tests came back.
