In light of the situation, the U.S. Centers for Disease Control and Prevention will further test the seafarer for COVID-19 as he previously didn’t undergo the testing.

Approximately 255 people onboard the vessel were found COVID-19 positive since 1st of March, marking one of the largest outbreaks on a cruise ship.

For the records, the cruise ship "Disney Wonder" had docked in San Diego on March 19 to offload its last passengers after the industry's lockdown.

As a result, several passengers and crewmembers who tested positive for COVID-19, were hospitalized, while others were isolated in their cabins.

As Miami Herald reported, the ship has a “provisionally green” status from the CDC, meaning there have not been any crew members showing COVID-19-like illnesses for 28 days. Specifically, the last coronavirus positive case onboard was marked on May 8, according to the company.
