The US Navy has announced that a sailor on board the Wasp-class amphibious assault ship USS Boxer (LHD 4) has tested presumptive positive for coronavirus (Covid-19).

The individual is undergoing quarantine at home in line with guidelines issued by the Center for Disease Control (CDC).

The test result has been sent to the CDC for confirmation and is considered presumptive positive.

The people who have been in close contact with the infected sailor are currently in self-isolation at their homes and are not reported to be on the ship.

In a statement, the US Navy said: “US Navy ships conduct routine, daily cleanliness procedures geared toward health, wellness and the prevention of communicable disease spread.

Additional precautionary measures are expected to be undertaken based on the investigation results.
