The Indian embassy here on Tuesday said it was in touch with 138 Indians, including passengers and crew members, on board a cruise ship carrying 3,711 people which was quarantined off Japan because of the diagnosis of some coronavirus cases.

The Diamond Princess arrived at the Japanese coast early last week and was quarantined after a passenger who had got down last month in Hong Kong was found to be the carrier of the virus on the ship.

Around 60 people tested positive of the virus on Monday, taking the total number of those infected on the ship to 130. Authorities had initially tested 300 people when the ship arrived at the Japanese coast.

“The situation is being monitored closely,” an Indian embassy official said after being asked if there are any arrangements made by the mission to offload the Indians from the ship.

“There are a total of 138 Indian nationals on the ship. The Indian Embassy is in touch with them,” the official said, adding that the Indians on the ship have not been tested for coronavirus.

Those on the ship have been asked to wear masks and allowed limited access to the open decks as they are advised to remain in the cabins most of the times to contain the spread of the virus, according to media reports.

Meanwhile, the operator of the ship on Monday vowed to refund all 2,666 passengers. Carnival Japan Inc said refunds will be offered via travel agencies.
