NEARLY 200 Passengers On One Of World's Largest Cruise Ships Are Being Treated For GASTRO

Nearly 200 passengers on one of the world's largest cruise ships are being treated for gastro as the liner docks in Hobart.

Ovation of the Seas, which carries more than 5800 passengers, has been sailing for two weeks and arrived in Tasmania on Tuesday after a trip to Singapore.

Crew members decked out in industrial cleaning suits complete with face masks were seen spraying down hallways of the lavish ship in a video posted to Facebook.

A spokesperson from Royal Caribbean International, which owns the ship, said all guests affected by gastro were given over-the-counter medication by doctors.


'We hope all our guests feel better. Meanwhile, we're taking steps like intensive sanitary procedures to minimise the risk of any further issues.'

The spokesperson said the ship would be 'comprehensively sanitised and cleansed' once it arrived at its next port in Sydney, resulting in a slight delay for new guests.

The Tasmanian Health Service said the outbreak of gastro on cruise ships was 'not unusual'.

'It is not unusual for gastroenteritis outbreaks to occur aboard cruise ships, just as it is within the normal population,' a spokesman told the ABC.

'Cruise ships have their own medical teams, medical surveillance systems, outbreak control measures and are well-trained in treating passengers.'
