At least 91 passengers on a Princess Cruises ship have been hit by a suspected case of norovirus.

The virus was detected on the first day of the Sun Princess cruise to the South Pacific.

Princess Cruises said passengers had boarded the ship for a 10-day cruise when they began reporting symptoms.

Australian health authorities confirmed the cases after the ship arrived in Brisbane.

The Sun Princess was affected by two similar cases in February.

A spokesman for the cruise line said: “Proactive and successful steps were taken on board Sun Princess to limit any spread of the illness.

“The first case was reported on day one of the cruise suggesting the illness was introduced to the ship during embarkation in Brisbane.”
