KEY POINTS:
Fifty staff at Queenstown's Copthorne Hotel had anti-hepatitis jabs yesterday after revelations they had worked beside an infected colleague.
A waitress was diagnosed with hepatitis A on May 4 after serving food from April 11 and exposing up to about 6900 people to the virus.
"We believe we've protected staff as best we can and we hope that we don't get any more cases," medical officer of health Dr Marion Poore said.
Poore said officials were still trying to find some of the guests who had eaten at the hotel and were particularly interested in anyone who had eaten pastries and fruit from the breakfast buffet.
Hotel manager Roger Oakes told the Herald on Sunday he had been in the job for only seven weeks when the waitress fell ill.
He said there was only a small risk to guests and staff and he believed the waitress had been discharged from hospital and returned to Korea.
Poore said most people make a full recovery from the disease, which causes liver inflammation and nausea.
Other symptoms include a loss of appetite, vomiting, jaundice, dark urine and pale faeces.
People should contact their doctor if they think they have come into contact with the waitress or have symptoms of the disease.
One Queenstown surgery said only one or two people had visited its Saturday drop-in session concerned about hepatitis A.
