Between 15 and 20 Australians who came to ski in the
South in August and September went home with a norovirus they
may have picked up in Cardrona township.
Fifty-three people in total have been confirmed as having
suffered from the norovirus, which causes a range of symptoms
from muscle aches, headaches and coughs to diarrhoea and
Public Health South medical officer of health Dr Derek Bell,
of Queenstown, told the Otago Daily Times yesterday
the organisation had been contacted directly by the
Australians on their return home.
The Australians had travelled to Cardrona and met friends
there, some of whom were ill.
"And then while they were there they had sufficient instances
of illness amongst their groups to think that there could
have been something going on."
Dr Bell expected the total number of cases to be greater than
53 because not all cases would have been reported to Public
Contamination of the Cardrona township water supply is
believed to have been the cause of the norovirus outbreak,
which was halted by a "boil-water" policy.
