KEY POINTS:
A norovirus outbreak at the scout jamboree in Christchurch is still claiming victims and now a chicken pox outbreak has begun.
Canterbury medical officer of health Dr Alastair Humphrey said there were 13 people left in the tent hospital, 25 in the holding tent and two in the newly erected chicken pox tent.
At its peak 55 people were suffering from norovirus symptoms of vomiting, stomach aches and diarrhoea.
Dr Humphrey said he was disappointed the number of norovirus sufferers had not come down more.
"It's not been a good day, but the number is still going down."
"The problem now is a chicken pox outbreak among the Fijian contingent."
Fijian children are more susceptible to chicken pox than New Zealand children, Dr Humphrey said.
The Fijian scouts were being checked daily for new chicken pox cases and two children have been isolated to prevent it spreading.
Chicken pox is most contagious in the early period of the illness.
As the Fijian scouts will be travelling around New Zealand before going home the sick children will be able to carry on with the rest of their troop, Dr Humphrey said.
Some of those with norovirus are not so lucky.
They will have to remain behind when the jamboree ends on Saturday as they may still be contagious.
Dr Humphrey was not sure exactly how many people would have to remain behind.
Yesterday, Dr Humphrey told NZPA camp officials were handling the norovirus outbreak well.
"I would describe it as a textbook response to an outbreak. One of our hospital managers pointed out it's hard enough controlling norovirus in a hospital and this seems to have been contained in a tent city, which is remarkable."
