Hawke's Bay health authorities are investigating if there is a link between a man with Guillain-Barre syndrome in Wellington Hospital and the campylobacter outbreak that rocked Havelock North last month.
A Hawke's Bay Hospital spokeswoman said today that the Hawke's Bay public health team was following it up at this stage to see if there was any relation to the gastro outbreak which left 5000 Havelock North residents sick.
The Hawke's Bay District Health Board was advised by the Capital and Coast District Health Board today.
The man, who is in his 60s, is currently in a stable condition in the intensive care unit.
Two women were admitted to Hawke's Bay Hospital with Guillain-Barre syndrome earlier this month.
Havelock North resident Kerry Mackintosh was one of the woman and was now suffering from reactive arthritis.
April Singh was also diagnosed with the syndrome and is still recovering from the illness at her home in Havelock North.
Hawke's Bay Hospital physician Andrew Burns had said previously Ms Singh had diarrhoea symptoms during the Havelock North campylobacter outbreak in August.
The Hawke's Bay District Health Board could confirm it has no one in Hawke's Bay Hospital with GBS at the moment.
Mr Burns said any residents who experienced pins and needles, weakness or clumsiness of hands or feet should seek medical help quickly.
"Early treatment of this condition can impact on the severity, so early diagnosis is important," he said.
