A Havelock North woman, in her forties, was admitted to Hawke's Bay Fallen Soldiers' Memorial Hospital on Friday, with symptoms that have been confirmed as Guillain-Barrē Syndrome.

The patient is in a stable condition and is progressing well with the treatment she has received.

Hawke's Bay Hospital Physician Andrew Burns said the patient had diarrhoeal symptoms during the Havelock North campylobacter outbreak in August.

Dr Burns said Havelock North residents who experience 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.
