A ward has been closed and visitors urged to stay away from Hawke's Bay Hospital following a stomach bug outbreak.
More than a dozen staff and patients in the Assessment Treatment and Rehabilitation (AT&R) Ward at the Hastings hospital have fallen ill with vomiting and diarrhoea symptoms in the last two days.
Chief operating officer Warrick Frater said samples had been sent away to investigate the cause of the illness, and a warning issued to visitors to keep away.
"It was important visitors stayed away from the hospital if they had vomiting or diarrhoea as the virus could spread rapidly and become a problem for patients who were already unwell," he said.
The AT&R Ward was completely closed to visitors as "stringent hygiene measures" were put in place throughout the hospital to contain the outbreak.
