The outbreak of campylobacter that put a Havelock North retirement village in lockdown yesterday is being investigated by the Hawke's Bay District Health Board.
Patients with gastro at Mary Doyle Lifecare retirement village have been restricted from visitors and "infection control measures" have been put in place.
Yesterday the Hawke's Bay District Health Board said five people at the village had been affected by the outbreak, but today that number had gone down to three.
A Hawke's Bay District Health Board spokesperson said "at this stage" of the investigation they did not believe the outbreak was related to the water-borne campylobacter outbreak that affected more than 4,700 people in Havelock North.
"Gastro outbreaks are not uncommon in aged residential care facilities," the spokesperson said.
Mary Doyle Lifecare is the same retirement village where 89-year-old Jean Sparksman died on Saturday after contracting campylobacter.
