An Oamaru retirement village remains closed to visitors after a mystery bug swept through the facility last week. Observatory Village Lifecare, in Stoke St, was put into lockdown last Wednesday after the first cases of the yet-to-be-determined virus were reported the previous day. Symptoms among the unconfirmed number of residents and staff who had been affected included vomiting and diarrhoea. Specimens had been sent away for testing but Observatory Village Lifecare general manager Rosie Dwyer said the nature of the bug was yet to be determined. It was hoped the facility would open to the public by the weekend at the latest.
