Nurse tests positive to COVID-19 in Adelaide as state cancels iconic show

An intensive care nurse at the Royal Adelaide Hospital working with COVID-19 patients has tested positive for the virus.

The nurse, in her 20s, is in isolation at home while she recovers.

SA Health says she became mildly symptomatic late on April 10, was tested on April 12, with the positive test result returned yesterday.

So far, 23 close contacts have been advised to self-isolate, including 22 RAH staff, predominantly nurses and two doctors.

But investigations by the Communicable Disease Control Branch are ongoing.

SA Health said the situation was not expected to impact patient care at the RAH with sufficient staffing available.

So far South Australia has 431 confirmed coronavirus cases with 14 people in hospital and six in intensive care at the RAH.

Low numbers have been recorded in recent days, including just two yesterday and none on Sunday.

However, concerns over the virus remain strong enough that the Royal Adelaide Show has been put "in hibernation" for this year, with a view to holding the next one in 2021.

The show was to be held in September, showing the length of the coronavirus timetable the state is working to.

It's just the fifth time the show has been cancelled in 181 years.
