Two more Adelaide schools have shut down after a student and teacher tested positive to coronavirus.

Henley High School will close until Friday, effectively shutting the schools doors for the rest of the term due to next week’s pupil free days.

The school’s closure comes less than 24 hours after Pennington School R-7, in Pennington, was also shut due to a COVID-19 case.

A staff member was diagnosed with the deadly virus on Wednesday.

The schools’ closures come after the education union revealed more than 70 per cent of teachers believed students were not following social distancing rules.

Airport and pharmacy cases

An employee at a popular pharmacy chain in the city’s western suburbs has also tested positive to coronavirus.

“National Pharmacies confirms that on Tuesday 31 March an employee at our Findon store tested positive for COVID-19,” the chemist chain said in a statement.

“National Pharmacies is working closely with SA Health to identify anyone who many have had contact with the employee.”

The pharmacy says the staff member had contracted the virus through a connection to the Adelaide Airport cluster.

“The employee is recovering in isolation at her home,” it said.

“A further 15 employees who worked with her are in isolation at the direction of SA Health and are being tested for COVID-19 as appropriate.”

SA Health says contact must be face-to-face for 15 minutes for a person to contract coronavirus so it is unlikely customers are at risk, but says anyone who begins to feel unwell should contact their GP.
