According to today’s Adelaide report, a few days ago, the detection of novel coronavirus in the CBD wastewater in Adelaide, Australia, and several consecutive days of high levels, which has caused many people to worry about whether the local South Australia community spread has occurred.
On March 12, the first medical officer, Nicola Spurrier, announced that there was no trace of Coronavirus left in the wastewater of CBD.
Health authorities have been on high alert since March 7, when they first announced a sharp increase in virus detection levels in wastewater.
Testing of the wastewater on the night of March 10, Camberra time, showed that the levels of the virus in the water were falling, but the numbers were still high, leading officials to worry about the possibility of community spread in the state.
Professor Nicola Spurrier said in an interview on the morning of 12 March Canberra time that continued monitoring of the waste water since the evening of 11 March Canberra time had seen good results.
“The really good news I got last night is that as of yesterday, the amount of Novel Coronavirus in the wastewater from Bd is zero,” Spurrier said on the morning of 12 March Canberra time.
We saw it go up before, and now we see it plummet down.”
She said the high levels detected in recent days are due to an increase in interstate visitors living in the CBD, and the virus remains from old cases are still being discharged in the wastewater.
“Of course, we will continue to monitor it, but as you can see, our CBD is getting a lot of visitors this time of year.”
The waste water collection area also includes the inner east between Hackney and Toorak Gardens, but does not include Tom’s Court Hotel, where positive patients are quarantined.
Professor Spurrier said the test result was zero on the night of 11 March Canberra time, but there was no room for complacency.
“Trying to keep a social distance from other people, I’ve been to some events and I’ve been impressed by how people have behaved,” she said.
“I knew people would come up to me and want to shake my hand.
If I refuse your hand, please do not feel bad. It is not the time to shake hands yet.”
Prime Minister Steven Marshallsaid on March 11 that the increase in visitor numbers was due to Fringe and the Adelaide Film Festival, which may have contributed to the detection of COVID-19 in Adelaide wastewater.
Tests carried out on the evening of 10 March, Canberra time, showed that levels of the virus in the water were falling, but the results were still high.
Areas with high levels of the virus included the site of the Adelaide Fringe Festival and several large hotels, including those where overseas visitors were quarantined.
“We are taking samples regularly to monitor trends, and the two most likely explanations are that visitors to the CBD have a concentration of old cases, or undetected cases in the community,” SA Health wrote in a statement.
Premier Steven Marshall said on March 11 that health authorities believe an increase in visitors to Victoria caused the novel coronavirus to turn up in Ade’s wastewater.
“The advice I was given last night is that it is highly likely that people who have come here from Victoria have been infected,” he said.
“They’ve passed the infectious period, but there are still little pieces of the disease that are showing up in our wastewater.”
Marshall said authorities would continue to monitor the situation closely.
