The virus has also been detected in the sewage of aircraft returning to Australia from coronavirus contact points. The presence of SARS-CoV-2 was detected in 24 out of 37 aircraft by experts from the Australian National Scientific Institute (CSIRO).
For passengers to travel from abroad to Australia, they must submit a negative Covid test no later than 72 hours before departure.
CSIRO results prove it
The coronavirus can be detected in effluents before carriers develop symptoms.
The study’s lead author, Areesh Ahmed, said sewage testing would be an evaluable way to screen incoming passengers.
This provides an additional amount of data if samples taken from the nose and throat are late in detecting the infection and the passengers have not yet developed symptoms, Ahmed said.
“Rapid on-site inspections of wastewater on arrival can be effective in detecting and monitoring other infectious reagents,
which can spread all over the world. That way they can alert in the future before more outbreaks occur.”
According to CSIRO, infected individuals can clear the virus up to two days before symptoms appear. However, the virus can also be found in the stool of people who have previously had the disease but are no longer infected.
Australian authorities reported 2,185 new infections and 12 more deaths Monday morning.
The bribe, which was given two months ago due to the coronavirus, was lifted on Friday in the Australian capital, Canberra. In Sydney, the country’s most populous city, a mandatory two-week hotel quarantine for foreigners will be lifted from November 1.
In the Administrative District (ACT), which also includes the capital, a stay-at-home order was introduced in August, initially for only seven days, after the city’s first case of coronavirus was recorded since July last year. Since then the bribery lock has been extended several times.
