A new study has revealed they another facet of the SARS-CoV-2 virus which causes COVID-19.
In the newest research, Scientists from Australia’s national science agency CSIRO found that the virus could stay of some surfaces for up to a month!
Low temperatures, non-porous surfaces
According to the study, the virus was able to survive for longer at lower temperatures (20 degrees Celsius). It also survived longer on smooth surfaces, such as glass and stainless steel. On the other end, it stayed for significantly a shorter time on porous surfaces such as cotton. It also survived for longer on paper banknotes than plastic ones.
Previous studies early in the outbreak of the pandemic found that the virus stayed on steel for up to 9 days. However, this new development will certainly change how we view the virus.
The study was published in the Virology Journal.
Director of the Australian Centre for Disease Preparedness, Trevor Drew, said that the new study was proof that we needed to continue with proper sanitary practises.
“This research shows that we need to continue to wash our hands and sanitise door handles, cutlery, cash machines and other commonly used surfaces,” Trevor said. The Australian CDP lead the research
However, Trevor said that they performed the study in a worst-case scenario. One of the caveats was that they conducted the study in a dark environment. This was so that they could negate the effects of UV rays. UV rays can kill the virus. Additionally, They also had very high viral loads. Thus, the virus could survive for a shorter period in the real world.
Furthermore, the fact that the virus survived for longer under cooler conditions, Trevor said, could explain why the risk of infection was higher in winter.
The news comes just days after scientists confirmed that the virus was indeed airborne. It travelled faster in the air when one was indoors and the place had poor ventilation.
