By contrast, Influenza A virus has been discovered to survive on surfaces for 17 days.
” It actually reinforces the value of washing hands and sanitising where possible and definitely wiping down surface areas that may be in contact with the virus,” said the studys lead scientist Shane Riddell.
The research study included drying virus in an artificial mucous on a series of surfaces at concentrations similar to samples from COVID-19 patients and then recuperating the infection over a month.
Experiments done at 20, 30 and 40 degrees C revealed the virus survived longer at cooler temperatures, longer on smooth surface areas than on complex surface areas such as cotton, and longer on paper banknotes than on plastic banknotes.
” So heading into summer season thats certainly going to be a crucial aspect that the infection will not last as long in the warmer temperature levels,” Riddell stated, referring to the upcoming southern hemisphere summer.
All the experiments were performed in the dark to remove the impact of ultraviolet light, as research study has actually revealed direct sunlight can kill the virus.
” So in the real life results would likely be much shorter than what we were able to show,” Riddell told Reuters.
Researchers said considered that proteins and fats in body fluids can also sharply increase virus survival times, their research study may assist discuss the evident perseverance and spread of the infection in cool environments like meat-packing centers.
Australia has actually fared far better than many other abundant countries in combating COVID-19, with a total of about 27,000 infections and 898 deaths in a population of 25 million.
The epicentre of the countrys second wave of infection, Victoria state, reported 15 new cases on Monday, well shy of a target of less than five which the government has set for the easing of a difficult lockdown in the state capital Melbourne.
New South Wales, the most populous state, reported six brand-new cases on Monday, 5 of whom were returned tourists in quarantine.

MELBOURNE/SYDNEY (Reuters) – The virus that causes COVID-19 can survive on banknotes, glass and stainless-steel for as much as 28 days, a lot longer than the influenza virus, Australian scientists stated on Monday, highlighting the need for cleansing and handwashing to combat the infection.
Findings from the study done by Australias nationwide science company, CSIRO, appear to reveal that in a very regulated environment the infection remained transmittable for longer than other research studies have actually found.
CSIRO researchers discovered that at 20 degrees Celsius (68 degrees Fahrenheit) the SARS-COV-2 infection stayed contagious for 28 days on smooth surface areas such as plastic banknotes and glass found on mobile phone screens. The research study was released in Virology Journal.
