Dutch researchers report first death from COVID-19 reinfection

Dutch researchers report first death from COVID-19 reinfection”

The virus responsible for Covid-19 can survive for up to four weeks on surfaces including banknotes and mobile phone screens, researchers have claimed.

Scientists from the national science agency CSRIO found the SARS-CoV-2 - the virus which causes COVID-19 - was more likely to survive in lower temperatures and on non-porous or smooth surfaces such as glass, stainless steel, and vinyl.

In the first study, researchers from the University of Toronto (Toronto, ON, Canada) and the Lunenfeld-Tanenbaum Research Institute at Sinai Health (Toronto, ON, Canada) found that coronavirus antibodies can last at least three months after a person becomes infected with the virus. Since UV light has been shown to kill the virus, the experiment was conducted in the dark.

Experts say 68-degrees Fahrenheit is the flawless temperature for the virus to thrive on smooth surfaces, like glass, steel and plastic.

Previous tests had shown that the SARS-Cov-2 virus could survive for only two to three days on glass and banknotes.

"It seems that it lasts longer than other viruses such as influenza, which only lasts a few days, or even other coronaviruses", she said.

The research could also increase calls to sanitise door handles, cash machines and other commonly used surfaces.

The team stressed that the COVID-19 virus can stay active on glass-like surfaces for a long time.

According to the research paper, survival rates of SARS-CoV-2 were determined at different temperatures.

"What we wanted to do is really to highlight just how the potential for this virus to be transmitted by contact rather than just through direct exposure to someone who is infected", he said.

USA researchers have confirmed the country's first case of COVID-19 reinfection, indicating that exposure to the virus may not translate to total immunity. It lived the longest - almost a month - at 68-degrees Fahrenheit, which of course is room temperature in many homes and offices. More porous surfaces, such as cotton, were not found to enable the virus to thrive for as long.

Researchers in Australia explored how long the virus survived under controlled temperatures and humidity settings on common surfaces.

"So in the actual world outcomes would seemingly be shorter than what we had been capable of present", Shane Riddell, the lead researcher within the research printed Monday within the Virology Journal, advised the information company.

There's lots we don't know about coronavirus, but the longer the pandemic goes on, the more scientists are learning about it.

Coronavirus has turned out to be a deadly virus as many people are losing their lives. Drew. He further added that the study can help understand the apparent persistence and transmission of the virus in cooler environments with high levels of protein or lipid contamination.
