Virus that causes Covid-19 can survive on surfaces for 28 days

The study goes on to explain that the virus was isolated for up to 28 days at 20°C from common surfaces such as glass, stainless steel and both paper and polymer banknotes. And these information could be used to indicate the higher risk of increasing infection rate and prevent the rapid spread of corona virus. comparing with coronavirus, influenza A can survive in normal room temperature at the smooth surfaces for 17 days.

Previous research has proven that the virus might be infectious in airborne particles for over three hours but did not confirm the extent to which it can spread through surfaces like banknotes and touchscreens.

It's worth noting though that some natural conditions may work in our favor, such as sunlight - UV light is thought to kill the virus on surfaces. The patient survived his second bout with COVID-19.

They said another plausible explanation could be the mechanism of antibody dependent enhancement in which some protective proteins produced by the immune system during the first encounter with the virus could make a subsequent infection worse.

Experts say, however, that people are more likely to contract the coronavirus from someone else rather than from a surface.

The study published in The Lancet Infectious Diseases journal also reported the first confirmed case of COVID-19 reinfection in the United States. Using genome sequencing, the scientists have shown that two different strains of the virus are involved. To determine the answer, scientists at the University of Arizona conducted a study and found that the immunity against COVID-19 may last for several months.

One of the key questions in predicting the course of the COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is how well and how long the immune responses protect the host from reinfection.

"She was discharged after 5 days and besides some persisting fatigue her symptoms subsided completely", said a study, via "Clinical Infectious Diseases". They found that they could detect it after 28 days on all these surfaces at 20C - significantly longer than the earlier studies had indicated. "All individuals, whether previously diagnosed with COVID-19 or not, should take identical precautions to avoid infection with SARS-CoV-2".

"It really reinforces the importance of washing hands and sanitising where possible and certainly wiping down surfaces that may be in contact with the virus."

Dr. Ashish Jha, dean of the Brown University School of Public Health, said Tuesday there have been other cases of COVID-19 reinfection.
