Coronavirus: How does the coronavirus survive on solid surfaces for a long time? Research revealed


Scientists from all over the world are constantly researching to get more and more information about the coronavirus. Earlier research has shown that this virus can survive on solid surfaces for many hours or several days, but now how scientists can find it is possible. In a recent study, it has been said that the coronavirus sticks to thin liquid layers and survives on the surface for a long time. This research has been done by researchers of IIT Mumbai. This study report has also been published in the journal Physics of Fluids. Researchers say that this information related to the survival of the coronavirus on various surfaces may help control Kovid-19.

Researchers say that in recent experiments, it has been found that while normal particles released through the breath wither within a few seconds, the coronavirus remains in existence for a long time. He has also mentioned in research how the nanometer-liquid layer sticks to the surface due to the 'London Van der Waals Force' and due to this factor, the coronavirus is able to remain alive on a surface for hours.

Professor Rajneesh Bhardwaj, who led the study, says that the survival of the virus inside the droplet depends on how fast it dries. According to Professor Rajneesh in the Mechanical Engineering Department of IIT Bombay, when there is no medium, the virus is much less likely to survive due to the evaporation of the droplets.

Professor Amit Agarwal, who is in the team of researchers, says that our study shows that surfaces like smartphone screens and wood need to be cleaned more often than glass and steel surfaces, as compared to surfaces like glass or steel The time of evaporation of these surfaces is slow by 60 percent.

According to Professor Rajneesh Bhardwaj, higher temperatures in Delhi can slow the infection rate of corona as compared to Mumbai. He warns that there is a possibility that moisture may help the virus survive long-term droplets. He has urged authorities to enforce stringent rules for using masks in areas with high humidity.

On which surfaces does the virus stay alive for how long?

According to research by the Australian agency CSIRO, mobile phones can survive for up to 28 days at temperatures of 20 degrees Celsius and in the dark on smooth surfaces such as mobile phone glass, plastic, stainless steel, and banknotes. However, the virus cannot survive after 14 days on a cloth-like surface. So take care of cleanliness and make a habit of keeping hands and touchscreen clean. Only then can you stop the coronavirus from spreading.
