Coronavirus Can Survive on Surfaces for Days by Transforming into a Microscopic Pancake-like Film

News 18  

According to a new study, the virus responsible for Covid-19 can remain infectious on most of the surfaces for several days as it transforms itself into a microscopic pancake-like film after the water content in the particle has evaporated. The researchers have also noted that the conversion sees more than 99.9 percent of the droplet’s liquid content vanish within a span of a few minutes, however, the virus still thrives in a protective film of the remaining fluid. Professors at the Indian Institute of Technology Bombay – Rajneesh Bharadwaj and Amit Agarwal used computer modelling and advanced physics applications to understand how the virus droplets can spread the disease. “It is desirable to disinfect frequently touched surfaces, such as door handles or hand-held devices, and within hospitals and other areas prone to outbreaks,” said Prof Agrawal.
