Coronavirus can remain infectious on surfaces for DAYS by transforming into a microscopic pancake-like film, study finds:

More than 99.9% of liquid in coronavirus droplets evaporates within minutes

But virus survives because the dried droplet turns into a pancake-like film

This sticks to a surface for hours and can remain infectious if touched
Scientists recommend cleaning surfaces regularly to ensure there is no Covid reside.

It can survive for more than 150 hours on polypropylene. A smaller droplet, just one-tenth of the size, lasts for more than 80 hours on glass.

Here's the Albert Einstein explanation for anyone interested.
