This virus can be seen coming out of the surface of human cells cultured in laboratories and taken from patients in America by the US National Institutes of Health.
Scientists scan this virus with an electron microscope Specifically, the scan clearly shows spikes on the outer edges of virus particles that give the name corona virus – because 'corona' means crown or halos in Latin.
The scientists also discovered from the scan that the virus that caused Covid-19 was stable for several hours to days on aerosols and surfaces.
They found that the virus can be detected in aerosols for up to three hours, up to four hours in copper, up to 24 hours in cardboard and up to two to three days in plastic and stainless steel.
Director of the Centers for Disease Control and Prevention (Centers for Disease Control and Prevention (CDC)), Robert Redfield said COVID-19 will survive on copper or steel for about 2 hours. But according to him it will last longer if it is on another surface, such as paper or plastic for 9 days.
Robert Redfield suspected that being infected through direct contact with the surface of the object might be the cause of the transmission of a number of passengers and crew of the 'Diamond Princess', but not because of airborne transmission.
Not only Robert, scientists believe that such a virus can usually last around 4 to 5 days on the surface of plastic, glass, wood, paper or aluminum after leaving its host body, like the human body, but in some cases, the virus lasts longer, and these items or materials are very often touched by people in everyday life.
