Remember a virus needs to survive till it can get into a living being and replicate. Consider what to date is known about possible lurking virus in our surroundings.Data can show for example in wood as late as 5 days some protein from virus can be measured, however a viable virus lasts much less, it must come off totally intact to infect a human.This blog address the duration for a ‘viable’ virus on surfaces. Much is common sense for instance NEVER shake used or unused clothing, sheets or clothing. The virus becomes ‘glued’ on a porous surface, it is very inert and disintegrates in 3 hours and also on fabric, it takes 4 hours on wood, because it removes all moisture and does not let it detach and so it disintegrates. Virus does not survive cooper as it is antiseptic! On cardboard it hangs in for 24 hours, 42 hours on metal and 72 hours on plastic surfaces. But if you shake it or use a duster, the virus molecules float in the air for up to 3 hours and can settle in your nose, eyes or mouth – you will not sense it.
Viral molecules remain very stable in external or artificial cold like air conditioners in homes and cars. They also need moisture to remain stable and especially darkness. Therefore, dehumidified, dry, warm and bright environments will degrade it more quickly.
* UV LIGHT especially UV-C breaks the virus protein – inactivates.
