>>9606316Perhaps you are talking about this study
https://www.journalofhospitalinfection.com/article/S0195-6701(20)30046-3/fulltextThe reason I avoid mentioning hard numbers is because those are all over the place and depend on surface material, RH/AT type of virus and strain. The results are too much of a clusterfuck to actually make a simple statement about it.
It survives 15 minutes to 2 weeks.
The only think to take note is:
Non porous: long survivavility
Porous: medium survivavility
Water absorbent: low survivavility
Copper is non porous but kills shit much much quicker than its non porous counterparts.
Tissues are best but may let the stuff through
Skin is great too until the day they discover it can infect you through your pores.
Higher RH and AT can dramatically accelerate the virus deactivation.
