How exactly is COVID-19 spreading? Dr. Arnot states that the most common transmission of coronavirus is person to person (within 6 feet) and from surfaces, although that appears to be less common and with no documented cases. The video goes into detail about what surfaces the virus can live on and how long it stays active before dying out. The doctor also explains why this virus is spreading so quickly and how it can invade the host more easily than previous viruses.
Went from 10 to the 3.7 initially and dropped to a 10 to the 0.6 after 48 hours
From 10 to the 3.7 initially and 10 to the 0.6 after 72 hours
Copper and Cardboard
Proved safer with no viable virus after four hours for copper and 24 hours for cardboard.
This chart shows how long the virus remains at what concentrations over time. In air, the virus gradually decreases over three hours. Looking at surfaces you can see the decay is faster for copper followed by cardboard, stainless steel, and plastic.
