Coronavirus Survives on Surfaces for Days, But What Does That Really Mean?

 A major study published last week in The New England Journal of Medicine reported the novel coronavirus responsible for COVID-19 can survive on some surfaces for several days, and is even detectable in aerosols for several hours. This important research offers valuable insights into the lifespan of this new virus outside of a human body, however, some experts are suggesting the study does not mean the virus actually remains infectious on surfaces for days or can be transmitted easily through the air.

Scientists Discover Evidence of Early Human Innovation
