- The new coronavirus is primarily a respiratory illness, and it typically spreads via airborne droplets from an infected person’s coughs or sneezes.
- Viral particles can survive for a time on surfaces, but the coronavirus’ lifespan on surfaces depends on various factors like temperature and humidity.
- New research suggests the coronavirus can last between three hours and three days on surfaces, depending on the material.
- Here are some best practices for disinfecting surfaces.

The new coronavirus is a respiratory illness, which means it typically spreads via airborne droplets. When an infected person coughs or sneezes, droplets carrying viral particles can land on someone else’s nose or mouth or get inhaled.
But a person can also get the coronavirus if they touch a surface or object that has viral particles on it and then touch their mouth, nose, or eyes. The lifespan of the virus on a surface — a subway pole, a stairwell banister, or even money — depends on many factors, including the surrounding temperature, humidity, and type of surface.
But the rough range is “likely hours to a day or so,” Rachel Graham, an epidemiologist at the University of North Carolina, told Business Insider.
New research published Wednesday from the National Institutes of Health (NIH) supports Graham’s assessment. The study suggests the virus can live up to four hours on copper, up to a day on cardboard, and up to three days on plastic and stainless steel. The coronavirus can also live in the air for up to three hours, the study authors found.
Their research has yet to be peer reviewed, however.
