According to WHO, there is no confirmed timeline how long a COVID-19 virus survives in surfaces. However, most likely it behaves like other coronaviruses. Studies show that coronaviruses can survive on surfaces for a few hours up to several days depending on varied conditions (e.g. type of surface, temperature or humidity of the environment).
If you suspect that a surface is infected, clean it with disinfectant; clean your hands with alcohol-based hand sanitizer or wash them with soap and water; and if possible, minimize touching your eyes, mouth or nose. 
The coronavirus can live for hours to days on surfaces like countertops and doorknobs. How long it survives depends on the material the surface is made from. 
Here’s how long the virus typically lasts on common surfaces: 
- Glass – 5 days
- Wood – 4 days
- Plastic & stainless-steel – 3 days
- Cardboard – 24 hours
- Copper surfaces – 4 hours
