Coronaviruses (including preliminary information on the (COVID-19) virus) may persist on surfaces for a few hours or up to several days (5 hours to 9 days). This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).
If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
