As such, you are advised to clean your working surfaces like your table or kitchen regularly using soap and water or disinfectant with around 70% alcohol content or 0.5% hydrogen peroxide.  In addition, you should wash your hands regular with soap and water for 20 seconds (or use alcohol based hand rub when you do not have access to soap and water).  Try to AVOID TOUCHING your face, nose, mouth or eyes because this is how the virus can infect you.
