Keeping your home clean and disinfected will prevent the spread of coronavirus, and any other virus for that matter.
If no one in your household is showing symptoms or has been diagnosed, then the chances of the virus living on a surface in your home are less likely. But that doesn't mean the risk is non-existent, especially if any member of the household needs to leave the house. The most important surfaces to clean regularly are the ones you touch most often. This will reduce the likelihood of the virus transferring from a surface to your hands.
