On Monday, the Centers for Disease Control and Prevention said the risk of Surface Transmission of Covid-19 is low. More important than this is the airborne transmission. The people who obsessively disinfect the surfaces may be doing more harm than good. Vincent Hill, Chief of the Waterborne Disease Prevention Branch, said, “CDC determined that the risk of Surface Transmission is low, and secondary to the primary routes of virus transmission through direct contact droplets and aerosols.”
The households with one person being Covid-19 positive did have lower transmission levels when the household had cleaned and disinfected the surfaces. CDC said that keeping surfaces clean is not a waste of time ad it is the only way to reduce the risks. Updated guidance for cleaning and disinfecting surfaces has been provided in community settings in light of the transmission risk.
Hill said, “In most situations, cleaning surfaces using soap or detergent, and not disinfecting, is enough to reduce the already low risk of virus transmission through surfaces. Disinfecting surfaces is typically not necessary unless a sick person or someone positive for COVID-19 has been in the home within the last 24 hours.”
