According to the US Centers for Disease Control and Prevention, the risk of surface transmission of COVID-19 appears to be low. Airborne transmission is way more significant and those who constantly disinfect surfaces may be doing more harm than good.

The US CDC noted that the risk of surface transmission was low, and was secondary to the primary routes of transmission through direct contact droplets and aerosols, said Vincent Hill, Chief of the Waterborne Disease Prevention Branch.
