The Centers for Disease Control and Prevention says the danger of airborne transmission is much greater.
The Centers for Disease Control and Prevention announced on Monday that the risk of surface transmission of Covid-19 is low. According to CNN, broadcasting is far more dangerous.
“The risk of surface transmission is very low, and direct contact with droplets and aerosols has become a secondary route to the main route of transmission of the virus,” said Vincent Hill, head of the water-borne disease prevention department.
Hill commented that although the room is small, there is a high risk of spreading from contact surfaces. Hill said on a conference call hosted by the Centers for Disease Control and Prevention (CDC): “Outdoors, sunlight and other factors can destroy the virus.”
The virus dies “rapidly” on porous surfaces, but can last longer on hard surfaces indoors.
Research also shows that people are most likely to spread through surfaces within the first 24 hours after being infected, and that when people clean and disinfect surfaces, the transmission rate is lower for families with Covid-19.
Due to the risk of transmission, the CDC has updated its guidelines for cleaning and disinfecting surfaces in public places.
Hill added: “In most cases, cleaning the surface with soap or detergent without disinfecting it is sufficient to reduce the risk of the virus spreading through the surface.”
“Normally, unless someone who is sick or who has tested positive for Covid-19 has been at home within the past 24 hours, there is no need to disinfect the surface.”
Hill pointed out that cleaning should be concentrated in the most accessible areas, such as door handles and light switches.
