The United States Center for Disease Control and Prevention (CDC) updated its guidelines for cleaning and disinfecting sites to prevent the spread of Covid-19, the entity’s director general, Rochelle Walensky, said on Monday (5) during a meeting of the White House Covid-19 Response Team.

Science has recently shown that people can be infected through contaminated surfaces, but the risk of this happening is low. Cleaning the places with detergent or soap regularly is enough. Disinfection is not necessary, said Walensky.

“Disinfection is only recommended in closed places, schools or homes where there are suspected or confirmed cases of Covid-19, within the past 24 hours,” he explained.

In most cases, nebulisations, fumigations and electrostatic sprays are not recommended as primary methods of disinfection, and in reality bring several health risks.

Transmission through surfaces can also be reduced by the correct and consistent use of masks, said Walensky, along with hand hygiene.
