COVID-19 pandemic: CDC issues interim cleaning, disinfection recommendations after exposure
Washington — In light of emerging data on the COVID-19 pandemic, the Centers for Disease Control and Prevention has released interim environmental cleaning and disinfection recommendations for community facilities with suspected or confirmed cases of the potentially deadly respiratory illness.
The guidelines – aimed at limiting the spread of the disease – are focused on community, non-health care facilities such as schools, institutions of higher education, offices, day care facilities, businesses, and community centers that “do, and do not, house persons overnight.”
SARS-CoV-2 – the coronavirus that causes COVID-19 – can be stable for several hours to even days on various surfaces, results of a study that involved CDC researchers and was published online March 17 in the New England Journal of Medicine show.
“Cleaning of visibly dirty surfaces, followed by disinfection, is the best practice measure for prevention of COVID-19 and other viral respiratory illnesses in community settings,” CDC states on its Cleaning and Disinfection for Community Facilities webpage, which the agency intends to update as more data is made available.
Cleaning should entail using a detergent or soap and water before disinfecting. Diluted household bleach solutions, solutions with at least 70% alcohol or other Environmental Protection Agency-registered household disinfectants are recommended.
CDC also provides information on how to clean soft or porous surfaces. In addition, personal protective equipment, such as disposable gloves and gowns, should be worn by cleaning staff, who are encouraged to wash their hands frequently.
Employers should provide education on COVID-19 to workers performing duties such as cleaning, laundry and garbage pickup.
“These guidelines are not meant for cleaning staff in health care facilities or repatriation sites, households, or for others for whom specific guidance already exists,” CDC states.
