Quick Answer
DISINFECTANTS ARE NOT EFFECTIVE AGAINST ALL VIRUSES. MANY ENVELOPED VIRUSES, SUCH AS CORONAVIRUSES AND INFLUENZAS, REQUIRE SPECIALIZED DISINFECTANTS AND TECHNIQUES TO DESTROY. THEY ALSO DO NOT WORK AGAINST VIRUSES INSIDE HOST CELLS.
Types of Viruses
Some viruses, like HIV and herpes, are enveloped viruses that have a lipid membrane. Disinfectants that work on enveloped viruses include ethanol (at least 70%), isopropanol, and quaternary ammonium compounds. However, to be effective, the surface must be saturated with the disinfectant for at least 1 minute to 30 minutes, depending on the product and type of virus.
Disinfectant Effectiveness
In the case of non-enveloped viruses, such as norovirus and rotavirus, disinfectants like hydrogen peroxide and sodium hypochlorite are effective. However, these viruses can survive on surfaces for extended periods and require specialized cleaning and disinfection procedures. When choosing a disinfectant, look for products that are EPA-registered and specifically claim to be effective against the type of virus you are trying to eliminate.
Surface Preparation
To maximize the effectiveness of disinfectants, ensure surfaces are free of debris, dust, and other contaminants. Clean surfaces with soap and water before applying disinfectants. Use gloves and follow the product’s instructions for application and contact times to avoid exposure and ensure the virus is eliminated.
