Tips to Reduce the Spread of Cold Viruses in the Classroom

In addition to routine hand washing and respiratory etiquette, below are some tips on cleaning classrooms to reduce the spread of cold viruses. Note: Please be sure to consult with your administration and/or school board about cleaning product policies.

Influenza (the flu) viruses can live on surfaces for up to 48 hours. Therefore, daily cleaning and disinfection of the classroom is recommended especially during cold and flu seasons. Cleaning and disinfection should focus on surfaces and objects that are touched often, such as desks, computer keyboards, doorknobs, faucet handles, phones and toys.

General household cleaners are sufficient to remove germs. Afterwards, you can use a disinfectant that has a drug identification number (DIN) or natural product number (NPN) and indicates it is effective against influenza A. The DIN and NPN means the disinfectant has been approved by Health Canada. Read the disinfectant label for directions on appropriate use, dilution, mixing, contact times (i.e., how long a surface must remain wet in order for the disinfectant to work), as well as how often the disinfectant should be replaced. Be sure to also check the expiration date on all disinfectant products.
