Home and Office Disinfection Guidelines

Top 3 questions usually asked about home and office disinfection

It's almost the end of 2020 and Covid-19 seems to be staying until no one knows when. We can not be too careful when it comes to preventing this disease from hitting our home and office. When we say we want to be really careful, we assume that all people that we meet, whether family, friends or officemates, might be infected without our knowledge. As such, home and office disinfection have become our second nature.

Though the difficulty of this situation seems to loom indefinitely, it is a relief that guidelines on home and office disinfection are published by trusted resources such as CDC and WHO.

1. What areas should be prioritized for home and office disinfection?

Home and Office Disinfection practices are important to reduce the potential for Covid-19 virus contamination in office, schools, gyms, publicly accessible buildings, churches, markets, transportation and business settings or restaurants.

High touch surfaces in these non-health care facilities should be identified and prioritized such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.

2. Which disinfectants are effective against Covid-19 for home and office disinfection?

For home and office disinfection, the most accessible disinfectants are:

i. Sodium hypochlorite (bleach / chlorine). This may be used at a recommended concentration of 0.1% or 1,000ppm (1 part of 5% strength household bleach to 49 parts of water).

ii. Alcohol at 70-90% can also be used for surface disinfection.

For disinfecting homes and offices, surfaces must be cleaned with water and soap or a detergent first to remove dirt, followed by disinfection. Cleaning should always start from the least soiled (cleanest) area to the most soiled (dirtiest) area in order to not spread the dirty to areas that are less soiled.

All disinfectant solutions should be stored in opaque containers, in a well-ventilated, covered area that is not exposed to direct sunlight and ideally should be freshly prepared every day.
