How Much Bleach With Water For Ebola Virus Disinfection

How Much Bleach With Water For Ebola Virus Disinfection

Add 1 part bleach to 9 parts water (1:10 dilution factor)

From the Public Health Agency of Canada:

EBOLA VIRUS SUSCEPTIBILITY TO DISINFECTANTS:
Ebolavirus is susceptible to 3% acetic acid, 1% glutaraldehyde, alcohol-based products,

and dilutions (1:10 – 1:100 for ≥10 minutes) of 5.25% household bleach (sodium hypochlorite), and calcium hypochlorite (bleach powder).

The WHO recommendations for cleaning up spills of blood or body fluids suggest flooding the area with a 1:10 dilutions of 5.25% household bleach for 10 minutes for surfaces that can tolerate stronger bleach solutions (e.g., cement, metal).

For surfaces that may corrode or discolor, they recommend careful cleaning to remove visible stains followed by contact with a 1:100 dilution of 5.25% household bleach for more than 10 minutes.

Note: While the Ebola virus disinfection advice given above references 5.25% bleach, today’s newer regular bleach is typically 8.25% concentration (of sodium hypochlorite) and therefore a bit stronger (implying a slightly less required bleach-to-water ratio). However, given the use-case scenario (Ebola virus) I would still follow the same recommendation of 1 part regular bleach to 10 parts water (a slightly stronger solution will only help matters while using 8.25% regular bleach).

Example: To make a bit more than half a gallon of Ebola virus disinfectant, simply use a 1-cup measuring cup and dump 1 cup of regular bleach into a bucket, and then add 9 cups of water.

If anyone finds more specific information from the CDC or WHO, regarding bleach-to-water ratio for disinfecting Ebola virus, let us know…

For those of you in health care, hospital workers, etc., what are you being told regarding Ebola virus disinfection (if anything)?
