What are the preventive measures to control norovirus outbreaks?

Question

Hi doctor,

I am working in a retirement home, and we had 12 cases of norovirus last month. Now it is back again and has affected a few residents and staff. What cleaning products are effective in killing norovirus? How long should sick staff stay home? What solid prevention strategies can we implement to control this outbreak?

Please help me.

Thanks.

Hi,

Welcome to icliniq.com.

I can understand your concern.

Disinfecting areas contaminated with norovirus is crucial due to the virus's highly contagious nature. It can be done by following the steps.

Always use disposable gloves to protect yourself from exposure.
Clean the area: Before disinfecting, clean the surface with soap and water to remove visible dirt and debris.
Check for disinfectant products labeled as effective against norovirus or other viruses with similar resistance, such as Clostridium difficile or rotavirus.
You can use a diluted bleach solution (1/3 cup of bleach in 1 gallon of water). Ensure the solution is fresh and the area is well-ventilated when applying.
Apply the disinfectant generously to the contaminated surface. Ensure the disinfectant sits on the surface for the required time (usually five to ten minutes) to effectively kill the virus.
After allowing the disinfectant to sit for the recommended time, wipe down the surface with clean paper towels or disposable cloths.
Wash any contaminated fabrics in hot water with a good detergent. Add bleach if it is safe for the fabric.
After cleaning, dispose of all disposable materials in a sealed trash bag to prevent further contamination.
Wash your hands thoroughly with soap and water for at least 20 seconds after cleaning.
Always ensure that cleaning and disinfecting procedures are thorough and repeated as necessary, especially in high-traffic or frequently touched areas.

I hope this information helps you.
