How to Prevent Norovirus Spreading

by Matt Besley on 08-12-2017


Norovirus or the "Winter vomiting Bug" is doing the rounds again. This common diarrhoea and sickness causing virus is very infectious.

How can you prevent this from spreading, and how should you clean after an outbreak? 

How is Norovirus spread?

Norovirus spreads very easily in public places such as hospitals, nursing homes and schools.

You can catch it through:

  • Close contact with someone with norovirus – they may breathe out small particles containing the virus that you could inhale
  • Touching contaminated surfaces or objects – the virus can survive outside the body for several days
  • Eating contaminated food – this can happen if an infected person doesn't wash their hands before handling food

A person with norovirus is most infectious from when their symptoms start until 48 hours after all their symptoms have passed, although they may also be infectious for a short time before and after this.

How can you stop it spreading?

  • Get everyone to wash their hands regularly and thoroughly with soap & water and dry them properly.
  • Ensure infected persons stay away from school or work, for at least 48 hours.
  • Sanitise all surfaces.

How should you clean?  

Sanitise all touch points and surfaces with a bleach based product or a Special Sanitiser tested to EN 14476 against Norovirus, like Easy Dose HP Cleaner or the Catering Uniwipes.

Another good measure for a school or office affected, is to "Fog" a sanitiser into rooms to sanitise all the exposed surfaces in the room. Eliminator is an interesting product; an Aerosol Sanitising Fogger, that needs no special equipment.

Using Windmill Easy Dose HP Cleaner to Sanitise


  1. Make up a solution of HP Cleaner at a concentrated dilution (3.5 doses)
  2. Spray all contact surfaces including door handles and push plates.
  3. Leave for a 5 minute contact time
  4. Wipe off with a cloth.

The chemical concentration and contact time is really important here as this is the chemical strength and contact time that has been used in a laboritory and proved to be effective.

Using Windmill Eliminator to Sanitise


Using an aerosol fogger is an excellent way of holistically sanitising a space, and is safe on all surfaces.  

  1. Clean all the touch points, e.g. door handles and push plates etc. with a sanitiser or a wipe as described above
  2. Close the room off 
  3. Place the can in the middle of the room.  One can will do up to 40 square meters - use more than one can for larger spaces.
  4. Push down the cap on the top of the can and exit the room
  5. Leave for 1 hour minimum
  6. Remove the can and air the room

Uniwipes are such a good idea when you have norovirus as you can use the wipes and throw them out when you finish which makes it really hygienic.  The Catering Uniwipes meet the requirements of EN1276, EN1650 and EN13697 and will kill Norovirus, MRSA and H1N1.

Make sure you have the test results of the product you are going to use as a sanitiser and that your cleaning staff know what dilution and contact time they need to use, see below downloads.
