Hi,

I was wondering if someone could help me understand the spread of germs better.

I know that norovirus isn't airborne, but small particles of it can be left in the air. Does this not mean that if we are near a person who has this, (or another vomiting bug), or near vomit, that we can easily breathe this in and get infected too? I take it there's no way of preventing this type of spreading of germs?

Are food poisoning bacteria such as E Coli, salmonella and staphylococcus also able to spread in the air? Can normal antibacterial solutions such as Dettol spray kill all of potential food poisoning germs on surfaces?
