True, the Norwalk type Viruses are classified as "17 nm" (17 nanometers) 
viruses, which mean they pass filters with openings that size and larger.
They are also very resistant to chlorine, withstanding common pool 
concentrations. 
( one of the vectors for this bug, apparently, is the accidental ingestion of 
contaminated pool water. )
Boiling is a good way, chlorine is next best.
combining the two, is most sure.
We have industrial sized bottles of Purel hand sanitizer, Paper plates as 
plate liners, a washup sink wit running filtered water and a drain rinning to 
a sump away from the camp for cooks hands, and boiling pots of wash 
and rinse water at every meal at pennsic, and we strongly encourage their 
use and we have not had a bonified case of the Pennsic trots in five years.
Plenty of the other maladies, dehydration, mild alcohol toxicosis, sleep 
deprivation ( "the Drums! the Drums!!" ) etc.
But we seem to have this one dealt with. The fact that 40% of our campers 
happen to be chirurgeons, may help here...
