Stool classification

Cryptosporidiosis characterised by Acute diarrhoea – watery liquid diarrhoea

But someone recovering from Cryptosporidiosis can continue to carry oocysts in their stools for up to 14 days

Solid faeces in pools

• Scoop the poop and put it where it should be

• Unlikely to be from someone with an acute gastric

illness

• If the operator is not certain of 100% removal

then treat as runny faeces

• Dependent upon the contamination we

recommend closing for say 30mins to allow all

visual evidence to be removed or dissipate

Runny faeces in pools

• If it’s a diarrhoeal type of incident then

suspect crypto

• Most viruses and bacteria killed in seconds

by chlorine not so crypto

• Safest option is to close the pool

• Multi solution – filtraton/coagulation,

superchlorination, UV

UV recommended by PWTAG

Staff competence

Welsh study showed

• Many pools did not have and could not draw

a schematic drawing of the pipework layout

• They did not have appropriate management

of their filter operation

• Had limited or no policy for dealing with a

crypto incident
