We often have to exclude people from work / school / nurseries if they have had had certain types of food posioning or notifiable disease.
They can only return to their place of employment / education when they have had 2 or 3 clear results from their stool samples.
We have to go and inform them of what illness they have had as they have often gone to the doctor but not had the results and the doctor has just notified the CDC ( for which they get paid ) .
Anyways many years ago I had to go and explain to a mother that her 12 month old baby needed to be excluded from the nursery and she had to provide 3 stool samples in the little pots we gave her and which had like an ice cream spoon on the inside of the lid to help scoop the substance into the pot.
English was not her first language and when I went back the next day to collect the pot and send it off to the lab she was most distressed ...not as distressed as the baby however
She had been trying to insert the spoon up the little boys bottom and retrieve the sample from source so to speak
. She hadn't thought it would be ok to scrape it off the nappy
