Salute with korea, korean government is putting forward health every citizen and guarantee health of citizen to enjoy health, one of them like your post.
Examining the stool to detect the outbreak of disease transmission. In my country have also done that, but every student is given pills to avoid children suffering from deworming. Unfortunately not in follow-up about the effectiveness of programs that have been run.
My friend
Your country also has a sanitary policy for the people.
But now in Korea stool sample collection has disappeared.
As I know, only 4.3% of the people have it, so the meaning of the test is gone.
But as you say, I think the action should have the follow-up content.
The country thinks it should be responsible to the people who make it.
