Well, i know if you go Poly Nursing, they do explain as part of
the curriculum involves you in contact with ill patients. They do
not want you to spread anything more to them.
As for other faculties, they only brief explanation they gave was
that because classroom is a contained environment, so they don't
want contagious diseases.
But my question is, if someone has a [email protected] lump. I don't see how
that's contagious!!!!
