173 Neb. Admin. Code, ch. 3, § 003
Children showing any signs or symptoms of a contagious or infectious disease are required by law to be sent to their homes immediately, or as soon as safe and proper conveyance can be found.
Teachers are encouraged to observe each child carefully for signs of illness each time the child returns to school. This is particularly important when epidemic diseases are known to be present in the community.
The presence of one or more of the following signs or symptoms should make the teacher suspect a communicable disease:
Fever, flushed face, headache, aches in muscles or joints, unexplained tiredness or listlessness, loss of appetite, stomach ache, nausea or vomiting, diarrhea, convulsions, sore throat, nasal congestion or discharge, unexplained skin eruption, sore or inflamed eyes.
