173 Neb. Admin. Code, ch. 3, § 005
Children excluded for a confirmed communicable disease should not be allowed to return to school until the minimum isolation period has elapsed, and all signs or symptoms of acute illness have disappeared. The period of exclusion should extend throughout the period when acute signs of illness are present, or until the student is fever-free for 24 hours without the use of fever-reducing medication.
Minimum isolation periods are shown in the table on Attachment 1, Contagious and Infectious Disease/Condition Chart, which is attached to 173 NAC 3 and incorporated by this reference. School boards and boards of education may observe these periods, or adopt and enforce their own exclusion regulations which may not be shorter or less restrictive than those contained in 173 NAC 3.
