Illness in the classroom affects students and staff every year.
Eighty-three percent of 35 surveyed Manor Heights students and their families experienced vomiting over a four day period last December.
Over 50 Manor Heights students were affected by norovirus on a single day in December 2016.
Natrona County School nurses told News 13, through education and awareness they do their best to keep children safe.
NCSD Nurse, Wendy Wilson commented, “School nurses in the Natrona County School District try to do the absolute best to keep children healthy. We do a lot of education with both the students and with families as to how to prevent them from getting sick."
Fourteen illnesses listed in an, online 'illness protocol' display what is too sick to attend school.
If your child has chicken pox, norovirus, scabies or strep throat NCSD staff wants you to keep them out of school.
"Vomiting or diarrhea, please keep them home and if they have a vomiting or diarrhea illness it’s more than likely a virus and please make sure you keep them home for 24 hours."
Natrona County Health Department staff said washing your hands and drying with paper towels is one of the best methods to prevent spreading illnesses and norovirus.
"In the fall and winter the numbers will peak and its highly contagious.”
Ruth Heald at the Natrona County Health Department said, “It's stomach symptoms, nausea, vomiting, diarrhea and cramping that type of thing usually last anywhere from 24 to 48 hours."
Wilson added they started seeing norovirus reports around Thanksgiving last year and they hope this year’s numbers are not in season.
When it comes to things like rashes without a fever, mild respiratory or cold symptoms they say your child can attend school.
