Unwell Students (Cough, runny nose, fever,vomiting etc.) If your child is unwell please keep them at home. If your child has vomitted the night before, please keep them at home, even if you think they are okay. The NSW Health guidelines suggest that students who have vomitted should be kept at home for 48 hours to help prevent the spread of illness through the school. Please see the guideline from NSW Health regarding vomiting. https://www.health.nsw.gov.au/Infectious/factsheets/Factsheets/viral-gastroenteritis.pdf
