We have had a flu bug hit our school this week. 
1) People who have had symptoms of viral gastrointestinal illness such as nausea, vomiting and or diarrhea in the past 48 hours should stay at home, and avoid situations where they could easily pass the linens on to others, including public gatherings, work and school. Please let the parents know that if their kids are still experiencing symptoms, let them stay home and recover.
2) Always wash your hands well for at least 20 seconds with warm water and liquid soap. Always wash your hand before and after using the washroom, before eating or preparing foods, and after helping someone who is ill.
