The Monroe County School Health Coordinator provided us with a helpful resource to protect yourself and your family. We’ve also posted it on our School Nurse’s page: http://maysandsmontessori.com/resources/school-nurse/
The best way to prevent illness is proper hand hygiene. Hand washing should be done with soap and water for at least 20 seconds. Avoid touching your face or mouth to prevent germs from your hands entering your system.
It is also important to stay home from work or school if you develop symptoms to prevent the spread of illness to others. Face masks are not 100% effective at protecting you from these viruses and are not currently recommended by the CDC for the general population.
