Using Calmergé is simple. Teachers create an account and then invite parents to join with a unique access code. After registering, parents may share important health information with their child’s teacher such as food allergies, including severity and symptoms, or a new diagnosis of a communicable disease (e.g. head lice or influenza). With our patent pending feature, parents may share health information with the class anonymously, ensuring stigmatization or peer exclusion is minimized. Calmergé allows each parent to view a collective list of class allergies or current illnesses. The spread of contagious diseases may be lessened with real-time notification of potential exposures, allowing for early symptom monitoring.
