As a responsible teacher, once I saw one of my students with chickn pox, I will immediately stop the class on the grounds that one of my students has a contagious disease. But definitely, I will not alert everyone in a way that will affect the social well being of the affected student in a negative way. I will immediately call the parents of my students after I have called the attention of the school clinic. I will then advise the guardians to momentarily look after their children and make them rest until they recover if found affected by the disease. If not, make them go to school.
