Creating awareness among students , preventive interventions such as frequent hand wash , respiratory etiquettes ( using handkerchief over mouth while coughing / sneezing , use of tissue paper or using the sleeve of shirt covering upper arm , staying away from school when sick , avoiding public gatherings etc . ) would help in preventing / reducing transmission of not only this diseases , but also large number of other communicable disease , notably flu - like illnesses . Further , such informed youth can be agents of changes for their family , community and beyond ' 2 . I am therefore directed to request you to issue necessary instructions to all the schools under your control and to create awareness amongst the students .
