Respiratory & hygiene
Given that transmission of influenza predominantly occurs through inhalation of respiratory droplets produced when people cough or sneeze, preventive respiratory etiquette should be reinforced. Respiratory etiquette involves covering coughs/sneezes with a tissue/cloth or coughing/sneezing into one’s sleeve to prevent the dispersion of respiratory droplets into the air. When someone coughs or sneezes, respiratory droplets that contain viruses may also land on their hands, clothes, surfaces (tables, door knobs/handles, plates, cups, etc.). Thus touching someone’s hands or clothes, or surfaces, and then touching the mouth or nose or eye without washing hands first, or using utensils without washing them, may also transmit the virus. Thus hand washing/hygiene may also help prevent transmission. In addition, the use of personal protection equipment listed below, can lessen the risk of exposure.
