In most cases, the influenza virus is transmitted by droplets, through the coughing and sneezing of infected persons, but it can also be transmitted by airborne droplet nuclei as well as by contact, either through direct skin-to-skin contact or through indirect contact with contaminated en -

      Influenza is thought to spread by droplet, contact and airborne routes. However, the relative likelihood of spread due to each of these modes is not well understood. Respiratory droplets are currently thought to be the main mode of transmission (Bridges, 2003). There is also some

      This virus did not transmit via the airborne route, suggesting that markers in NS1 and NEP are important, but not sufficient, for mammalian airborne transmissibility (Fig. 1 F and G). To determine if any mutations were present in viruses that trans-mitted by direct contact (DC) or by airborne contact (AC), we se-
