Although a single sneeze releases up to 40,000 droplets,[96] most of these droplets are quite large and will quickly settle out of the air.[94] How long influenza survives in airborne droplets seems to be influenced by the levels of humidity and UV radiation, with low humidity and a lack of sunlight in winter aiding its survival;[94] ideal conditions can allow it to live for an hour in the atmosphere.[97]
