Yes: Influenza is a respiratory illness, so it is spread when you come in contact with the droplets from a cough or a sneeze. The droplets can enter your body when you inhale them or if you touch something contaminated with droplets, and then touch your own mouth, eyes or nose. That's why keeping your hands away from your face and washing your hands frequently is so important.

...: The flu virus is spread mainly when someone with flu coughs, sneezes or talks and sends droplets out into the surrounding environment. These “droplets” can enter in the mouths or noses of nearby people. A person can also get the flu by touching something that has flu virus on it and then introducing the virus into their own mouth or nose. The flu vaccine and washing hands often prevent the spread.
