Person to Person
The main way that influenza viruses are thought to spread is from person to person in respiratory droplets of coughs and sneezes. (This is called "droplet spread.")

If you have a dry, hacking cough, dextromethorphan may give you relief. Generally, these cough syrups and cough medicines are not used to suppress a cough where you cough up mucus. A productive cough helps clear secretions and mucus from the airways. Talk to your doctor if you have a productive cough that’s preventing you from sleeping.
