Catch it. Bin it. Kill it.
Once flu is spreading, apart from vaccination, hygiene is the main method that can help prevent spread.

"Through this campaign we are urging everyone to carry tissues and to use them to catch coughs or sneezes, to bin the used tissues as soon as possible and then to wash their hands and kill the germs."
