What is a flu?

The Flu. Influenza - or flu - causes similar symptoms to a cold but tends to be a more severe illness. Although it is also self-limiting in most people, flu can be dangerous for people who are frail or have a weakened immune system. Generally, there are two peaks for influenza occurrence in Hong Kong - one in February and the other in July, but this can be influenced by imported cases of flu from other countries.
