Pandemic Influenza (Flu)

Flu is widespread in many communities but is not currently a pandemic.

A flu pandemic occurs when a new flu virus spreads to people all over the world. Pandemic flu is not the same as seasonal flu. Learn more about pandemic flu.

The 2009 H1N1 flu (swine flu) pandemic officially ended as of August 10, 2010, but the virus hasn’t gone away. The World Health Organization (WHO) cautions that the H1N1 flu virus is circulating along with this year’s seasonal flu viruses and may still cause serious disease—particularly among younger age groups and others at high risk during the post-pandemic period.
