ST. LOUIS – A nasty flu bug is hitting the St. Louis area.

It's the 2009 H1N1 flu strain, more commonly known as "swine flu." The World Health Organization classified swine flu as a pandemic in 2009.

So far, the St. Louis County Department of Health says it hasn't seen outrageous numbers, but cases are spiking.

This year's flu vaccine does include the 2009 H1N1 virus strain, and health officials are urging everyone 6-months-old and older to get a flu shot.

Flu vaccines are still available. Visit the St. Louis County Department of Health's website to find a nearby location.
