Experts also know the country is facing the health and economic burden of a double-flu season.
While so far the symptoms and complications of H1N1 are no different from seasonal flu, children and young adults seem to be more vulnerable.
"For some reason, with H1N1, we're not seeing as many older people," Hendrix said.
Keep yourself safe in the pandemic. Stay at least six feet away from people with a cough. If you're at risk of complications, get the vaccine for both seasonal and H1N1 flu.
And you know to wash your hands, but alcohol-based sanitizers protect against the virus if rubbed into the hands until dry.
"We have seen some deaths associated with H1N1, but it's what we would associate with a typical flu season," Hendrix said.
