Cases were on the rise as infections rapidly spread as Americans gathered for the holidays.

The latest data from the Centers for Disease Control and Prevention show nearly five million cases across the country.

Illinois’ numbers are lower, compared to other states.

New York is seeing ‘high’ respiratory illness activity. Alabama, Colorado, Connecticut, Hawaii, Louisiana, Maryland, Minnesota, New Hampshire, New Jersey, Ohio, Rhode Island, and Texas are seeing ‘moderate’ activity. All other states are seeing low or very low levels.

While this year’s flu seems similar to previous years, including symptoms like high fever, body aches and fatigue, doctors said this year’s strain is showing more vomiting in children and symptoms are coming on faster and more intensely.

The bulk of this year’s cases are being linked to a new variant known as subclade K.

Doctors say the flu shot will still help reduce your risk of severe illness. However, fewer Americans have been vaccinated this year.

“It’s a good idea to go and swab and get tested, because you might be able to take an antiviral such as Tamifu for influenza, as long as you start that quickly, usually within 48 hours of symptoms,” ABC News medical contributor Dr. Alok Patel said.

The CDC recommends everyone over the age of 6 months get their flu shot.
