The influenza virus is peaking across the country and the number of related deaths and hospitalizations are on the way up.

According to UPI.com, there have been 13 flu-related deaths reported in North Carolina and nine in Texas. North Carolina health officials said the flu is affecting middle-aged and young adults. 12 of the 13 deaths were adults younger than 65.

According to the Centers for Disease Control and Prevention (CDC), this year's flu season is on par with past averages. Still, several states are encouraging safety practices to try and stop the spread.

In a recent weekly flu report, the CDC said 4.3 of every 100,000 people in the U.S. have had lab-confirmed hospitalizations for influenza. The rates are on the rise, but are not yet approaching the classification for a pandemic.

Several states across the nation, like Indiana, are encouraging residents that it is not too late for a flu shot.

"Flu activity is increasing around the state," Indiana's Health Commissioner Dr. William VanNess told the Guardian Liberty Voice. "The recent deaths remind us that influenza can be very serious and even deadly. I encourage all Hoosiers to become vaccinated from flu to protect themselves, their families and the community."

He said people should follow what he called the "three C's" for sickness prevention:

"Clean your hands often with soap and warm water."

"Cover your cough and sneeze using your sleeve or a tissue."

"Contain your illness by staying home when you are sick."

The CDC also has its three-step plan to prevent the flu.

The first is vaccination and, although flu season is currently at its peak, it is not too late to get vaccinated. Anyone over the age of six months, especially pregnant women, young children and the elderly are encouraged to get a flu shot.

The second are daily hygiene habits, like the "three C's" rule. You never know who you interact with is carrying, so, in this case, it is better to be safe than sorry.

The last is following doctor's instructions for any prescribed medications. This especially applies to patients with high health risks. If you have flu-like symptoms for more than one day, it is time to see a doctor.
