Doctors see spike in norovirus, flu cases as the 2025 holiday season arrives

A virus is the last guest anyone wants showing up during the holidays, but medical experts say more people are getting sick right before holiday season gets into full swing.

Doctors at Duke University Hospital say flu cases are rising earlier than normal, while norovirus cases are also spiking in the Triangle and nationwide.

Hayes Barton Pharmacy Owner & Pharmacist Brent Talley says they're seeing more people coming in and getting sick.

"This time of year, leading into the fall and winter, you always see a spike in respiratory illnesses," he said.

Duke University Hospital Emergency Department Medical Director Dr. Lauren Siewny says a large influx of patients usually visits the emergency department this time of year.

"This is kind of a busy season for the emergency departments," she said. "It's holiday season, but it's also flu season, and virus season, and all the other things that come along with it."

It's a little bit busier, though, because of more people getting sick right around the holidays.

ABC News Medical Contributor Dr. Alok Patel says people are getting sick with more than just the cold.

"We are seeing a rise in influenza, and a rise of other viruses as well, also norovirus, which is a really painful source of food poisoning," he said.

Norovirus, commonly known as a GI bug, is also spreading at a higher rate, just in time for everyone to come together for Thanksgiving.

Medical experts say the best line of defense is constant hand washing.

"Wash your hands really well everywhere you go," said Talley. "If you're around somebody that you know is sick or you are suspicious that they're sick, then wear a mask."

But doctors say it's important to know which symptoms to look out for to distinguish between the symptoms from an undercooked turkey and a serious infection.

"If you're having severe abdominal pain, shortness of breath, chest pain, those are going to be the things that really get us interested in having those folks come to the ED for evaluation," said Siewny.

Patel says be mindful of passing around food and sharing utensils as well.

"Pay really close attention to when people are gathering and there's eating, and sharing your utensils and plates involved, because this virus can spread very easily, especially with infected surfaces," said Patel.

Doctors say another important line of defense is the flu shot.

They say it will take at least two weeks before building up all the antibodies needed to stay healthy this holiday season.
