This virus is surging across America & there’s no treatment. Here’s how to stay safe

Colder weather often leads to a surge in illnesses. However, one in particular has been spreading at a rapid rate across America.

Norovirus is the the leading cause of vomiting and diarrhea in the United States. It infects an average of about 20 million U.S. residents annually, according to the CDC. There are about 2,500 reported norovirus outbreaks in the United States each year.

There is no data of the exact number of norovirus cases in Texas, because the state is not a part of the Centers for Disease Control’s norovirus reporting network, and Texas health care providers aren’t required to report cases to local and state authorities.

From August 2024 to January 2025, the CDC recorded 1,078 reports of norovirus outbreaks. That’s a 94 percent increase from the same period last seasonal year.

Last March, local Tarrant County doctors also reported a surge in norovirus cases.

This is a testament to how highly contagious the virus is. William Shaffner, a National Foundation for Infectious Diseases spokesperson, says that it only takes a few viral particles to infect someone.

Norovirus can be passed between human contact, but the virus is also able to survive on environmental surfaces and in food. In rare cases, it can also spread through soft water.

Norovirus is most prevalent between November and April. Doctors are concerned about the virus every year, but in years where a new strain of the virus is dominant — like this year — illness rates can increase, according to the CDC.

Here’s what you should know about symptoms, treatment, and when to seek medical help.

Is norovirus just a stomach bug?

Norovirus is not just a stomach bug or food poisoning, though it is often mistaken for those things.

It is a highly contagious virus that causes diarrhea and vomiting.

The worst part about it: There is no specific medicine to treat norovirus. Those who get infected just have to let the illness play out. It typically lasts one to three days, according to the CDC.

How does norovirus spread?

You can get norovirus if:

  • You have direct contact with someone infected with norovirus (caring for them, sharing food utensils, eating food handled by them)

  • You eat food or drink liquids contaminated with norovirus

  • You touch contaminated objects or surfaces and then put your unwashed fingers in your mouth

You can still spread norovirus for two weeks or more after you feel better.
