Norovirus: The Winter Vomiting Bug

Ever heard of the winter vomiting bug? It's another name for the norovirus, which sickens an estimated 685 million people each year.

Here is everything you need to know about norovirus this winter.

What are the symptoms of norovirus?

Common symptoms of norovirus include the following:

• Stomach pain
• Nausea
• Vomiting
• Diarrhea
• Body aches
• Headache
• Fever

After you have been exposed to norovirus, you are most likely to develop symptoms within 12 to 48 hours. Symptoms usually subside after one to three days.

How does norovirus spread?

Norovirus spreads through tiny particles of feces and vomit from infected people. These particles can spread in various ways, such as through contaminated food, water, and surfaces and exposure to sick people.

According to the Centers for Disease Control and Prevention (CDC), infected people can spread norovirus for as long as two weeks after they feel better.

How can I prevent norovirus infection?

Although there is no vaccine to help prevent norovirus, there are a few steps you can take to prevent this illness:

• Carefully wash all fresh fruits and vegetables.
• Wash your hands with soap and water before eating or preparing food, after using the bathroom or changing a diaper, and before and after administering medicine to someone.
• Wash laundry thoroughly, especially if it is likely contaminated with vomit or fecal matter.
• Clean and disinfect frequently touched surfaces.

If you are sick, avoid caring for other people or preparing food to prevent transmission from yourself to others. Also, wash your hands frequently.

What are the treatments for norovirus infection?

There is no specific prescription or over-the-counter medication to treat norovirus at this time, according to the CDC. Some OTC medications can treat symptoms like fever, but none target the virus directly.

Keep in mind that antibiotics will not treat norovirus because these drugs target bacteria. Norovirus is a virus.

Because norovirus infection can cause vomiting and diarrhea, dehydration is one of the main risks of this illness. If you are sick with norovirus, drink plenty of water and other fluids to remain hydrated.

It's especially important to watch for dehydration in young children because they might not be able to communicate that they are feeling dehydrated. Crying with no tears or acting unusually fussy or sleepy can be signs of dehydration in young children.

If you are concerned about any of your symptoms, reach out to your health care provider.
