Norovirus: What to know and how to prevent it

Quick Summary

  • Norovirus is a virus that spreads very easily and quickly.
  • There have been recent reports of outbreaks in regions across the county, including in the Northeast.
  • You can help prevent infections by washing your hands, practicing food safety, and taking steps to avoid spreading it to others if you do get sick.

NOROVIRUS spreads easily.Norovirus is very contagious and causes vomiting and diarrhea. People of all ages can get infected and sick with norovirus. Hand sanitizer does not kill norovirus. Wash your hands thoroughly with soap and water for 20 seconds.Norovirus (sometimes called stomach flu or stomach bug), is a virus that causes vomiting, diarrhea, nausea, and stomach pain. Norovirus spreads very easily and very quickly. People of all ages can get sick from norovirus. Most people with norovirus get better in 1 to 3 days.

Like other gastrointestinal (stomach and intestines) illnesses, norovirus spreads throughout the year, but is most common from November to April. Each year, 19-21 million people get sick and there are about 2,500 reported outbreaks in the United States. There have been recent reports of outbreaks in regions across the county.

People get norovirus by accidentally getting tiny particles of feces (poop) or vomit in their mouth from a person infected with norovirus. This can happen when you have direct contact with someone who is sick, have contact with contaminated surfaces and objects and then touch your mouth, and when you eat foods and drink liquids contaminated with norovirus. See examples of when this can happen.

Steps to Prevent Norovirus

Norovirus is very contagious, but there are ways you can prevent it.

  • Wash your hands often with soap and water for at least 20 seconds. Hand sanitizer does not work well against norovirus. It is especially important to wash at key times: after using the toilet or changing diapers, before and after eating, and before and after caring for someone who is sick.
  • Practice food safety to help prevent norovirus. Keep up the healthy habits in your kitchen:
    • Wash your hands before, during, and after preparing food.
    • Rinse fruits and vegetables well.
    • Keep your kitchen utensils and surfaces clean.
    • Cook oysters and other shellfish to an internal temperature of at least 145°F.

Steps to Take if You Get Norovirus

If you get sick with norovirus, stay hydrated and take steps to stop it from spreading to others.

  • Drink plenty of liquids to avoid dehydration and potentially serious health problems. If you, or some you are caring for, becomes dehydrated, contact a healthcare provider.
  • Stay home and away from others while you are sick and for at least 48 hours after your symptoms stop. You should also avoid preparing food for others — at home and at work — while you are sick and for at least 48 hours after symptoms stop.
  • Immediately clean and disinfect the entire area around where someone vomits or has diarrhea. You should also wash any clothing or linens that get vomit or poop on them right away. See how to clean and disinfect.
