Tips

To effectively prevent and manage norovirus infection, consider the following tips:

Tip 1: Wash Your Hands Regularly

Frequent handwashing with soap and water is crucial for preventing the spread of norovirus. Wash your hands thoroughly for at least 20 seconds after using the bathroom, before eating, and after coming into contact with someone who is sick.

Tip 2: Disinfect Surfaces and Objects

Norovirus can survive on surfaces for days, so it's essential to disinfect frequently touched areas and objects. Use a household bleach solution or other EPA-registered disinfectant to clean countertops, doorknobs, toys, and any other surfaces that may have been contaminated.

Tip 3: Avoid Raw or Undercooked Foods

Norovirus can be transmitted through contaminated food, particularly shellfish and leafy greens. Avoid consuming raw or undercooked seafood and wash fruits and vegetables thoroughly before eating them.

Tip 4: Stay Home When Sick

If you experience symptoms of norovirus, such as nausea, vomiting, or diarrhea, stay home to prevent spreading the infection. Avoid contact with others until you have recovered and your symptoms have subsided.

Tip 5: Consult a Healthcare Professional

Although most cases of norovirus resolve on their own within a few days, seek medical attention if you experience severe symptoms, such as persistent vomiting or diarrhea, high fever, or dehydration. Fluid replacement and other supportive measures may be necessary.

By following these tips, you can significantly reduce your risk of contracting norovirus and help prevent its spread in your community.
