How long can norovirus survive on surfaces?

Question

Hello doctor,

I live in a college dorm, and almost everyone on my floor has been getting sick with vomiting and diarrhea over the past few days. Some students recover in a day or two, but others are still weak even after four or five days. I had symptoms two days ago and felt better yesterday, but now I have stomach pain and nausea again. I have been trying to stay hydrated with electrolytes, but I feel exhausted and lightheaded when I stand up.

Could this still be norovirus, or should I be worried about something else like dehydration or secondary infections? Also, we are cleaning shared spaces with disinfectant, but people are still getting sick. How long can norovirus survive on surfaces, and what is the best way to stop it from spreading? Should I take any probiotics to help recover faster?

Please help.

Hello,

Welcome to icliniq.com.

I understand your concern.

Norovirus is a highly contagious virus that causes gastrointestinal symptoms, including vomiting, diarrhea, stomach pain, and nausea. The outbreak in your dorm may be due to norovirus.

Duration of illness:

Norovirus symptoms typically last one to three days, but some people may experience prolonged or recurring symptoms.

Dehydration and secondary infections:

Dehydration is a concern, especially if you are experiencing excessive vomiting or diarrhea. Monitor your hydration levels and seek medical attention if you experience severe dehydration symptoms, such as:

Excessive thirst.
Dark urine.
Dizziness or fainting.
Rapid heartbeat.

Secondary infections, like bacterial infections, can occur if norovirus weakens your immune system.

Norovirus can survive on surfaces for:

Up to two weeks on hard surfaces.
Several days on soft surfaces.

To reduce the spread of norovirus:

Clean and disinfect high-touch surfaces, like doorknobs, light switches, and countertops, with a bleach-based disinfectant.
Use disposable gloves when cleaning.
Wash your hands frequently with soap and water.

Probiotics for recovery: Some probiotics, like Lactobacillus or Bifidobacterium, may help alleviate norovirus symptoms and support gut health.

I hope this has helped you.

Thank you.
