- Who is most at risk from severe norovirus infection?
- For most adults, symptoms last 1-3 days, but it's most dangerous for young children, the elderly, and those with compromised immune systems, who may experience chronic infections.
- How long can norovirus remain infectious on surfaces?
- Norovirus is highly contagious and can persist on surfaces for weeks, making hygiene crucial for prevention. Thorough cleaning with bleach solution is recommended, as many disinfectants are ineffective against it.
- Which foods are most often linked to norovirus outbreaks?
- Foods often linked to norovirus outbreaks include leafy greens, fresh fruits, and shellfish, often due to contamination during farming or preparation. Cooking inactivates the virus; raw consumption is riskiest.
- What measures can be taken to prevent the spread of norovirus?
- To prevent spread, infected individuals should isolate themselves, avoid sharing personal items, and not prepare food for others. Good hand hygiene is crucial, and thorough cleaning of the house is also advised.
- Is there a cure for norovirus, and what is the treatment approach?
- There's no cure for norovirus, but treatment focuses on managing symptoms. Hydration is vital, and those with compromised immunity should seek professional help. Infectiousness can persist for weeks after symptom resolution.
