Norovirus is a highly contagious virus causing acute gastroenteritis — sudden vomiting and diarrhoea. It spreads easily in close-contact settings and typically resolves within a few days.
Common symptoms
Sudden onset of nausea, vomiting, watery diarrhoea, stomach cramps, and sometimes low-grade fever, body aches, or headache.
General self-care measures
- Stay hydrated with small, frequent sips of fluid, or an oral rehydration solution, especially important for young children and older adults (see Dehydration Care).
- Rest until symptoms subside.
- Stay away from others, especially food preparation, until at least 48 hours after symptoms resolve — norovirus remains contagious for a period after symptoms stop.
- Practice thorough handwashing with soap and water — alcohol-based hand sanitizer is less effective against norovirus specifically.
When to seek medical attention
- Signs of dehydration (see Dehydration Care): reduced urination, dizziness, extreme thirst, or lethargy.
- Inability to keep fluids down for an extended period.
- Blood in vomit or stool.
- Symptoms lasting more than a few days without improvement, especially in infants, older adults, or those with underlying health conditions.
Common pitfalls
- Returning to work, school, or food handling too soon — remaining contagious for up to 48 hours or more after symptoms stop is a key reason norovirus spreads so easily in shared settings.
- Relying on hand sanitizer alone for hygiene — norovirus is relatively resistant to alcohol-based sanitizers; thorough soap-and- water handwashing is more effective.
- Underestimating dehydration risk, especially in children and older adults — both groups can dehydrate quickly from vomiting and diarrhoea and may need medical attention sooner than a healthy adult.
