# Norovirus Care

> ⚠️ **Ask your doctor or health care professional. This information is AI generated for education and NOT medical advice.**

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.
