Norovirus, often called the “winter vomiting bug,” is a highly contagious virus that frequently affects children and families, particularly during the colder months. This virus causes gastroenteritis, leading to symptoms like nausea, vomiting, diarrhoea, and sometimes fever and aches. Symptoms can start as quickly as 12 to 48 hours after exposure, and while uncomfortable, they usually resolve within a few days.
Children
Children are particularly vulnerable to norovirus due to close contact in nurseries, schools, and family settings. It spreads easily through contaminated surfaces, direct contact with an infected person, or eating contaminated food. Young children who catch norovirus may struggle to stay hydrated, as vomiting and diarrhoea deplete fluids quickly. Parents should encourage small, frequent sips of water or rehydration solutions to prevent dehydration, which is a common complication.
Reduce the Spread
To reduce the spread, parents should keep children with symptoms out of school or daycare until they’ve been symptom-free for 48 hours. Proper handwashing with soap is essential, as alcohol-based hand sanitizers are not effective against norovirus. While it usually resolves without needing medical care, parents should seek urgent help if a child shows signs of dehydration, such as reduced urine output or lethargy.
Cleaning
For parents, dealing with norovirus in the household can be challenging. Cleaning contaminated surfaces with bleach-based products and washing hands frequently can help contain the virus. While norovirus can be distressing, especially for young children, with supportive care and vigilance against dehydration, most children recover quickly without lasting effects.
