Winter Vomiting Bugs: Why They’re So Common and How to Reduce the Risk
Winter vomiting bugs is a broad term used to describe viral stomach infections that are more common during colder months. These infections spread rapidly and can affect people of all ages.
Why do stomach bugs increase in winter?
Several factors contribute to their spread:
People spend more time indoors and in close contact
Viruses survive longer on surfaces in cooler conditions
Increased pressure on shared facilities such as public transport, schools and workplaces
Norovirus is the most common cause, but other viruses can also be responsible.
Common symptoms
Winter vomiting bugs typically cause:
Sudden vomiting
Diarrhoea
Stomach cramps
Mild fever
Fatigue
Symptoms usually appear quickly and resolve within a few days.
How to protect yourself and others
Good hygiene is the most effective way to reduce spread:
Wash hands thoroughly with soap and water
Clean frequently touched surfaces regularly
Avoid sharing towels or utensils
Stay home while unwell and for 48 hours after symptoms stop
Supporting recovery
If you catch a winter vomiting bug:
Drink fluids little and often
Rest as much as possible
Eat only when you feel ready
Avoid dehydration, especially in children and older adults
When to seek advice
Professional advice should be sought if:
Symptoms are severe or worsening
There are signs of dehydration
Vomiting or diarrhoea lasts more than a few days
Winter vomiting bugs are common, highly contagious, and usually short-lived, but good hygiene and early self-care can make a big difference.
