Millions at Risk as Norovirus Cases Surge — Experts Warn You Can Catch It Twice

A highly contagious virus is spreading rapidly across the UK, with health officials warning that people can contract it more than once. The UK Health Security Agency (UKHSA) has confirmed that cases of norovirus, commonly known as the “winter vomiting bug,” have surged to record levels this season, surpassing figures seen in the past decade.

In a public health alert, experts have emphasized that the virus is evolving, and different strains in circulation mean previous infection does not guarantee immunity. As a result, individuals who have already had norovirus this season could catch it again.

What is Norovirus?

Norovirus is a highly contagious virus that causes gastroenteritis, leading to symptoms such as:

• Severe vomiting
• Diarrhea
• Stomach cramps
• Fever and fatigue

The virus spreads quickly in environments like schools, hospitals, and care homes, leading to outbreaks that can cause severe illness, particularly among the elderly, young children, and those with weakened immune systems.

How Long Do Symptoms Last?

Most cases resolve within 1-3 days, but dehydration can be a serious risk, requiring medical attention in severe cases.

Norovirus Cases Are Rising Rapidly

The UKHSA has reported a 168% increase in norovirus cases compared to the five-year seasonal average. In just two weeks, confirmed cases jumped by 29.4%, marking the highest infection rate since 2014.

Where is the Virus Spreading the Most?

• Care homes and hospitals are experiencing significant outbreaks.
• The elderly population is being disproportionately affected.
• Cases are rising in schools and workplaces, leading to absences and disruptions.

Health officials are warning that the real number of infections is likely much higher, as many norovirus cases go unreported.

Why Can You Catch Norovirus Twice?

Unlike some viral infections that provide long-term immunity, norovirus is caused by multiple strains that mutate rapidly.

Key Findings from the UKHSA Report:

• Two dominant norovirus strains are circulating—GII.17 and GII.4.
• People infected with one strain are not immune to another, increasing the risk of reinfection.
• The GII.4 strain is becoming more prevalent, meaning even those infected earlier in the season could be at risk again.

This ability to mutate and spread quickly makes norovirus difficult to control, leading to recurring outbreaks.

How to Protect Yourself from Norovirus

Unlike flu or COVID-19, there is no vaccine for norovirus. The best defense is strict hygiene and prevention measures.

1. Wash Hands Thoroughly

• Use soap and warm water for at least 20 seconds after using the toilet and before eating.
• Alcohol-based hand sanitizers are ineffective against norovirus.

2. Disinfect Surfaces Regularly

• Use bleach-based cleaning products to disinfect high-touch areas like:
• Doorknobs
• Light switches
• Kitchen counters

3. Stay Home If You Are Sick

• Avoid public places, work, and school until at least 48 hours after symptoms disappear.
• Do not visit hospitals or care homes to protect vulnerable individuals.

4. Hydrate & Rest

• Drink plenty of fluids to prevent dehydration.
• Stick to simple foods like toast and broth when recovering.

What Should You Do If You Catch Norovirus Again?

If you experience norovirus symptoms more than once this season, follow these steps:

• Isolate and avoid spreading the virus.
• Hydrate to prevent dehydration.
• Monitor symptoms—seek medical help if they worsen.
• Disinfect household surfaces to kill lingering virus particles.

For severe cases, particularly in elderly individuals or young children, contact 111 for medical advice.

How Norovirus is Impacting the NHS and Society

Hospital Strains:

• NHS staff shortages have worsened as healthcare workers fall ill.
• Wards are closing due to outbreaks in hospitals.

School Closures & Absences:

• Some schools have reported high student and staff absence rates due to infection.

Workplace Impact:

• Businesses are seeing higher sick leave rates, affecting productivity.

Final Thoughts: How to Stay Safe Amid the Norovirus Surge

With norovirus cases at record highs, UKHSA experts are warning that the virus is not only spreading faster but also causing reinfections.

Key Takeaways:

• Norovirus cases have surged by 168% this season.
• Two dominant strains mean people can catch it twice.
• Hygiene is the best protection—wash hands, disinfect, and stay home when sick.

As the UK battles the largest norovirus outbreak in years, public awareness and strict hygiene measures remain crucial in controlling its spread.
