Covid-19 is back in the news as a new variant called NB.1.8.1 has been confirmed in the UK and other parts of the world.
Although more than five years have passed since the original outbreak, this new strain has now been detected in Northern Ireland and Wales, and is growing in places like the US, Australia, Thailand, China, and Hong Kong.
NB.1.8.1 is now responsible for over 10% of global Covid infections, and experts are keeping a close eye on it.
What It Is
NB.1.8.1 is a subvariant of Omicron, first spotted in early 2025. According to the World Health Organisation (WHO), it is now a “variant under monitoring”. This means scientists are tracking its spread, but there is no cause for panic just yet.
Here’s what we know:
-
It appears to be more transmissible than older variants.
-
It does not cause more severe illness, according to current data.
-
It may trigger more digestive symptoms like diarrhoea, constipation, and nausea something not as common in earlier Covid strains.
Experts also believe NB.1.8.1 infects cells more efficiently, helping it spread faster than others like XEC or LP.8.1, which were dominant earlier this year.

So What? Insights
The return of Covid-19 variants like NB.1.8.1 shows that the virus is still evolving. And while the world has moved on in many ways, viruses don’t take breaks.
This one is especially interesting because:
-
It’s spreading fast but not making people sicker.
-
It may affect your gut more than your lungs.
-
It’s a reminder that Covid is not over, and we need to stay informed.
Even though it doesn’t seem dangerous, a rise in cases could still pressure healthcare systems, especially during flu season or in countries with older populations.
Key Implications
-
Stay updated, not alarmed – There’s no reason to panic, but we should pay attention as this variant spreads.
-
Symptoms may vary – Stomach issues like nausea or diarrhoea could now be signs of Covid, not just the flu or food poisoning.
-
Vaccines still help – Even if not tailored to this specific variant, vaccines continue to lower risk of serious illness.
-
Health systems need to watch closely – If NB.1.8.1 becomes dominant, hospitals may need to prepare for small spikes.
Practical Takeaways
-
Know the symptoms: Apart from cough and fever, watch for tummy problems like nausea or diarrhoea.
-
Don’t ignore signs: If you feel unwell, consider testing especially if you’re around vulnerable people.
-
Keep hygiene habits: Regular handwashing, good airflow, and staying home when sick still work.
-
Stay informed: Variants come and go, but awareness helps us react early.

Final Thoughts
The NB.1.8.1 Covid variant isn’t causing major concern yet, but it’s spreading fast and showing new symptoms. It’s a reminder that Covid isn’t fully behind us.
The good news? Experts say it’s no more dangerous than previous strains. But staying alert and informed can help keep ourselves and our communities safe.
