While for some, the coronavirus pandemic might feel like a lifetime ago, the virus is unfortunately still something we ought to be mindful of. New reports say a fresh variant, NB.1.8.1, descended from the Omicron variant, has now been identified as a 'Variant Under Monitoring' by the World Health Organisation – meaning it's a mutation of the virus that experts are wanting to keep an eye on.
Initially, there was a spike in cases in China, but the NB.1.8.1. strain has now also been detected in the U.S., Indian and possibly the UK, although there isn't solid data on how widespread or likely that is just yet.
Before this sparks any panic, it's important to say this does not mean there's cause for concern, says Dr Suzanne Wylie, GP and medical adviser for IQdoctor. "Health officials are warning that this variant is spreading rapidly, suggesting it has enhanced transmissibility compared to circulating strains," she explains. "As with previous variants, we can expect it to become more prevalent globally over the coming weeks if current trends continue."
Dr Wylie adds that from a clinical standpoint, there's currently a lack of in-depth studies to assess the impact of the NB.1.8.1 variant.
"[But] based on preliminary observations, no rise in severity has been reported, and it is anticipated that current COVID-19 vaccinations will continue to be effective in preventing hospitalisation and severe illness, though this hasn't been formally studied for NB.1.8.1 specifically."
Here, we take a look at the new Covid variant symptoms to be mindful of and detail everything else we know about NB.1.8.1.
What is the NB.1.8.1. Covid variant?
According to Dr Wylie, this new variant "appears to follow similar patterns to previous Omicron variants", in terms of how contagious it is and how severely unwell it makes people. However, given this new strain is still in its infancy, more clinical data is needed.
"Any increase in community transmission could still impact vulnerable populations and healthcare services, so continued vigilance is appropriate whilst we await more comprehensive research," she adds.
Symptoms of the NB.1.8.1. variant
By now, we're likely all familiar with the more general Covid symptoms of a temperature, loss of taste or smell, and a cough. But when it comes the NB.1.8.1., Dr Wylie says early reports indicate symptoms are mild and "similar to earlier Omicron variants, including a sore throat, cough, and fever."
She stresses again that there's minimal research at this stage for this specific variant. "As a GP, I'd advise patients to remain alert for the familiar constellation of COVID symptoms we've seen throughout the pandemic: respiratory symptoms such as persistent cough, fever, sore throat, fatigue, headache, muscle aches, and loss of taste or smell," Dr Wylie advises. "Until we have more specific data on NB.1.8.1, our existing clinical recognition patterns remain the best guide."
What should I do if I think I have the new Covid strain?
The advice on how to approach a confirmed or suspected case of Covid has changed a lot since the early days of the pandemic – free, routine testing is no longer as readily available.
"The emphasis has shifted towards personal responsibility and protecting vulnerable individuals," says Dr Wylie, reminding that there are still people at greater risk of falling ill with Covid compared to the general population. It's important that those people are kept in mind if you suspect you have Covid.
"The general advice is to stay at home whilst unwell and avoid contact with others, particularly vulnerable people, until you feel better and no longer have a high temperature," notes the GP. "You should seek medical advice if symptoms worsen or if you're in a high-risk group."
If you work in healthcare, testing is still advised but routine community testing and reporting is no longer mandatory.
"The key principle is to behave responsibly," the doctor reminds. "If you're unwell with respiratory symptoms, treat it as potentially infectious regardless of the specific cause and take appropriate precautions to protect others."
