Key difference between XFG.3 and Nimbus Covid variants that are spreading globally

Winter is fast approaching and with it comes the colds and illnesses that are common as temperatures drop.

Unfortunately, that also means that Covid is likely to become more prevalent once again, with two new variants spreading quickly throughout the world.

Thanks to vaccines, we're unlikely to see another national lockdown anytime soon but health officials are warning people to be wary of both variants of the disease.

After first being identified in Southeast Asia and China in the summer, the XFG.3 strain, known as 'Stratus', and NB.1.8.1 strain, known as 'Nimbus', are now the most common Covid variants in the UK, according to the UK Health Security Agency (UKHSA).

Although it has been suggested that the two are only likely to cause minor illnesses, the World Health Organisation is keen to monitor both as they have quickly spread across the world into Europe and the US.

While Covid tests and social distancing are a distant memory, much like when you have any sort of illness or bug, it is recommended that you stay at home and avoid contact with others if you do come down with the disease.

The UKHSA is also urging people to book a Covid vaccine, especially those over the age of 75 or those who are immunosuppressed, as they are eligible for a free jab from the NHS.

It said: "It's normal for viruses to mutate and change, and as more data becomes available on these variants, we'll have a better understanding of how they interact with our immune systems and how to optimise our protection, as well as actions we can take to keep the most vulnerable safe and live our lives as normally as possible.

"The most important thing is for those eligible to get their vaccination when it is due."

What are the symptoms of Stratus?

Both strains still possess many of the symptoms we associate with Covid, including shortness of breath, chest tightness, sore or scratchy throat, headaches, body aches, upset stomach, nausea, and loss of taste or smell.

However, those suffering with Stratus have reported a persistent dry cough, tiredness and a fever.

Scientists have also claimed that Stratus appears to be better at evading the immune system, meaning it might be a bit harder to shake off, even if you're eating fruits and superfoods on a regular basis.

What are the symptoms of Nimbus?

Not to be confused with Harry Potter's broomstick, the Nimbus Covid variant is leading some folks to experience a particularly painful sore throat, which has been compared to 'swallowing razor blades'.

As well as the usual Covid symptoms, Nimbus also often leads to a hoarse voice, which can be helped with some honey, according to the NHS.

With cases on the rise, it's definitely worth remembering some of the habits we adopted during the pandemic as a way to stay safe this winter.
