Because the Covid-19 pandemic rages, lingering concern stays over the potential for brand spanking new and extra dangerous variants.
The present dominant pressure is the Omicron variant, however viruses mutate and alter over time, which means they are often arduous to maintain on high of.

It’s hoped that the mass rollout of the vaccine will assist individuals within the UK keep away from catching the virus sooner or later.

So what’s it and what do we all know up to now?

The BA.2 sub-strain is called the ‘stealth Omicron’ because it reportedly can keep away from detection from sure varieties of PCR check.
This can be a concern as PCR assessments are very important for detecting the virus extra precisely. On this case, BA.2 has a slight anomaly completely different to the dominant BA.1 sub-strain that PCR assessments search for, making it more durable to detect.
The sub-strain is also called the ‘BA.2 lineage’.
Final week, Denmark reported that the sub-strain was making up for practically half of the nation’s circumstances, and that as circumstances of it elevated, general circumstances jumped to a file excessive.
The World Well being Organisation (WHO) mentioned : “Whereas the BA.1 lineage has beforehand been probably the most dominant, latest traits from India, South Africa, the UK and Denmark recommend that BA.2 is growing in proportion.”

We already know that completely different variants of Covid carry with them barely completely different signs, as victims of Omicron reported they have been extra prone to expertise cold-like signs of a runny nostril and sore throat.
A UK Well being Safety Company (UKHSA) report from January 14 mentioned: “Signs in NHS Take a look at and Hint information [show] lack of odor or style was reported much less usually by Omicron circumstances than Delta circumstances.”
Though, the report additionally acknowledged that: “One other latest examine noticed improve in [a] sore throat additionally being reported amongst those that check damaging for [Covid] so this can be an incidental discovering.”
It’s at present unclear if Omicron sub-variants carry with them barely completely different signs.
The 5 most typical Omicron signs, as reported by the ZOE Covid examine, are as follows:
- Runny nostril
- Headache
- Fatigue (delicate or extreme)
- Sneezing
- Sore throat

Additional analysis into the sub-variant is underway to try to decide if it’s a trigger for concern.
The UK Well being Safety Company (UKHSA) has confirmed the pressure has been classed as a variant beneath investigation.
Dr Meera Chand, incident director of the UKHSA, mentioned to Nationwide World : “It’s the nature of viruses to evolve and mutate, so it’s to be anticipated that we’ll proceed to see new variants emerge.”
In the meanwhile, additional examine must happen to find out if BA.2 is extra dangerous than the BA.1 pressure of Omicron, which is at present dominant.
The WHO mentioned: “Research are wanted to higher perceive the properties of BA.2, together with comparative assessments of BA.2 and BA.1 for key traits reminiscent of transmissibility, immune escape and virulence.”
Anders Fomsgaard, chief doctor and virus researcher on the Statens Serum Institut (SSI), instructed Danish media: “We can not see any distinction in hospitalisation numbers, demise charges with BA.2, so it isn’t one thing that worries us but.”
What to do you probably have Covid signs
In case you assume you might have Covid, you must take a lateral circulate check (LFT) as quickly as attainable to find out if you’re constructive for the virus.
