BA.2, also known as “Stealth Omicron”, is currently the dominant variant of Covid in the UK and has a faster transmission rate than the original Omicron strain.
The variant is about 1.4 times more infectious than BA.1, according to the World Health Organisation (WHO), and now accounts for 94% of coronavirus cases in England.

Hide AdWhat symptoms are more common of Omicron BA.2?
The Omicron variant has been found to cause a wider variety of symptoms than those first reported at the start of the pandemic, when only three signs were linked to the virus.
The recently expanded NHS list now reflects the diversity of symptoms that the virus can cause, with many being very similar to the common cold and flu.
Symptoms linked to BA.2 generally appear to be less severe than BA.1 (the original Omicron variant), which is reflected in the lower hospitalisation rate, but Prof Spector warned that people are likely to suffer from at least five symptoms if they are infected.

“We can see there is less headache, less abdominal pain, particularly with BA.2 compared to BA.1, but the overall picture really is reduced hospitalisation by about half, and about 50% more people having more than five symptoms.
“Early signs are that if you get it (BA.2) you are going to get a full package of symptoms and be less likely to go to hospital.
