Studies show BA.4 and BA.5 are more like Alpha and Delta.

Two new Omicron sub-variants are causing concern among experts, who say that they are leading to a worrying rise in cases - with one-in-21 Brits thought to be infected. Experts have warned that the country is already going through its fifth Covid wave, with BA.4 and BA.5 triggering a rise in infections in the UK.

It's believed the variants are therefore potentially more serious than Omicron but not as transmissible - although no new symptoms have been identified at this stage. What impact are they having on cases? According to the latest figures from the ZOE Covid Study, there are currently 285,507 new symptomatic cases every day in the UK on average each day.The recent increases in the UK is primarily due to a subvariant of Omicron. The BA.5 variant which is now dominant in the UK.

He told the Evening Standard: “The latest data suggests that these are now the dominant strains in the UK. But, so far, vaccination means those rising cases haven’t translated into a rise of severe illness or death with no increase in ICU admissions.” What are the symptoms of the new variants? The European Centre for Disease Prevention and Control labelled BA.4 and BA.5 as 'variants of concern' in mid-May this year.

Even if you have been fully vaccinated, you can still experience any or all symptoms of Covid, including the new Omicron variants.While some symptoms do overlap, it is slightly different to the Alpha variant.
