What we know about the new COVID-19 variants Eris and Pirola

What we know about the new COVID-19 variant Eris

As a virus spreads from person to person, its genetic make-up gradually changes. This mutation process helps to ensure the virus can survive, to allow it to continue spreading and reproducing.

Since it emerged, كوفيد-19 has continued to mutate into many different variants, which has enabled it to evade immune responses and كوفيد-19. So even though getting your jabs will prevent against serious illness, they may not always stop you from getting the virus. However, your symptoms will be milder.

One of the newest COVID-19 variants - called EG.5.1 or Eris - emerged in the UK over the summer. First classified as a variant by the World Health Organization (WHO) on 9th August¹, it is a descendent of the أوميكرون variant which first appeared in November 2021 and has had many sub-variants.

Eris is now the second most common variant in the UK² and the most prevalent in the United States, according to the Centers for Disease Control and Prevention (CDC)³.

What are the symptoms of Eris?

Currently, there is no evidence to suggest Eris causes any new COVID-19 symptoms. The symptoms we are aware of include - الحمى, aches and pains, a continuous سعال, changes in taste and/or smell, الإرهاق, runny nose and a التهاب الحلق.

Is Eris dangerous?

Although hospital admissions for COVID-19 have risen over the summer⁴, the WHO has said the public health risk posed by Eris is low. The rise in cases and hospital admissions have been attributed to waning immunity and a rise in indoor mixing because of the wet weather.

Mary Ramsay, head of immunisation at the UK Health Security Agency, said in a statement: "The latest data shows that كوفيد-19 cases continue to rise. To help combat the spread of the virus, we continue to advise that anyone with symptoms of a respiratory infection should try to stay at home and away from others - especially those who are vulnerable.

"Hospitalisations are also increasing, but still remain at very low levels. ICU admissions have increased in this week's report, but remain extremely low."

The best way to protect yourself from any COVID-19 variant is to keep up-to-date with your جرعة معززة vaccinations, as this protects you against severe disease.

Another COVID-19 variant called BA.2.86 or Pirola is also spreading⁵. Like Eris, Pirola is another sub-variant of أوميكرون. This variant was detected in the UK on 18th August and has also been identified in Israel, Denmark and the US.

ما هي أعراض بيرولا؟

The symptoms of Pirola are similar to other COVID-19 variants and include - الحمى, aches and pains, a continuous سعال, changes in taste and/or smell, الإرهاق, runny nose and a sore throat.

Is Pirola dangerous?

Experts have noted that Pirola has many genetic differences from previous versions of COVID-19⁶.

Because this variant has more mutations, it may be more likely to cause ‘breakthrough infections’ - where people still get infected with the virus despite being fully vaccinated. However, being vaccinated prevents serious illness if you do catch كوفيد-19.

It is too soon to know whether the Pirola variant will cause more severe illness compared with previous variants, according to the CDC. At the moment, though, there's no evidence to suggest it's more dangerous.

It's important to get your كوفيد-19 to prevent against serious illness with any variant of COVID-19.
