A new sub-lineage of the Omicron COVID variant now makes up one in seven cases in the UK.
EG.5 and EG.5.1 are descendants of Omicron, which was first detected in South Africa in late-2021 before becoming widespread in the UK.
This week the World Health Organisation (WHO) designated EG.5 as a ‘variant of interest’ after it was reported in 51 countries.
Here Sky News looks at it in more detail.
When was it discovered?
EG.5 was first detected on 17 February but was given ‘variant under monitoring’ status by WHO on 19 July following a spike in cases, particularly in Asia. As of 7 August it was a ‘variant of interest’.
Most reported cases are still in China (30.6%), followed by the US (18.4%), South Korea (14.1%) and Japan (11.1%).

According to the latest UK Health Security Agency (UKHSA) data, it is now the second most prevalent variant making up 11.8% of UK cases as of 27 July. As of 4 August, it represented one in seven UK infections.
The majority of cases are still the Arcturus strain, another Omicron sub-variant that emerged earlier in the year.

On a global scale, WHO claims EG.5 makes up 17.4% of infections as of 23 July, which it says is a “notable rise” on the last time it collected data on 25 June.
What are the symptoms?
According to the ZOE health app, the symptoms of EG.5 and EG.5.1, are similar to other Omicron sub-variants.
These include:
Runny or blocked nose
Headache
Fatigue
Sore throat
Sneezing
How worried should we be?
WHO has said that on the evidence available the “public health risk posed by EG.5 is low at global level” and similar to the other Omicron sub-variants we’ve seen in the past two years.
They haven’t found an increase in disease severity compared to ones we’ve seen previously either.
But it does have a growth advantage and immune escape properties, which means it can evade natural or vaccine-based immunity.
It predicts that: “Due to its growth advantage and immune escape properties, EG.5 may cause a rise in case incidence and become dominant in some countries or even globally.”
There have been increases in COVID hospitalisations in some Asian countries where EG.5 is circulating but there is no evidence of a link between the sub-variant and any spike in hospital admissions.
Professor Francois Balloux, an expert in computational systems biology and director of the UCL Genetics Institute, said it still “only plays a minor role in the current increase in cases”.
He says this is “driven primarily by the weather”, which has prevented people from spending more time outdoors in recent weeks, and “constantly waning immunity” from booster jab campaigns.
“There is nothing that feels particularly concerning about EG.5.1, relative to the many other Omicron sub-variants in circulation,” he said.
Biologist Professor T. Ryan Gregory who coined the nickname “Eris” for EG 5.1 on social media, adds that it “isn’t super notable in terms of specific mutations” and “is not even the fastest XXB (Omicron) variant”.
He added it is “one to watch even if it’s not expect to cause a large wave”.
But virologist Professor Stephen Griffin wrote on X, formerly known as Twitter, that “not being more severe than existing strains is not the same as not being severe”.
He warned that “individual risks scales by prevalence” and stressed the continuing risks of Long COVID and lack of immunity in the super clinically vulnerable.

Why UK COVID rates are rising again
What about COVID more generally?
Generally COVID cases are on the rise. Although universal testing and routine reporting of cases has ended in the UK, hospital admissions remain an indication of prevalence.
Currently the COVID hospitalisation rate is 1.97 per 100,000 people – compared to 1.17 a week earlier.
People aged 85 and over represent the biggest age group in hospital as they have throughout the pandemic.
According to UKHSA “overall levels of admission remain extremely low and we are not currently seeing a similar increase in ICU admission”.
Britain will be taking “a courageous step at a very difficult time” by officially recognising a Palestinian state, according to the authority’s foreign minister, who told Sky News she believes the announcement – expected in the coming days – will inspire more nations to follow suit.
The Palestinian Authority’s foreign minister, Varsen Aghabekian, told me Britain’s move was “better late than never”, and said “Britain, with its weight, can influence other countries to come forward and recognise, because that is the right thing to do”.
But she also said she is “very angry” with the White House over its “unwavering support” for Israel, and said that Israel’s refusal to pass on tax revenue was pushing Palestinian civil society to the brink of “collapse”.

Could recognition of Palestine change the West Bank?
She told me: “Britain has been supporting the existence and the flourishing of Israel for some time, but I think today Britain is looking at the matter objectively, in terms of the right of people, in terms of complying with international law, and in terms of the future of this area for both the Israelis and Palestinians.”

She rejected the idea that recognising Palestine was a reward for Hamas terrorism, saying that “non-recognition” would also be a “reward to the extremists” and said that “if we wait until Israel decides it wants to go into negotiations with the Palestinians, then it won’t happen”.
Aghabekian told me she expected Gaza to be returned to the Palestinians, but I put it to her that Israeli Prime Minister Benjamin Netanyahu was being empowered by the diplomatic support he receives from America, and in particular, US President Donald Trump.
So is she angry with the White House? “Very angry, because I expect the White House and the United States of America to align with international law, with human rights, with having no double standards.
“This unwavering support for Israel, this blind support, is not only harming the Palestinians but also Israeli society.”

The state of Palestine is already recognised by three-quarters of the United Nations’ members. It comprises two separate territories – the West Bank, including East Jerusalem, and the Gaza Strip. Together, they are officially known as the Occupied Palestinian Territories.
The West Bank has been subject to Israeli military occupation since 1967, while Gaza has been attacked by Israel since the Hamas attacks of 7 October 2023, when nearly 1,200 Israelis were killed and around 250 people were taken hostage.
Since then, more than 65,000 people have been killed in Gaza as Israel has sought to destroy Hamas and recover its hostages. There are 48 hostages still in Gaza, with 20 believed to be alive.
She confirmed to me that Mahmoud Abbas, leader of the Palestinian Authority, which governs the West Bank, “has given guarantees in letters to various leaders around the globe that said Hamas will not be part of the governance of the Gaza Strip” and insisted there was “probably a worldwide consensus” on the topic.

How has UK responded to Israel-Gaza conflict?
But she also insisted it was “not reasonable” to talk of completely erasing Hamas: “Hamas is an ideology, not a building that you bring down. Hamas is in people’s minds; in their heads.
“Those who support Hamas need to see a future, need to see something that is moving on the political level, need to see that there might be a state in which their children and their grandchildren might prosper.
“What people see today, whether they are Hamas supporters or not, they see darkness and they see destruction all over. They see violation of rights. They are helpless and hopeless. People need to see things are moving forward, and once that happens, there will be a shift in the mood, and they will look for a better future.”
But just as the Palestinians prepare to welcome recognition, Aghabekian said the West Bank was facing financial collapse as Israel continues to withhold hundreds of millions of dollars of tax revenue that, under a 30-year-old agreement, it collects on the Palestinian Authority’s behalf.
Israel has retained a proportion of the money since the start of the war in Gaza, but, encouraged by finance minister Bezalel Smotrich, it has recently withheld a much higher amount.
“People have not been paid, civil servants are only receiving small parts of their salaries. We can’t buy medical supplies, equipment, you name it,” said Aghabekian.
“How can a government run a country under such conditions? So yes, we are very worried.”
Passengers have been evacuated from Dublin Airport’s Terminal 2 as a “precautionary measure”.
Flights could be “temporarily impacted”, the airport said in a statement.
It did not give any details about the reason for the evacuation but said “the safety and security of our passengers and staff is our absolute priority”.
“We advise passengers to check with their airline for the latest updates,” the airport added, saying further information would be provided as soon as it is available.
This breaking news story is being updated and more details will be published shortly.
At least 70 people have been killed after a paramilitary drone attack on a mosque in Sudan.
The Sudanese army and aid workers said the paramilitary group Rapid Support Forces (RSF) carried out the attack during Friday prayers in the North Darfur region.
The attack took place in the besieged city of Al Fasher and was said to have completely destroyed the mosque.
With bodies still buried under the rubble, the number of deaths is likely to rise, a worker with the local aid group Emergency Response Rooms said.
The worker spoke anonymously, fearing retaliation from the RSF.
Further details of the attack were difficult to ascertain because it took place in an area where many international and charitable organisations have already pulled out because of the violence.
In a statement, Sudan’s army said it was mourning the victims of the attack.
It said: “Targeting civilians unjustly is the motto of this rebel militia, and it continues to do so in full view of the entire world.”

The Sudan war started in April 2023, when long-simmering tensions between the Sudanese army and the RSF broke out in Khartoum.
The US special envoy to Sudan estimates that 150,000 people have been killed, but the exact figure is unknown. Close to 12 million people have been displaced.
Several mediation attempts have failed to secure a humanitarian access mechanism or any lulls in fighting.
The Resistance Committees in El Fasher, a group of local activists who track abuses, posted a video on Friday claiming to show parts of the mosque reduced to rubble with several scattered bodies.
The Darfur Victims Support Organisation, which monitors abuses against civilians, said the attack happened at a mosque on the Daraga al Oula street at around 5am local time, citing witnesses.
The attack is the latest in a series of heavy clashes in the past week of between the two sides in Al Fasher.
